The dune trail is approximately 1.5 km long and allows you to appreciate various subsystems, from the embryonic dune areas on the edge of the beach, to the first corral where large trees appear.
This bicycle touring lane runs along one of the most outstanding landscapes of the Doñana Natural Park: the El Asperillo cliff, from which it takes its name.
Between the towns of Matalascañas and Mazagón and following the Cuesta Maneli path, is the Asperillo Cliff Natural Monument, a system of fossil dunes that extend along twelve hectares of coastline.
The boardwalk to the beach allows us to explore the Asperillo dune until reaching the cliff, declared a natural monument for its high geological and ecological value. At the foot of the beach, the cliff extends into the distance, crossed by streams of water that color it.
