Great gravel loop from Carcastillo if you start with the west side of the river, cross this bridge and return on the east side.

Just after leaving the parking lot, about 300 meters away, take the detour to the left and follow the path very easily and beautifully. If you have decent binoculars, you can see some chicks in the vulture colonies, depending on the time of year, and some adults all year round. Highly recommended, short and sweet.

It is a short but interesting walk. Going clockwise there is a possibility to swim shortly after the tunnel. The water is very cold

A very pleasant little village with a beautiful castle. A visit inside is highly recommended; they store your bikes in the courtyard :)
