BA-5

The entrance is elongated in shape, 3 by 2 m, and is located next to a tree. The pit begins with an entrance shaft, P21, which ends in a floor with numerous clasts. A new shaft, P8, leads to a chamber also covered with clasts. A small ramp and a small joint allow access to a new shaft, P9, which leads to a new chamber. A large chamber has large metric-sized blocks and a chimney in the ceiling.

The stream that is followed up to reach the entrance is normally dry. The main meander ends in a small shaft P6, which ends in a clay plug.

Continue along a meander that bifurcates. If you follow the left-hand meander, it ends in a small chamber, where an embedded slab makes continuation impossible. If you take the main meander, you descend to its base passing beneath shaft P9. After passing through a 7-metre gallery you reach a new meander that can be followed along its upper part or along its base, and by following it you reach a large chamber. The meander continues along the bottom of the chamber and ends in a small shaft P6.
