GR 10 Voyage Tips and guide

Contents

The GR 10 is one of the paths and trails of the extensive Grande Randonnée (or GR) network. It crosses France, from the Mediterranean coast to the Atlantic coast, and runs almost entirely through the Pyrenees. While the trail is in France, much of it is near, or even on, the border with Spain. The trail can be walked in either direction, though some suggest that the west-east route is easier in the beginning, as it is both cooler and less steep that the corresponding start heading west; this may be an advantage to those not fully in shape.

Moving from west to east, the trail begins in Hendaye on the Atlantic Ocean, and finishes on the Mediterranean, in the small town of Banyuls sur Mer. Hikers will usually be able to make it to a gîte or small town every other night, and quite frequently every night. Expected time to complete the trail is around 6-7 weeks, though the majority of people only hike sections of it.

The trail is fairly well marked with painted marks on rocks, trees, telephone poles, and even houses, walls, and street signs. If you haven’t seen a waymark for 100 metres, you’ve likely strayed off the trail. Retrace your steps to the last marker and check your route. It is not realistic to navigate using the markers alone. A trail guide, at minimum, or a topologic map is required.

Sunburn is a particular problem, and clothing such as long sleeved shirts and long pants should be worn as they protect from the sun, scratching branches and insects. Sunscreen and a wide-brimmed hat are highly desirable.

One of the advantages of the GR 10 is that it can be hiked with minimal gear, as one can eat dinner and breakfast almost every day at the gîtes. Additionally the hiker can sleep outdoors on clear nights and pay for a bed in a gîte in inclement weather. On nights that only shelters (which usually have no food or staff) are available, pre-purchased food can be eaten.

If one plans to eat at gîtes and buy food from supermarkets that can be eaten without cooking, the absolute minimal gear in the summer months is:

• Sleeping bag or sleep sheet, and a mat for comfort.
• Goretex jacket and fleece or similar for cold or wet weather
• Long-sleeved shirt and pants
• Short-sleeved shirt and shorts (including shorts you can wear for swimming)
• Sunscreen and wide-brimmed hat
• Adequate footwear. Anything less than hiking boots may prove insufficient.
• Bottles for at least two litres of water, and a purification method for treating water from streams.
• Toiletries and a medical kit

Additionally, consider a rain jacket or fleece top for wet or cold weather.

If you plan to forgo the comforts and delicious food of the gites and hotels, also bring:

• Tent
• Cooking gear and food

A note on footwear: some four fifths of the hikers wear full hiking boots and thick socks. While running sneakers may suffice (and Choco-style sandals may work for a few days), your risk of injury is higher, and much of the trail involves hopping around on possibly wet and sharp rocks. Choose conservatively, depending on the length of your hike and your experience.

Accessing the start and end points is straightforward via public transport.

The GR 10 begins at Hendaye Plage, the main beach in Hendaye. Hendaye is well-connected by the French railway network. 43.353139-1.7819721 Hendaye station is the main international train station, with services from major French cities including Paris by TGV. From here, you can take a local bus to the start of the trail. Buses run from the main train station to the beach area where the trail begins. 43.369998-1.7643472 Gare des Deux-Jumeaux is a smaller station closer to the beach and the official starting point of the GR 10. It is served by local TER trains. From here, it is a short walk to the trailhead.

The GR 10 concludes in the Mediterranean town of Banyuls-sur-Mer. 42.4830563.1280563 Banyuls-sur-Mer railway station is located in the center of the town and is served by TER regional trains, which connect to major hubs like Perpignan. From the station, it is a short walk to the town center and the seafront where the trail officially ends.

The hike starts from the 3 km long 43.371238-1.7857621 Hendaye Beach. This is below the old casino, now known as Résidence Croisière. A 43.368436-1.7798331 Decathlon store geared towards watersports is available for last minute purchases, such as gas cannisters. The trail passes through Hendaye, leaving town, and pases by 43.333333-1.7430561 Biriatou , which conveniently has public toilets available. After about 3 hr you reach the summit of 43.325644-1.72172 Xoldokogaina. The high point is at Mandale on the Spanish border, with an altitude of 530 m. From here, the path descends past 43.3092-1.70333 Redoute de la Baïonette, a fortification near Mandale, located by modern border marker 9, to the Col d'Ibardin, a journey of 4¼ hr. The col is a popular spot for French shoppers due to cheap alcohol and tobacco. The trail continues via Col des Poiriers and Col des Joncs before reaching 43.336-1.66612 Olhette.

