Between the villages of Lecina and Alquézar, the River Vero has patiently carved its way through calcareous rock forming impressive rock walls peppered with hollows and caves. These are the result of water seeping through fractures in the ground and slowly dissolving the limestone.
The famous descents of the river Vero runs from Lecina to Alquézar. Several hiking trails can be practiced in the vicinity of this canyon:
- Camino del Rotizo
- Ruta de las Pasarelas del Vero
- Ruta al Tozal de Mallata
- Camino Natural del Somontano
