Aizkorri-Aratz Natural Park
Route 5 Vitoria-Gasteiz / Alegría-Dulantzi / Araia
Shared between Álava and Gipuzkoa, the Aizkorri-Aratz Natural Park comprises a set of mountain ranges, dominated mostly by limestone rocks, where the highest peaks of both territories are located.
It is also famous for places such as the La Leze ravine-cave, a large 80 metre high cavity, unique in Europe due to its geological characteristics and a veritable paradise for lovers of canyoning.
Equally as impressive is the San Adrián tunnel, a natural passage between Álava and Gipuzkoa that passes through rock and located in a spectacular setting.
