About This Route
The Picos de Europa Loop takes you through one of Spain's most dramatic mountain landscapes. This national park features jagged limestone peaks, deep gorges, and traditional villages that seem frozen in time. The route winds through the Cares Gorge area and offers stunning views of peaks reaching over 2,600 meters.
Route plan
- Cangas de Onís to Arenas de CabralesFollow the AS-114 east as the broad valley tightens toward the limestone wall of the Picos. Arenas is the sensible first coffee stop and the gateway to Cabrales country.
- Arenas to PotesContinue through Panes and take the N-621 through Desfiladero de La Hermida. The road runs between near-vertical gorge walls, with short sight lines and several places where stopping is unsafe.
- Potes to RiañoThe N-621 climbs away from Liébana toward Puerto de San Glorio before dropping to the reservoir at Riaño. This is the highest, most exposed part of the day and the first section to feel wintry outside summer.
- Riaño back to Cangas de OnísReturn north on the N-625 through the Desfiladero de los Beyos. It is a long final leg, so refuel in Riaño and leave enough daylight for the shaded gorge.
What the road is really like
This is not a loop of continuous hairpins. Its appeal comes from contrast: open reservoir roads, two enclosed limestone gorges, high pasture and compact village sections. The surface is generally paved and suitable for touring bikes, but damp shade, fallen rock and livestock can change the pace quickly.
The N-621 through La Hermida is the most visually dramatic section, yet it demands restraint because lay-bys are limited and oncoming traffic can cut close to the centre line. The N-625 through Los Beyos feels quieter and more remote; fatigue is a bigger concern there than outright technical difficulty.
Planning the day
Treat 210 km as a full riding day rather than a five-hour dash. Coffee, viewpoints and lunch easily turn it into seven or eight hours. Cangas de Onís, Potes and Riaño are the dependable service points; do not assume fuel in the smaller hamlets.
The Covadonga Lakes are an optional excursion, not a through-road. In 2026 private motorcycles are barred during published peak dates, including most of June to mid-October, and access switches to bus or authorised transport. Check the official access calendar before adding the spur.
Fuel, food and stops
Reliable fuel options along or near the route include Cangas de Onís, Potes. Top up before any long climb — pumps in mountain villages can be closed at lunch or on Sundays.
For food and coffee, Arenas de Cabrales, Fuente Dé are solid stops. Aim for a proper sit-down lunch rather than a vending-machine snack — the locals eat well in this region.
⚠️ Safety and hazards to watch for
Specific hazards on this route include: Fog in mountains; Loose gravel.
- Narrow mountain roads
- Watch for livestock
- The Covadonga lakes leg is closed to private cars and motorcycles for most of the summer season (mandatory paid shuttle), and the high passes (San Glorio, Pandetrave) can be snowbound Nov–Apr — check current conditions.
Who this route suits
Picos de Europa Loop works especially well for photographers and slow-tour riders chasing scenery, adventure bike riders who don't mind the occasional rough patch. Recommended bike types are Touring, Adventure, but realistically anything in good mechanical condition with decent tyres will do the job — the road matters more than the badge on the tank.
