Avenc dels Bolets

An entrance of reduced dimensions gives way to a 15-metre pit that widens as one descends, with a ledge found at 8 metres.

The pit ends in a long ramp full of debris. To continue, one must follow the ramp seeking the maximum slope until reaching a small chamber where we find two 10-metre pits that converge halfway down the descent; it is preferable to descend by the one at the back of the chamber, which has a rock bridge that we will use for rigging. From here the development of the cavity changes in the opposite direction to the initial route, forming an almost rectilinear gallery, narrow and with a very high ceiling for some 30 metres, until reaching a chaos of blocks wedged in the wall. Above them one reaches an elongated chamber with a low ceiling. Below the blocks and overcoming some narrow passages, one arrives at a new chamber with a low ceiling and slightly inclined; at its back, a small step leads to the point of maximum depth at -47.2 metres.

Although this descent can be done by downclimbing, it is advisable to rig a rope that we can tie to a pine tree found near the entrance.
