How to Hike the Picos de Europa
Welcome to the complete guide to hiking the Picos de Europa — one of Spain's most dramatic and underrated mountain ranges. Drawing from my own recent traverse of the range, this guide covers day-by-day routes, essential logistics, trail conditions, wildlife, and the cultural magic hiding in stone villages along the way.

Overview
The Picos de Europa straddle three Spanish regions — Asturias, Cantabria, and Castile and León — packed into a compact massif that punches far above its size. Towering limestone towers, glacial lakes, chamois-dotted ridges, and medieval pilgrimage villages make this one of Europe's finest mountain experiences.
This route combines the classic Ruta de la Reconquista with the high-level traverse of the Central Massif, dipping into the famous Cares Gorge and finishing with an ascent to the base of Naranjo de Bulnes — the iconic orange rock spire that defines the range.
🏔 The essential experience
The Cares Gorge — 12 km of narrow path carved into a sheer limestone canyon, 1,000 m above the river — is arguably the most spectacular trail in all of Spain. Don't miss it.
Essential Information
Getting There
Fly into Santander (SDR) or Oviedo (OVD). Both airports are under 2 hours by car or bus to the trailheads at Potes (eastern access) or Cangas de Onís (western access). The ALSA bus network connects most villages, though having a car opens up far more of the range.
Accommodation
The Picos has a solid network of refugios (mountain huts) and rural guesthouses. Most offer half-board (dinner + breakfast) for around €35–50pp. Book ahead for July and August. Outside peak season, walk-ins are usually fine.
Difficulty & Fitness
The main trails are well-marked and don't require technical climbing, but the terrain is consistently steep and rocky. Daily elevation gains of 600–1,200 m are normal. Prior multi-day hiking experience is strongly recommended.
Day-by-Day Itinerary
This 12-day route begins in Potes and finishes in Cangas de Onís, crossing the range west to east with optional extensions to the high summits.

Trail Highlights
- Cares Gorge — 12 km path carved into vertical limestone; the defining Picos experience.
- Naranjo de Bulnes (Picu Urriellu) — Iconic 2,519 m spire. The approach hike alone is worth it.
- Fuente Dé cable car plateau — Step onto the high massif in 4 minutes and walk above the clouds.
- Chamois and griffon vultures — Wildlife encounters are virtually guaranteed on any ridge walk.
- Sotres & Bulnes — Remote villages with no road access, subsistence farming, extraordinary cheese.
- Covadonga Sacred Lakes — Glacial tarns beneath the peaks where Spain's nationhood is said to have begun.

Best Time to Go
The Picos sit right against the Atlantic, which means unpredictable weather year-round. The mountains catch moisture rolling in off the Bay of Biscay, keeping the vegetation impossibly green — and the trails occasionally wet.
June and September are the sweet spots: stable weather, fewer crowds than July–August, wildflowers in June and golden autumn colour in September. July–August sees the refugios packed and trails busiest along the Cares Gorge. October–November can be magic if you're lucky with the weather — the beech forests turn copper and the gorge is quiet.
Snow on the high plateau is possible October through May. Always check conditions at Fuente Dé before heading up to the ridge.
