The Aitzondo waterfall is located in the Aiako Harria natural park, at the western end of the Pyrenees. This waterfall is one of the largest in Guipuzcoa, with a drop of 140 meters that ends in a small pond.

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.

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.

On the coastal path of the route to the cliffs of Mount Ulia in San Sebastian we come across the Peña de Ataloi, this strange and beautiful rock formation in the shape of a cave that melts in your hands.

This wonder of nature is one of the numerous geoforms that you can find in the Valley of Colors. To get there you will have to deviate a little from the trail, but it is worth it.

Forest trail along the Karrika River. The trail passes through a small tunnel near Bidaita. The forested landscape is the perfect setting for any good hike.

You can't get here because the route no longer exists (slipped). Just follow the trail marker instead of komoot. At the end there is a great river where you can refresh yourself in the summer

Small cavity with inlet and outlet, although not practicable. Just below the rock in front of the top / hermitage / castle.

Access to the interior is easy, but I can't say the same about the path leading up to here.
