Algorri Flysch

Highlight • Natural Monument

Depending on the tide, the section at sea level is either accessible, not accessible, or only accessible to a limited extent. But in any case, it's extremely worthwhile.

ATTENTION/WARNING: The first or - if you are doing a reversed tour - the last part of the coast is only recommended/possible at absolute low tide. Otherwise it is very dangerous and difficult and definitely not possible with children.

The first (or last section if reversing the route) section is absolutely NOT accessible. Possibly only at extreme low tide. We were there an hour before extreme low tide, and it was completely impossible. I would choose to simply follow the route at a higher elevation and skip the "beach" section. Especially since the beach is made up of large stones and rocks, difficult to walk on because you always have to watch your step due to loose stones.

Mostly the area is windy especially due to topography. Do not forget to carry water with yourself. Enjoy the Bay of Biscay

Enjoy this 8.9-kilometer route near Deba, Gipuzkoa. The route is generally classified as difficult and can usually be completed in 3 hours 17 minutes. Although the route is ideal for trekking and hiking and is often busy, you can enjoy a bit of peace here at the right time of day. This linear route is recommended for experienced hikers who want to enjoy beautiful views in the protected biotope of the Deba-Zumaia coastal section/arteko itsasertzeko Babestutako Biotopoa. The hike starts in Elorriaga and goes along the "GR®121 Gipuzkoa Tour"/"GR®121 Gipuzkoako bira" to Deva, passing by Sakoneta, the Mendata waterfall, Arranomendi, the hermitage of Santa Katalina and the Santiago de Deba beach

Very beautiful hike along the ocean at the foot of the cliffs. But be careful: you must check the tide times to avoid getting stuck. On the other hand, the hike is quite difficult because of the pebbles, stones and flish to cross. It is essential to have suitable shoes and good physical condition.
