This is a dry descent (if there’s water running, be careful as it’s very narrow – and don’t attempt the Riu Fred and Ribera Salada route, as it’s suicidal) and very narrow throughout the first section, except for the final stretch, which is wider but dark and heavily eroded. On emerging, you can head up to the right via a footbridge over the Riu Fred and walk back to Mas Roquer (30')

From Sant Llorenç de Morunys, heading towards Solsona via the Coll del Jou, take the LV-4241-b road. Después del hostal Cap del Pla cogeremos una carretera que sale dirección Montpol- Pont del Clop. Unos metros después la carretera se bifurca y cogeremos el cruce a la izquierda y el siguiente cruce a la derecha. Esta carretera nos lleva al Pont del Clop, donde dejaremos el vehículo de salida. Continuaremos por la misma carretera hasta encontrar la ermita de Montpol. Aquí aparcaremos el vehículo de entrada.

Opposite the car park and a few metres further down, a track leads uphill which, after 500 metres, will take us to the abandoned farmhouse, Mas Requer. The ravine is just behind Mas Requer. We’ll continue along the track, which will take us to the ravine after a few metres. We’ll head down through the woods to reach

The first 300 metres follow the riverbed, which is heavily overgrown but can be bypassed on the left until it begins to narrow into a gorge. After that, the ravine forms and the route begins with some dark ledges and narrow passages.

We set off from Pont del Clop, where our second car is waiting

All year round, except during floods. The water flow must be very low. This canyon is usually dry.
