We do this area from the train station in San Juan, then we pass through El Espartal and continue to Arnao. On the way back, we go up to the area of the northern path to return to the train station but via the wooden walkway between the dunes.

Just to the left of the large beach is the small, rougher bay, which can also be used for swimming in calm weather

The Philippe Cousteau Anchor Museum is an open-air monumental complex with free access located in the municipality of Castrillón, very close to Avilés on the Asturian coast. Up to 8 historical anchors recovered from the seabed and others donated are exhibited in this museum. The museum is dedicated to the memory of Jacques Cousteau's deceased son, Philippe Cousteau. Visiting it is an ideal plan to go with children, where they can enjoy the history of these enormous iron masses and the impressive views.
