Forat de les Olles

The best-known old part of the cavity begins with a short gallery that brings us to an extremely narrow passage, behind which the first drop of about 3 metres of elevation change opens up. From this point, the profile of the cavity extends towards the N, and we must descend a fairly irregular pit with some ledges until reaching -32 metres of depth. At this point a gallery begins with a steep slope and in a direction completely opposite to the one we had been following; at the end of the slope we find a 9-metre pit and at its base a small drop that places us at the maximum elevation change of the cavity of -52 metres.

The new route begins just past the entrance, where we find on the other side of the pit and in a N direction a ascending meander that brings us up to the +8 metre level, continuing along a downward-sloping ramp covered with very slippery white mud. Next we find the pou de la Il·lusió (-20 m) of about 3 to 4 metres in diameter that leads us to a fissure, which leads to a small chamber. The direction changes towards the W, as does the morphology of the cavity; after the chamber we find a small step where a meandering gallery begins, de les Xemeneies. We will encounter in this gallery various chimneys, the floor covered with blocks and some sections with water. The ceiling of the gallery gradually lowers and we have to crawl for about 14 metres until reaching the dels Rat-penats chamber where this new section of the cavity ends, which reaches the same depth as the previously known one. The total elevation change of the cavity is 60 metres (+8/-52), and the route is 268 metres.

At the base of the small chamber there is an impassable water drainage point, where in rainy periods the water plunges in a cascade coming from the infiltrations it receives from the galleries described below. At the beginning of the de les Xemeneies gallery we find another small waterfall.

The downward-sloping ramp is covered with very slippery white mud where a safety rope must be installed.
