I took my daughter Toni for a look around Pierres on the evening.
We had a look at the entrance to the lower series, no problem for Toni but a bit tight for me.
I Only needed to give her a hand on the entrance pitch (up and down)
Pierres is a nice cave for the younger caving members giving them a chance to try out route finding and Lot's of crawling and climbing
All in all a good little trip
