GR 11

A classic Pyrenees thru-hike on the Spanish side, built around long days, frequent climbs and multi-day gaps between full resupply.

Time to Hike: Most fit walkers take about 44 days, but itineraries vary widely depending on pack weight, weather windows and how often you stop in towns.

Best Time to Go: Mid-summer to early autumn is the usual window for high passes, with more reliable hut openings. Early season can mean lingering snow on higher ground.

Getting there: The west end is at Cape Higuer near Irun in the Basque Country. The east end is at Cap de Creus in Catalonia, reached via the Figueres area and coastal buses/taxis.

Costs: Costs depend on how often you sleep in staffed refuges or use hotels in valley towns versus carrying a tent and cooking. Budget more for food in remote areas where you carry 3-4 days of supplies.

Difficulty: Hard. Expect many steep ascents and descents as the route repeatedly crosses valleys, with some days around 1,600 m of ascent (and similar descent).

The GR 11 (also known in Spain as the ruta Transpirenaica) is part of the long-running GR footpath network and traverses the Spanish side of the Pyrenees. From west to east it links Cape Higuer on the Atlantic to Cap de Creus on the Mediterranean, crossing Navarre and Aragon before finishing in Catalonia.

Its character is defined by geography: because most rivers run perpendicular to the trail, the GR 11 repeatedly climbs out of one valley and drops into the next. That means big viewpoints and a constant rhythm of passes, ridgelines and long descents, with a total elevation change of about 39,000 m over roughly 840 km.

The trail is traditionally described in 45 sections, each normally ending at a practical stopping point such as a camping spot, town, hostel or mountain refuge. It only briefly enters France near Candanchu, but otherwise stays firmly on the Spanish side of the range.

• Stage 1: Cape Higuer to the western Navarre valleys (km 0-110) - A green, Atlantic-influenced start with frequent climbs and drops as you settle into the Pyrenean rhythm.
• Stage 2: Western Navarre to central Navarre (km 110-220) - A sequence of valley crossings where logistics start to matter - plan food carries around the next reliable town.
• Stage 3: Into Aragon and the Candanchu area (km 220-330) - Higher terrain and more sustained mountain walking, including the trail’s brief passage into France near Candanchu.
• Stage 4: Central Aragonese Pyrenees (km 330-450) - Big days of ascent and descent as the route traverses multiple valleys, with extensive views from higher crossings.
• Stage 5: High Aragon to the approach of Catalonia (km 450-570) - Remote-feeling stretches where you may need to carry 3-4 days of supplies between full resupplies.
• Stage 6: Western Catalan Pyrenees (km 570-670) - Hotter conditions are common here in summer, and the profile can feel steeper, making early starts useful.
• Stage 7: Central to eastern Catalan Pyrenees (km 670-770) - Long traverses between stopping points, with repeated climbs out of river valleys and broad mountain panoramas.
• Stage 8: Down to the Mediterranean at Cap de Creus (km 770-840) - The final push trends lower and drier as you leave high mountains behind and finish at the sea.

The practical season is when high ground is clear enough to travel safely and when mountain services are more likely to be operating, which generally centres on mid-summer through early autumn. Earlier in the year, lingering snow can make higher sections slower and more hazardous.

Heat is a key factor on the eastern and central parts of the route (the Catalan Pyrenees and Aragonese Pyrenees), where hotter days and steeper profiles can be physically demanding. Whichever direction you choose, plan for sun exposure and build in flexibility for storms in the mountains.

Most westbound starts are reached via Irun (linked by rail and buses), then local transport or a short transfer out to Cape Higuer. The nearest major international airports are typically around Bilbao and San Sebastian, depending on your preferred connections.

On the eastern end, finishing at Cap de Creus usually means heading back via the Figueres area for onward trains and connections toward Barcelona or Girona. The route can be walked in either direction, and many walkers choose direction based on heat, steepness and sun exposure.

Check local regulations; some protected areas or refuges may have restrictions or booking rules, so confirm whether any permits or reservations are required before you go. Logistics are more about planning resupplies and overnight stops than paperwork.

If you intend to sleep in staffed mountain refuges or specific campsites, you may need advance reservations depending on the location and the time of year. Check each refuge’s booking rules before you set your schedule.

Accommodation is typically a mix of mountain refuges, hostels and guesthouses in towns, plus camping where appropriate. The trail’s 45-section structure often aligns with natural stopping points, but you should still plan carefully for multi-day stretches without easy resupply.

In peak summer, popular refuges and beds in key valley towns can fill up, so booking ahead helps if you want a fixed itinerary. If you prefer maximum flexibility, carrying a tent lets you adapt your daily distances, but you still need to factor in local camping rules and weather exposure.
