Torrent del Cal Culestret + Torrent del Clot de l’Infern o Riu de Bonner

This route combines two canyons, Cal Culestret and Clot de l'Infern, in the Gòsol area. Cal Culestret is usually dry, while Clot de l'Infern typically has water due to its many tributaries. The approach varies from 1 minute to 1.5 hours, depending on the starting point, with options for one or two cars. The descent involves 6 to 10 rappels, with the longest being 25 meters. The route requires two 30-meter ropes and a full wetsuit. The equipment is rated as very good, featuring stainless steel parabolts and cordage to trees. The total descent time is around 3 hours, followed by a 35-minute return walk. Be mindful of potential high water levels in the Aigua del Vall river, which feeds into Clot de l'Infern.
