"Tajos de Alhama" has been declared natural monument in 2011 and is only 26 ha big, but very impressive with its very steep canyon.
A hiking route is starting in town Alhama de Granada which is going into the canyon and leads you along the river. At the bottom of the canyon you have an impressive view on the town Alhama and you will see that they build it on a very steep clif. The route is ending at a small lake named "Presa del Rio Alhama".
