Aizkorri Refuge and Hermitage

Highlight • Mountain Hut

The Aizkorri Free Refuge is located in one of the most visited ranges of the Basque Mountains, because it is home to Punta Aitxuri, the roof of Guipuzcoa

An essential for those of us who live around here, without wind (which rarely happens around there) it must be a joy to sit quietly to have a sandwich. Well, actually, in the hermitage there is a small bench that looks towards the Guipuzcoan side where the wind does not usually blow. Too bad he's always busy.

San Adrián Tunnel

Highlight • Cave

Curious formation that allows us to go from one side of the mountain to the other.
Be careful if it is wet or damp as the stones slip a lot.
