We ended up spending three nights there. The guards are really friendly and welcoming, and we felt completely safe (guard on duty 24/7).
We paid 35Q per night for camping, and 30Q per person for the entrance to the caves the first day.
The caves are really nice, nonetheless the light is not working anymore, so bring a lamp. We tried to do it without a guide, but doing so you miss all the specific rock formations. We were charged 20Q per person for a guide for the so-called extreme tour, in which you do a little of climbing at the end to see the underground water source.