The steepest climb comes right at the beginning. For most of the route, you'll be on forest trails and, after Sare, quiet paved country roads. The trail initially ascends on a good path to the Col des Trois Fontaines, a journey of 1½ hr. A shelter is located 300 m from the col. The path then descends to the Col de St-Ignace, where the valley station of the cog railway to La Rhune is found. It continues to 43.312778-1.5802783 Sare, bringing the total walking time to 2¾ hr. Sare is a local transport hub, an outdoor swimming pool is available, and it is listed as one of Les Plus Beaux Villages de France. The stage ends in 43.306667-1.4986114 Ainhoa , which is also one of Les Plus Beaux Villages de France.

From Col des Trois Fontaines you can ascend La Rhune, which has an altitude of 905 m. The ascent can be made either by cog railway, a trip that takes 35 minutes, or on foot. The walk is a 3 km journey that takes 1¼ hr and involves an ascent and descent of 300 m. The prehistoric 43.2683-1.571394 Grottes de Sare can be visited with prior reservation made through the local municipality or online. These caves are closed annually for one month following Epiphany. This stage is part of the European long-distance trail E9.

This is a difficult stage, with little shade at the start and a particularly steep, rocky descent near the end. After about 40 minutes, you will reach the old cemetery at an altitude of 389 m. It is located beside the 43.303339-1.4823835 Chapelle Notre Dame de l'Aubépine. You can also find traditional Basque hilarri gravestones here. The path then continues over the Col des Trois-Croix, reaching an altitude of 510 m after about 1½ hr from the start.

Ferme Esteben is a good place to rest. You will reach this gîte d'étape with a bar-restaurant after about 3 hr, at an altitude of 580 m. The trail continues near the border, past Boundary Stone 77, partly on a paved road. At Col des Veaux, at an altitude of 550 m, you can take a 300-m detour into Spain to visit a venta, which is a small inn or shop. From here, the trail climbs to the Col de Méhatche, which is at an altitude of 716 m and takes about 3¾ hr to reach. The descent past Boundary Stones 82 and 83 is secured with cables. From Col de Méhatche, you can ascend Artzamendi, which has a summit at 926 m and is easily identified by the radar dome on top. The nearby 43.26526-1.389046 Grotte le Saint-que-Sue can also be visited.

Just before reaching 43.266667-1.3455 Bidarray, a bypass trail offers a shortcut to the next stage. This route is also ideal for peak baggers, as it gives access to several summits. These include Errebi, located between the chapel and Col des Trois-Croix, and Atxulegi, which requires a 15-minute detour on the way to Col des Trois-Croix. When the weather is good, you can also access Mont Bizkayluze at 701 m and Gorospil at 691 m.

This southward stage is demanding, especially due to the complete lack of water sources along the ascent. After passing the Iparla Ridge at an altitude of 950 m, the trail reaches over 1000 m for the first time on the way to the summit. It then continues along the ridge to the Pic de Tutulia before descending to the Col d'Harrieta. This point is reached after 3¾ hr and sits at an altitude of 808 m.

The main trail continues across the Buztanzelhay summit, which is reached in 4¾ hr at an altitude of 1029 m. The trail then leads down to the col of the same name at 843 m. Here, the GR-10 turns left and descends steeply. The path crosses the D949 road several times; this road leads from the village to the ventas on the Spanish border at the Col d'Ispéguy. You can also reach this col via the ridge, a distance of 1½ km from Col Buztanzelhay.

If you want to skip entering 43.175-1.3463896 Saint-Étienne-de-Baïgorry, a village situated at 162 m, you can join the next stage earlier at the Nive des Aldudes. This location can be reached in 6½ hr and is at an altitude of 162 m. In the village park, there is a picnic area, and a supermarket stocks gas cartridges. Locals play Rebot, a type of pelota, on two courts. The Château d'Etxauz is not open to the public. The village hosts a traditional folklore festival known as Nafarroaren Eguna on the last Sunday in April. The Nive des Aldudes valley occasionally experiences flooding and mudslides.

