Another small funerary monument. Honestly, it wouldn't even be noticeable without the sign.

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.

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.
