Nice walk around the Kurtzeta reservoir. Cross the dam and don't forget to look out and enjoy the incredible views of Ganekogorta and Biderdi peaks, especially after the early season fresh snow cover.

Getting to the top of Biderdi is never easy, but it is very rewarding. The panoramic views from the summit at 900 meters above sea level are spectacular, especially on a clear day. Sometimes, you will literally be above the clouds. Some of the trails may have loose sections, please use caution.