This stage runs mostly on gravel paths and farm tracks. About an hour into the walk, there is an optional detour at Col d'Aharza for a 35-minute climb to Oylarandoy, where a hermitage built in 1706 stands. The GR-10 heads south to the Col d'Aharza, which is at an altitude of 734 m and reached in 2 hr. A water source is available at the col. The trail then turns east and circles around 43.142148-1.307057 Munhoa. This summit is at 1023 m and is reached after a total of 3½ hr. The climb is fully exposed to the sun. The descent begins on the right-hand side. 43.163222-1.2381117 Saint-Jean-Pied-de-Port lies at an altitude of 170 m and is where three of the four French pilgrimage routes converge before entering Spain. From here, it is possible to continue directly onto the Camino de Santiago towards Roncesvalles.

There are no supply points or public transport on this stage, but the walking is relatively easy. In the village of 43.1475-1.21758 Çaro , at an altitude of 242 m, there is a public fountain next to the town hall. If you choose to end the day early after 3¾ hr in 43.104444-1.1955569 Estérençuby , be aware that this adds an extra 400 m of ascent to the next day's stage. The village lies at an altitude of 231 m and offers two accommodation options.

This stage is simple but offers little shade. The trail first climbs toward the Col on Ithurramburu, which is at an altitude of 820 m. It then continues ascending to just below 43.0344-1.106948 Occabe at 1456 m. On the Occabe plateau, 26 Neolithic stone circles have been found. Known as harrespil in Basque, they are believed to have been used for cremation rites. A good rest stop, reached after 4¾ hr, is the upscale 43.037117-1.07515410 Iraty Sorho. Across the stream at Le Kayolar, similar accommodation is available. From here, the trail turns sharply right after 100 m and continues uphill for another 6-7 km to the stage destination, a final ascent of 300 m.

In bad weather, the route along the west side of the 43.054722-1.0269449 Pic des Escaliers, which has an altitude of 1423 m, is not recommended. There are two alternative routes, but both are poorly marked. At the Ugatzé Ridge, the trail skirts the peak rather than summiting it. To avoid the steep descent from Pic des Escaliers, stay on the road for about 600 m after the start, then turn off after 2½ km to reach Col Ugatzé. A short side trip allows you to summit Arthanolatzégagnia, which requires an additional 35 minutes for the ascent and descent.

For several hr, trail markings are sparse. After some time following mule tracks, you'll reach a road crossing at Beloscare, which is at an altitude of 1173 m and is reached after 3 hr. 43.018172-0.9277361 Auberge Logibar marks the end of the stage, but you can also continue 2 km further to 43.018611-0.95583311 Larrau, which offers three accommodation options and a campground. In bad weather, an easier alternative is to follow the paved road from Iraty directly to Larrau for a gentler descent.

This stage leads through spectacular gorges. Follow signs to the Gorges d'Holzarté and ascend the trail to the 70 m long suspension bridge, a walk of 50 minutes. The bridge spans the dramatic Ruisseau de Olhadubi gorge 150 m above the ground. On the far side, the trail continues uphill.

After 2 hr, you reach the Olhadubi stream, which is a possible spot for a refreshing dip. Nearby is the 42.98857-0.904832 Cayolar d'Olhadubi, reached via a side path from the bridge. It serves as an emergency shelter with space for 4-5 people. Continuing uphill, you'll reach the Abarrakia farm after just over 3 hr. The path then winds between farms, eventually reaching the point where the GR-10 turns sharply to the right, a journey of 4½ hr from the start.

After about 5 hr, you'll reach the Col d'Anhaou at an altitude of 1383 m. From here, energetic hikers can summit nearby peaks such as Izeyto at 1464 m or Sarimendi at 1484 m. The stage ends at 42.99567-0.8110112 Sainte-Engrâce. Sainte-Engrâce is home to a Romanesque church from the 11th century. From the village, a 9-km side trip with an ascent of 840 m and descent of 135 m takes you to the vast La Verna cave, which has guided tours. A detour south from the restaurant leads into the wild and romantic Gorges de Kakuetta. The trail is known to be very steep and slippery in places.

