It is a modest peak, but it is difficult to reach from the Izaskun neighbourhood. You have to be a little careful not to slip in the last few metres of the north face.

Mount Uzturre (733 m.), bounded by the basins of the Oria and Leitzaran rivers, is the quintessential Tolosa ascent. A cross erected in 1927 characterizes it, however the summit is a little higher, hidden by trees and without views, which is why the most popular objective for the mountaineer is found on this cross.

An emblematic summit for the people of Gipuzkoa, and a joy for everyone. In addition, going on the "highway", as they call it, is simple and easy to navigate.
