The Picos de Europa are fairly well served by mountain refuges, most being wardened just in the summer months.
Supplementing the services provided by these refuges are many small, basic shepherd's huts dotted all over the mountains. Don't expect much from these though apart from a roof and walls.
Discounts on the refuge rates are available for card-carrying international mountaineering club members. You should book bunk spaces and meals in advance online here
Some huts are easily accessible by well-marked paths, some routes require mountaineering skills.
We've separated the huts into their respective massifs (see below) and have added location maps. The google maps are meant as a rough guide only as they're not 100% accurate. Use the + tool to zoom in on them first then click and drag the maps.
