Col d'Aharza ou Ahartzako Lepoa (737m) walks

Oilarandoi is a magnificent viewpoint overlooking all the surrounding peaks. The nearby Munhoa and, further away, Iparla, Autza, Adarza and many others. At the summit, there was originally a hermitage, which was occupied from 1706 to 1792. The ruins were rebuilt twice, in 1941 and 1985. This hike includes sections with significant gradients of between 30 and 40%, but the reward is at the end and the view from the summit is well worth the effort.
