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.

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