The trail climbs steadily from Sainte-Engrâce into the limestone highlands of the Pierre-Saint-Martin massif, marking the transition into more alpine terrain. You ascend to the Col de la Pierre-St-Martin at an altitude of 1760 m, which marks the border with Spain. Since 1373, the Tributo de las Tres Vacas, a cross-border tribute of three cows, has been held here every July 13 to settle grazing rights between the two valleys. A small shop at the parking area sells goat cheese. A ski area lies just over the border on the Spanish side. There is also a small shelter near Boundary Marker 62.

An optional 15-minute detour leads to the summit of Soum de Lèche, which has an altitude of 1839 m. The Grotte de la Verna, a massive cave chamber accessible by pre-booked guided tour, lies 1 km off the main trail. From the pass, descend to the first switchback, then turn right off the main track. The trail passes under two chairlifts and continues along the northern flank of the Pic d'Arlas. When you spot three large concrete water tanks, descend to 42.9778-0.74473613 La Pierre Saint-Martin.

This is a challenging stage, but the scenery is magnificent. Several rocky mountain paths are equipped with cables for safety. The highest point is the Pas de l'Osque at an altitude of 1922 m, which requires a head for heights. The trail continues to the Pas d'Azuns at 1873 m, reached in about 2¾ hr. A good first rest stop with water is the spring near the 42.958821-0.7052173 Cabane du Cap de la Baitch, located at 1689 m and reached after about 3 hr. In wet weather, descending to 42.933889-0.63472214 Lescun at an altitude of 895 m via the road is recommended, as the GR-10 becomes muddy and difficult to navigate.

The trail begins easily through pastoral countryside, then enters forested terrain, passing the 42.911349-0.6191194 Cottage and camping Accous Lhers-Lescun after about 2 hr. It continues climbing to the Col de Barrancq at 1601 m, a journey of roughly 3¾ hr. From the col, a side trip leads to the summit of Pic de Labigouer at 2175 m, which is a 3 hr round trip.

Lower down in the Parc d'Orce, within the commune of 42.909167-0.57277815 Borçe , reached in about 5¾ hr, lives the majority of the region's approximately 50 brown bears. The stage ends in 42.9125-0.57027816 Etsaut , at an altitude of 597 m. This village is located on the N-134 and is served by the Canfranc-Oloron-Sainte-Marie bus line. Its former train station now houses the Pyrenees National Park visitor center. Just outside Etsaut, the 42.886389-0.56277810 Fort du Portalet clings dramatically to the cliffs in two tiers, spanning a height difference of 150 m.

The trail begins with the dramatic Chemin de la Mâture, a path carved directly into the rock face which is not passable in icy or snowy conditions. After about 2 hr, the route reaches Grange Perry at an altitude of 1210 m. Shortly after, hikers should keep to the left path. The trail continues to the 42.87832-0.5074935 Cabane de la Baigt de Saint-Cours at 1560 m, a shelter reserved for shepherds from June to September, arriving after about 3½ hr at the border. Approximately 4 hr into the hike, you will cross a stream on a bridge, which serves as the last reliable water source before the high pass.

The highest point of the stage is the Col d'Ayous, reached at an elevation of 2185 m after 5½ hr or more. On its eastern slope lie the scenic Ayous Lakes and the 42.84833-0.490966 Refuge d'Ayous, an ideal place to break this long stage. The Col d'Ayous also marks a significant transition point between valleys, leading from the Chemin de la Mâture and Baigt de Sencours in the Aspe Valley down to Bious-Artigues at 1540 m in the Ossau Valley. This area, located 6.5 km from the pass with a descent of 764 m, offers pony rides and canoe rentals on the eastern shore of the lake.

From the pass, several options are available. One can summit Pic d'Ayous, which adds about 30 minutes for the ascent and descent. Alternatively, a 6 km detour leads to Lac Bersau, with a longer 9 km alternative possible via the Vallon d'Aas. From the lake, the descent follows the D231 road, which features switchbacks that can be shortcut. Please note that the Refuge de Gabas is permanently closed. The stage concludes in 42.889764-0.42785817 Gabas . The village offers two accommodations and a bar, but it does not have a grocery store. Gabas is situated on the 806/806bis bus route, which runs from Col de Portalet to Laruns, a distance of 15 km.

