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

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.
