An open ravine with multiple terraces and/or ledges, featuring four very attractive enclosed sections (tuff, travertine, early stages of flagstone formations, etc.), with pools that are neither deep nor pose any danger. No chaotic sections and the ground is very flat. Escape routes are available throughout the entire ravine. Some abseils can be climbed down.

We have to head to the charming village of Bergua, right in the heart of Sobrepuerto, which we’ll reach via a track – parts of which are tarmacked – that starts from Fiscal

We’ll cross the village towards the footbridges signposted ‘los Barrancos’ (PR117); we’ll reach the footbridges over the Forcos ravine, which we’ll cross, and then take the path that climbs up on the left-hand side of the valley, following the PR to Escartín. From the village of Escartín, head up towards the Serrato del Grijal (the upper part of the fields visible to the right of the village), where you’ll find a wall and some ancient ruins at a crossroads. We’ll take the path that descends – sometimes hidden by low scrub – cross a tributary (possible entry point) and continue until we reach the ravine bed. OPTION: Direct entry to the flooded section. If you wish to avoid the initial section of the ravine – which is open and of less interest – enter via a path that starts at a bend in the PR117 before reaching the village of Escartín. At a very sharp bend to the left, marked by an angled PR sign (with a cairn), a path branches off; it is easy to follow for about 20 metres to a viewpoint and then continues along the curve of the hillside without losing altitude. From the viewpoint, the path (unmarked) is quite overgrown in places. This track, gaining a little in altitude, leads us to a disused cobbled track. Following this, we’ll come to a landslide blocking the path, which we’ll bypass, then climb again to rejoin the track leading down to the riverbed, leaving us near the start of abseil 4.

At the end of abseil 14, we’ll see a clearly marked path on the left that leads us straight to the Forcos footbridges.
