From here the main routes of the Collados del Asón Natural Park begin. This car park is usually full on weekends and you can also park on the other side of the road

This wonderful 700 meter long canyon is located in the heart of the Collados del Asón and is an incredible place. It will give you the feeling of smallness when walking among its immense limestone rock walls that were worn away by the glaciers that once occupied these territories.
