More ways to explore the area's outdoor wonders
You step off the coach into thin mountain air and the Picos de Europa greets you with a blunt, limestone edge; the road has already climbed from the sea and the lakes lie like two quiet mirrors in a high bowl. The guide gestures toward Enol and Ercina and the story of ice and stone that shaped them unspools as you walk the short, rocky shore: glaciers gouged hollows; runoff collected and now the lakes reflect the peaks above.

Layer for variable mountain weather
Temperatures can fall quickly above 1,000 m—bring a warm mid-layer and a waterproof shell you can stow in a daypack.
Wear sturdy shoes
Short walks around the lakes include gravel and stone steps; hiking shoes or trail runners will keep traction on wet rock.
Carry small change
Local taverns and cider bars in Cangas de Onís may prefer cash for quick purchases and tapas.
Start early or late for light
If you want quieter viewpoints and softer light on the lakes, aim for morning or late afternoon; mid-day is busiest.
Waterproof jacket
Protects against sudden mountain rain and wind common in the Picos.
Sturdy trail shoes
Provides grip on gravel paths, wet stone, and uneven shores around the lakes.
Daypack with water bottle
Carry layers, snacks, and 1–2 liters of water for the day trip.
Lightweight binoculars or camera
Useful for spotting chamois, birds and capturing the wide limestone ridges and lake reflections.
