Beautiful abseiling in a chasm in Saint Pé de Bigorre

This day of caving consists of going underground, not into a cave, but into a chasm. Large abseiling descents from the start to cross the Hayau shafts. This spider's thread route ends in the Bouhadère cave network, through which you emerge further down.

A second crossing is also possible at Saint Pé de Bigorre: the Moustalhous cave.
This route is more sporty and is therefore aimed at those who have already done the Hayau-Bouhadère crossing.
