Park your bikes on Rue de la Plage or Rue de la Source, and walk down to admire the cliffs and the colours, especially at sunset.

Loscolo, a very beautiful sandy beach with a cycle path overlooking it. And perhaps a swim in the summer!

The dam itself is interesting, but the route is not ideal for cyclists.

After accessing the beach, there's a viewpoint with two benches to admire the landscape. Magical!

Those who know it will find a great resemblance to the beaches of Albufeira in Portugal.

A sweeping view through the river valley, nature at its finest, the grass swaying in the wind. Gravel paths that are easy to ride.
