The Sentier du Littoral is a premier 25km coastal hike in the Pyrénées-Atlantiques, linking Bidart to Hendaye along the Atlantic cliffs.
This route follows the GR8 trail in sections, passing through the historic corsair port of Saint-Jean-de-Luz and near the iconic Château d'Abbadia.
The most dramatic segment is the Corniche Basque, where the path sits atop sheer cliffs with views of the Pyrenean foothills and the Bay of Biscay.
Well-connected by the local TER Nouvelle-Aquitaine train line, the hike is highly accessible for those seeking a mix of nature and Basque village culture.
The path features a series of moderate climbs and descents as it transitions from the surf breaks of Guéthary to the wide bay of Hendaye.
Overview
Technical Summary
The Sentier du Littoral (Coastal Path) is a classic 25km traverse of the French Basque coastline, stretching from the surfing village of Bidart down to Hendaye on the Spanish border. This route offers a continuous panorama of the Atlantic Ocean and the unique flysch rock formations.
The Basque Corniche. The 'X-Factor' is the dramatic middle section between Ciboure and Hendaye, known as the Corniche Basque. The trail clings to the high, grassy lip of colossal, crumbling slate-grey cliffs. Looking down, the massive Atlantic swells smash sustainedly into the jagged reef below. Looking left, you see the iconic, mythical peak of La Rhune acting as the gateway to the Pyrenees.
Hazard Assessment
The Basque coast is geologically active; cliff edges can be unstable, particularly after heavy rainfall. Sections of the path along the Corniche Basque may be rerouted inland due to erosion.
The Bay of Biscay is known for rapid weather shifts; conditions can feel more exposed during coastal storms with strong winds.
The Expert Take
Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.
Stage Breakdowns
Bidart to Saint-Jean-de-Luz
Starting at Uhabia beach, crossing grassy headlands, passing spectacular surf breaks like Guéthary, and descending into the historic corsair port of Saint-Jean-de-Luz.
Saint-Jean-de-Luz to Ciboure
A very flat, urban link crossing the bridge over the Nivelle river and walking through the beautiful harbour town.
The Corniche to Hendaye
The wildest section. Climbing up onto the high, sheer cliffs of the Corniche, passing Abbadia Castle, and descending finally to the massive 3km beach of Hendaye.

Technical Profile
Vertical Ascent Profile
An endless series of 'bite-sized' climbs and drops. While you never exceed 80 meters in absolute altitude, you are constantly dropping from high grassy headlands down to sea-level beaches, and immediately climbing steep, calf-burning stairs back up to the next cliff. The cumulative elevation gain of 650m over 25km makes it surprisingly tiring.
Terrain Characteristics
Coastal Trail (Class 1) — established paths and promenade walking with no technical scrambling or specialized skills required.
A measured physical load of 650m ascent requires steady pacing but remains accessible for active hikers.

Access & Logistics
Regulations
No permits. Follow the yellow markers. Bivouacking is generally forbidden on the beaches and cliff tops; use the official campsites.
Seasonality
Accessible year-round. July and August can be very crowded with high temperatures; May, June, September, and October offer the best balance of weather and crowd levels.

Route Questions
Can I do it in one day?
Yes, incredibly fit hikers can push through the 25km and 650m elevation in about 7 hours. However, it is much better enjoyed over two days, allowing time to swim, eat seafood, and soak in the Basque culture.
