Adarra

Adarra is a mountain summit in San Sebastian that rises 811 meters between the Urumea and Leitzaran valleys, displaying slate outcrops and sandstone formations from the Paleozoic period. The rock structures reflect the geological history of the region.

The mountain contains remnants of prehistoric human activity, with 34 stone circles, four dolmens, three cists, and two menhirs that date from the Neolithic and Bronze Age periods. These archaeological features indicate the site has held significance for thousands of years.

The summit serves as a gathering place for local people, especially on New Year's Day when residents come together to welcome the first sunrise with music and celebration. This tradition shows how the mountain holds a special role in the community's yearly rhythm.

The main access starts at Besabi in Urnieta, where you can park your vehicle and follow clearly marked trails through the forest. The route is straightforward and suitable for most walkers.

The eastern slopes preserve patches of native forest with indigenous tree species, while the western side features pine plantations and grasslands used for livestock grazing. This contrast reveals how the mountain serves different purposes across its different sides.
