Hiking the Pyrenees: GR10, GR11 & the HRP
The Pyrenees form the 430 km natural border between France and Spain, a wilder and less developed range than the Alps with a comparable density of great trekking. Three parallel long-distance trails — the GR10 on the French side, the GR11 on the Spanish side, and the Haute Route Pyrenees (HRP) along the watershed — offer a month of continuous high-level trekking.
The Pyrenees are quieter, greener on the Atlantic side, and more arid on the Mediterranean side, with a strong transhumance culture and excellent refuge network on both sides of the border.
This guide covers the three grand traverses, the refuge system, and the season window for high-level Pyrenean trekking.
GR10, GR11 and the HRP
The GR10 (~870 km, 40–50 days) traverses the French Pyrenees from the Atlantic to the Mediterranean, staying on the French side. It is more demanding than the GR11 in cumulative ascent, with longer, steeper days.
The GR11 (~820 km, 40–45 days) traverses the Spanish Pyrenees on the southern side. It is generally considered slightly easier than the GR10 with better waymarking and more frequent refuges.
The Haute Route Pyrenees (HRP, ~800 km) stays close to the watershed, crossing the border repeatedly and reaching higher, more remote terrain. It requires more navigation skill and is the choice for experienced trekkers seeking solitude.
Refuges and Access
Both sides have staffed refuges (refuges in France, refugios in Spain) with dormitory beds and meals, spaced roughly a day apart. Reserve in advance for August. Wild camping is permitted in many areas above the tree line, subject to local regulations.
Access is straightforward: the Atlantic end is reached via Hendaye/Biarritz, the Mediterranean end via Banyuls/Cap de Creus. Numerous valley towns along the range provide resupply and rest days.
Frequently asked questions
- How long is the GR10? Approximately 870 km across the French Pyrenees, typically walked in 40–50 days from the Atlantic to the Mediterranean.
- GR10 or GR11 — which is easier? The GR11 (Spanish side) is generally considered slightly easier, with better waymarking and more frequent refuges. The GR10 (French side) has more cumulative ascent and steeper days.
- When is the best time to hike the Pyrenees? June to September for the high-level routes. Snow can linger on high passes until early July. August is peak season; September is quieter and excellent.
- Do I need a guide for the Pyrenees? No. The GR10 and GR11 are well-waymarked. The HRP requires more navigation skill. Refuges should be booked in advance for August.
