The ascent of La Rhune (905m)—the sacred mountain of the Basque people—on foot from Sare village rewards hikers with a 360° panorama over the Basque coast, the Spanish Pyrenees, and the Atlantic Ocean. A rack railway also serves the summit.
La Rhune (905 m) is the iconic mountain of the French Basque Country, rising directly above the coastal villages of the Pyrénées-Atlantiques department of Nouvelle-Aquitaine to command a 360-degree panorama over the Bay of Biscay, the Pyrenean foothills, and the Franco-Spanish border. The Sentier du Rhun is the main foot trail ascending the mountain from the village of Sare; the 10-kilometre return route gains the full 905 metres from the valley floor and requires approximately 4 hours for the round trip. Sare is reached by car from Bayonne (30 km north) via the D918 and D306; parking is available at the Col de Saint-Ignace, where the historic Petit Train de la Rhune narrow-gauge rack railway also departs for the summit. The Col de Saint-Ignace trailhead at approximately 170 metres elevation provides the most direct starting point for the foot ascent. The trail is well signed and follows a clearly defined path marked on 1:25,000 IGN maps. The route climbs through gorse and heather moorland on south-facing open slopes before entering the rocky summit zone. The terrain is a good quality earth path in the lower section; above 600 metres the surface becomes rockier and some passages involve easy scrambling over exposed boulders. Wild Basque ponies (pottoks), a semi-feral breed that has inhabited the Basque mountains for millennia, roam freely across La Rhune's slopes and are one of the mountain's most distinctive features. The summit provides an unobstructed panorama: the Atlantic coast from the Landes dunes to the Spanish Basque headlands, the Pyrenean massifs of Navarra and Aragon, and on clear days the Cantabrian coast of northern Spain. The Petit Train de la Rhune, operating since 1924, offers an alternative descent for those who prefer not to retrace the rocky ascent on foot; advance booking in peak season is essential.

Tips for visiting
- Consider taking the foot trail up and the Petit Train de la Rhune down if tickets are available; the railway descent avoids the knee-straining rocky section and is a heritage attraction in its own right.
- Book Petit Train tickets well in advance for July and August; the train operates on a timed schedule and regularly sells out on busy summer days.
- The summit is exposed to strong Atlantic winds year-round; a warm windproof layer is essential even when the valley feels warm.
- Start the walk before 9:00 to reach the summit before the first train arrives and the terrace fills with day visitors.
- Do not approach or feed the pottok ponies; they are semi-wild and, though generally calm, can react unpredictably when crowded.
When to visit
May through October offers the most reliable foot-trail conditions; early morning starts in summer avoid the crowds arriving by train and the afternoon Atlantic cloud that often settles on the summit.
Accessibility
The Sentier du Rhun involves sustained steep climbing on rocky and uneven mountain paths and is not accessible for wheelchair users or strollers. Visitors with limited mobility can access the summit via the Petit Train de la Rhune rack railway departing from Col de Saint-Ignace; the summit terrace area is relatively level.
Frequently asked questions
Is the Petit Train de la Rhune a cable car?
No—the Petit Train de la Rhune is a narrow-gauge rack railway running on rails, not a cable car or gondola. It has operated since 1924 and is a heritage attraction in its own right; the ascent takes approximately 35 minutes.
Can La Rhune be climbed in winter?
La Rhune is climbable on foot in winter on clear days, though the upper rocky section can be icy from December to February and trekking poles or microspikes are recommended. The Petit Train operates on a reduced winter timetable.
Is the summit of La Rhune in France or Spain?
The summit sits exactly on the Franco-Spanish border. The majority of the approach trail on the Sentier du Rhun lies on the French side; the Spanish side has its own access trails from Bera (Vera de Bidasoa).
Are dogs permitted on the mountain?
Dogs are permitted on the foot trail but must be kept under control due to free-roaming pottok ponies and grazing livestock. Dogs are not permitted aboard the Petit Train de la Rhune.