This is a long and difficult stage where water is scarce and a head for heights is required for the Corniche des Alhas section. Snow may linger on the trail well into summer, which can make following the waymarks challenging. The trail begins by following the D934 road to the Artouste dam before climbing through forest paths. Some parts of this route, known as the Corniche des Alhas, traverse ledges carved into the cliff-side, which are equipped with fixed cables for safety.

The path reaches a bridge near the Gave de Soussouéou waterfalls at an elevation of 1145 m. From here, a steep trail leads up to Houn de Mouscabarous at 1361 m and continues its ascent to Petite Arcizette at 2293 m. Snow can persist at these elevations until July. The route then brings you to the Hourquette d'Arre at 2465 m. It is important to note that the path shown on some maps leading to the Géougue d'Arre at 2619 m is a mountaineering route and not a standard hiking trail. The GR10 does not go directly to Lac d'Uzious. Instead, it heads in a roughly north-northeasterly direction across a plateau before turning east to begin its descent. You will eventually reach Lac d'Anglas, situated at 2068 m. From the lake, the trail continues along its outflow before branching off to the right.

The stage concludes in the ski resort of 42.958056-0.33222218 Gourette , located at an altitude of 1350 m. The resort has two supermarkets, and gas cartridges are available for purchase at Intersport. Travelers should be aware that Gourette is mostly closed outside of the main tourist season. During the season, it is served by Bus 806, which runs from Parking Gourette Nord to Eaux-Bonnes, Laruns, and Pau.

This is a relatively easy stage that crosses two mountain passes. The first is the Col de Tortes at an elevation of 1799 m, reached after about 1¾ hr. Later, after crossing the D918, a road popular with cyclists but too busy to follow safely, the trail reaches the Col de Saucède at 1525 m after approximately 3 hr and twenty minutes. From Col de Saucède, hikers can also make a short detour to the summit of Pointe de Surgatte at 1805 m, a round trip that takes between 90 and 100 minutes.

Near the Pont de Lapadé, you have the option to either cross the Gave d'Arrens or continue down into the village of 42.955556-0.21305619 Arrens-Marsous . The village provides tourist information and public toilets at the Maison Val d'Azun, which can be contacted at +33 5 62 97 49 49. Arrens-Marsous also features an outdoor swimming pool and hosts Eldorado, a hiking festival held for four days in late May every two years.

Points of interest in the area include the Romanesque Saint-Pierre Church, with parts dating back to the year 1200, and the Chapelle Notre-Dame de Pouey-Laün, a pilgrimage chapel located 600 meters south along the D105. The entire area is part of both the Natura 2000 conservation network, specifically the Gabizos and the Arrens Valley sites, and lies within the core zone of the Pyrenees National Park.

From Arrens-Marsous, located 3.5 km from the previous endpoint, hikers can choose between two routes: the official GR10 or the more scenic GR de Pays Tour du Val d'Azun. The latter option is slightly shorter but involves more climbing. Both trails rejoin shortly before reaching the 42.922-0.18197 Gîte d'étape les Viellettes, after about 2¼ of hiking. Approximately 700 meters further on is the simple tent site, La Pose, which is open from May to September. The official GR10 route passes through 42.937222-0.17916720 Estaing . The commune includes the three Natura 2000 protected areas of Gaves de Pau et de Cauterets, Moun Né de Cauterets; Pic de Cabaliros; and Péguère, Barbat, Cambalès.

From Estaing, the trail officially enters the core zone of the Pyrenees National Park. The path then ascends toward Lac d'Estaing. From the lake, the trail climbs steeply through a forest to the 42.89975-0.205058 Cabane Arriousec at 1400 m, a journey of about 4 hr. Another hour of uphill hiking takes you past the 42.881364-0.1988369 Cabane Barbat, which are located to the left of the path. A final climb brings you to the Col d'Ilhéou at an elevation of 2242 m, reached after 6 hr or more.

Just five minutes below the pass, an alternative route becomes available. By turning left, you can reach the Crête du Lys, where the Courbet cable car operates during July and August. This provides access to the Cauterets-Le Lys ski resort, which features a summer luge track, or offers a direct descent into the town of Cauterets. To continue on foot, descend from the col to the stream near the 42.878118-0.18061510 Cabanes de Arras, a walk of six and a half to seven hr. At this point, turn right and cross two more streams. The path then descends to Lac d'Ilhéou. On the lake's northern shore is the staffed 42.86623-0.17373811 Refuge d'Ilhéou. A designated bivouac area, or *aire de bivouac*, is located about ten minutes further south along the lake.

