Illustrative artwork — an impression of Cares Gorge — Picos de Europa, not a literal photograph.
The Ruta del Cares is a roughly 12-kilometer path carved into the limestone cliffs of the Picos de Europa, running one way between the villages of Poncebos in Asturias and Caín in León. The trail itself is mostly level, but it clings to a ledge high above the Cares river, complete with tunnels and drop-offs, so most of the planning here is less about elevation and more about where you sleep and how you get back to where you started.
Why hike here
What makes the Cares Gorge memorable is the trail's construction itself — a path blasted straight into the rock face, sometimes ducking through unlit tunnels, sometimes opening onto a bare ledge with the river a long way straight down. You spend most of the walk somewhere between the cliff wall on one side and open air on the other, watching the Cares river carve through the gorge in shades of green and white far below. The one-way layout adds to the feeling of a real journey rather than a loop: you start in Asturias and finish in León, crossing an invisible regional line partway through, with the character of the villages shifting from one end to the other. It's a walk that rewards a steady head for exposure and unhurried footwork rather than raw fitness.
Getting there
Most hikers set up in Arenas de Cabrales or one of the small towns near the Asturias end of the gorge, since that side has the most lodging choices, then arrange a taxi or bus to the trailhead at Poncebos. There's no airport near the gorge itself — the realistic route is to fly into the nearest international or regional airport in northern Spain, then connect by train or bus toward Asturias or León and finish the trip by car or local bus. Because the walk is one-way, transport to the far end at Caín, or back again, needs planning before you start.

No permit is needed. The path is a spectacular ledge cut into the cliffs high above the river — mostly level but exposed, with tunnels and drops, so keep back from the edge, carry water and sun protection, and mind the many day walkers in summer.

Common questions
Do I need a permit to hike the Cares Gorge?
No — the Ruta del Cares does not require a permit, so you can start whenever you like. Because it's a narrow, exposed ledge route that gets busy, especially in summer, most hikers still aim for an early start, both to beat the heat and to move through the tunnels and tighter sections before the crowds build up.
Since the trail is one-way, how do most people handle getting back?
Some hikers walk out and back from the same end, turning around partway or at Caín before returning to Poncebos. Others arrange transport — a taxi, bus, or a second car left at the far end — so they can walk the full one-way distance without retracing their steps. Either way, it's worth deciding before you set off, since options at the Caín end are more limited.
Where should I stay the night before hiking the gorge?
For an early start, look at hotels and guesthouses right at the trailheads in Poncebos or Caín. If those are full or you want more choice, nearby towns such as Arenas de Cabrales have a wider range of hotels, guesthouses, and casas rurales, usually a short drive from the gorge itself.
