San Adrián Tunnel

Highlight • Cave

Curious formation that allows us to go from one side of the mountain to the other.
Be careful if it is wet or damp as the stones slip a lot.

Aizkorri Summit (1,523 m)

Highlight • Summit

An essential for those of us who live around here, without wind (which rarely happens around there) it must be a joy to sit quietly to have a sandwich. Well, actually, in the hermitage there is a small bench that looks towards the Guipuzcoan side where the wind does not usually blow. Too bad he's always busy.

Eye of Aitzulo

Highlight • Cave

If you climb from Araotz, follow the PR, and the climb is very easy and short.
From the cave parking lot, it's much steeper and zigzags. About 2.5 or 3 km with a lot of elevation gain.

In times of rain, the road is a real mud, but for example now in spring, you can go up a path that runs parallel to the river, you cross the river through a lock that has no major complication

One of the emblems of the Sierra, although it is not the highest, it is 1548m, the Aizkorri 1523m. A delight in any case.

What's the deal with the names? Are "aketegi" and "aitxuri" the same thing?

Achievement of several waterfalls hidden among a beech forest. Although they show their maximum splendor after a rainy episode, the path turns into a muddy area which makes it quite uncomfortable to run.