This is a leisurely downhill walk that brings you gently back to civilization in 42.889167-0.11361121 Cauterets . Cauterets flourished during the late 19th and early 20th centuries thanks to its thermal springs. The municipality operates two spas: Thermes de César in the village center and Thermes des Griffons in nearby La Raillère.

This demanding stage begins in Cauterets by taking the path located behind the Thermes de César and heading south. After approximately 1¼ hr, you will reach the hamlet of La Raillère, situated at an altitude of 1044 m. This small settlement offers restaurants and a sulfur spa. From La Raillère, cross the bridge and continue your ascent into the Val de Jéret, a scenic valley section where you will pass several waterfalls. After about 3 hr from the start, the trail leads to the Hôtellerie du Pont d'Espagne. From this point, descend briefly along the road before turning right to begin the climb into the valley that leads towards Lac de Gaube. The lake, at an elevation of 1725 m, is reached after a total of 4 hr. As you continue from the lake toward 42.79269-0.1413212 Refuge des Oulètes de Gaube, the path crosses the stream three times via bridges.

About 50 meters from the refuge, the trail embarks on a steady 1 hr climb over rocky terrain. After about 65 minutes, you will reach a fork where you should stay to the right and continue ascending. The trail reaches the Hourquette d'Ossoue, which at 2734 m marks the highest point on the entire GR10. Even in mid-summer, snow often lingers in this area. A 20-minute descent from the pass leads to the 42.77928-0.1241313 Refuge Baysselance. From here, attempting an ascent of Vignemale via the Glacier d'Ossoue is an undertaking suitable only for experienced mountaineers.

From the pass, the route heads south-east, passing the Grottes de Bellevue at 2420 m after about 3 hr. These are artificial caves carved in 1880 by the explorer Henry Russell. The trail then descends steeply to a stream and follows it into a boulder field fed by glacial melt from the Glacier d'Ossoue. The descent into the valley is challenging, involving frequent climbs around cliffs and waterfalls. After 5 hr or more, you enter the Vallée de la Canau and pass the 42.738676-0.07209814 Cabane Sausse Dessus. The next hour continues with more ups and downs until you reach the 42.741556-0.0380515 Cabane des Tousaus after a total of 6¾ hr.

From there, cross a final ridge to reach the D923 road and then descend to the stage endpoint at the Chalet-refuge la Grange de Holle. If you require more extensive accommodation or supplies, continue to the main village of 42.732222-0.00944422 Gavarnie. From Gavarnie, you can take a popular day trip into the famed Cirque de Gavarnie, which is also accessible by bus from Luz-Saint-Sauveur. For experienced climbers, it is also possible to ascend Le Taillon, which stands at 3146 m, from this area.

The GR 10 is a demanding high-mountain route that requires careful preparation and self-sufficiency. A primary consideration is the weather in the Pyrenees, which can change with extreme speed, bringing thunderstorms, high winds, and dense fog, often in the afternoon. Furthermore, snow can linger on high cols well into July, obscuring the path and making navigation difficult. Therefore, carrying a map, compass, and a GPS device is essential, as official waymarking can be inconsistent or hidden by snow.

Hikers must also manage their resources carefully. Water can be scarce on some long stages or at high elevation, particularly in the eastern section, so it is wise to carry more than you expect to need. All water from natural sources should be treated, especially in pastoral areas with livestock. Encounters with wildlife also require awareness. The most common issue involves Patous, the large Pyrenean Mountain Dogs used to guard sheep. These are working animals, not pets, so it is crucial to give them and their flocks a wide berth, walking calmly to avoid provoking a defensive reaction. Vipers are also present, so watch your step in rocky, sunny areas, while the reintroduced brown bears are elusive and pose a negligible risk.

In case of an emergency, the pan-European number is ☏ 112. However, mobile phone coverage is unreliable in many parts of the mountains. For this reason, carrying a personal locator beacon (PLB) is recommended for safety. As a basic precaution, always inform someone of your daily itinerary before you set out.
