The "sunset dune" stands like a wall facing the ocean to the southwest of the village. From the top (30m), you can watch the slow descent of the sun towards the sea. As it sinks the sky takes on purplish tones and covers the sand with gold sequins. It is one of the park's mobile dunes: driven onto the beach by the winds on one side, and scooped out by the waves on the other, it is destined to disappear over time.
