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.
