Tips from the Community

September 14, 2025, Gazume Summit

A peak very close to Hernio. It's highly recommended to visit it after reaching the summit of Hernio, as the descent from this point to the Iturrihotz hamlet is much more manageable.

Point before reaching the summit of Ernio. The pilgrimage takes place on Sundays in September. At this point, the hermit who sells cowbells and ribbons stands.

Being already in the Hernio, why not lengthen the path a little more and reach another super cool peak? the only penalty is the antenna booth.

In Basque, "erniozaleak", the most appropriate name, just a few meters before reaching the crosses of the summit.

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.

Coming from Hernio, it seems to me the best place to pay a little tribute. It reminds me of the inn in the fields of Urbía.

Little more than a gentle uphill slope, if you come from Gazume. Worth.
