The GR10 is a monumental, 866km trans-Pyrenean thru-hike that traverses the entire length of the French Pyrenees, from the Atlantic coast at Hendaye to the Mediterranean at Banyuls-sur-Mer. Widely regarded as one of Europe's most demanding long-distance trails, it follows established paths through the high-mountain landscape, crossing numerous iconic passes and dipping into traditional mountain valleys. The journey typically requires 50 to 60 days of sustained effort and is known for its extreme physical attrition due to the constant vertical shifts between valley floors and high cols.

Mission Directive / X-Factor
“The Coast-to-Coast Progression. The 'X-Factor' is the comprehensive geographical accomplishment of crossing an entire mountain range from sea to sea. Starting at the Atlantic breakers and finishing in the Mediterranean surf after two months of movement creates a unique sense of scale. The route is often described as a reset of one's perspective on distance, as hikers witness the slow transition of landscape, architecture, and climate across the length of the Pyrenees.”
Hazard Assessment
Because the trail crosses the valleys rather than following a ridge, the total elevation gain is absurdly high—nearly 48,000 meters. The daily physical toll of climbing 1,000m and descending 1,000m for 50 days breaks many hikers.
MITIGATION: Do not rush. Schedule zero-days (rest days) every 7-10 days in the valley towns. Keep your base weight strenuously light.
The central section (around Gavarnie and Vignemale) features serious alpine weather, sudden thunderstorms, and early snow dumps in September.
MITIGATION: Always descend into the valleys if severe lightning is predicted. The lightning strike risk on the high Cols is severe.

PATHWAY
Pyrenees (Atlantic to Mediterranean) // trekking
The Basque Country (Pays Basque)
Atlantic start in Hendaye. Rolling green hills, traditional white-and-red villages, and the initial climb into the Pyrenean foothills.
The Central High Peaks
The high-alpine heart. Navigating the National Park, crossing the Hourquette d'Ossoue (2,734m), and passing the Cirque de Gavarnie.
The Wild Ariège
The most remote and strenuous section. Steep, isolated valleys, few resupply points, and challenging, rocky terrain.
Pyrénées-Orientales to the Sea
Entering the Catalan Pyrenees. Crossing the Canigou massif before dropping into the heat of the Mediterranean coast at Banyuls.

Technical Specifications
DOC_REF: GOLDEN_HIKING_FRANCE_017Refuge Capacity
A network of gîtes d'étape and staffed mountain refuges (refuges gardés) covers the route. In remote sections like the Ariège, unstaffed cabanes of varying quality are available. Carrying a tent is standard practice for flexibility.
Regulatory
- Permit NONE
- Authority Parc national des Pyrénées / FFRandonnée
No permits. Strict bivouac rules apply in the central National Park zone (tents only allowed 7 PM to 9 AM, 1 hour walk from roads).
Climatology
- OptimalJun, Jul, Aug, Sep
The optimal window is late June to late September. High passes like the Hourquette d'Ossoue can remain under dangerous snow until late June. Resupply is typically possible every 3-5 days in valley villages (e.g., Cauterets, Luz-Saint-Sauveur, Bagnères-de-Luchon). Target a base weight under 8kg to manage the 48,000m of ascent.
