Besaide, an easily accessible place from Arrasate, Elorrio or Aramaiona, where the 3 Basque provinces meet, is a very emblematic place of Basque mountaineering, where on the third Sunday of September a commemorative act is celebrated in memory of all deceased mountaineers. We should have a little more awareness to preserve the clean environment.

If you climb from Araotz, follow the PR, and the climb is very easy and short. From the cave parking lot, it's much steeper and zigzags. About 2.5 or 3 km with a lot of elevation gain.
