The other walk we did in the Picos de Europa was a circular route, starting and finishing at Fuente De.
We took the cable car up to the top of the plateau.
Then walked the PR-PNPE.24: Puerto de Áliva route.
Instead of heading all the way down to Espinama, we turned right along a fairly new track that took us back to Fuente De without walking along the road. Unfortunately, the heavens rather opened during this part of the walk.
