The Ruta de Pedra trail is perhaps the second best trail in the Serra del Montsec mountains after the Congost de Mont-rebei, but it is a very interesting route.
A circular route of 11 km, starting and finishing at Càmping de la Vall d’Àger.
The first stop is at Pedra, at 1000 m above sea level.
A hermitage nestled into the southern face of Montsec d’Ares, visible from all across Vall d’Àger. Roman in style, it houses a statue of the Mare de Déu de Pedra, the patron saint of Vall d’Àger. In May 2016 Pedra was given a new roof, thanks to a micro-sponsorship campaign run by friends and residents of Àger.
The trail continues, passing through Cova d’en Rossell and the Gabrieló fountain.
On the route back towards the campsite, the last stop is in Colobor. Mare de Déu de Colobor was originally a Roman hermitage, later becoming an inn for pilgrims traveling to Noguera al Pallars in the sixteenth and seventeenth centuries.
Here is a map of the route
If you don’t want such a long trail or you are traveling with small children, you can walk as far as Pedra and then turn back. Only 4 km and with very interesting views.
You can also get to Pedra by car using a forest path.
