Ar_xxx, Aven

At the moment, the aven A. is possibly the world reference for helictites clusters. For this reason, the cave must be protected very strictly and we can give no information. The glassy calcite crystals are too fragile and other caves in the area have suffered dramatically in the past - due to an unsufficient protection. Nevertheless a visit of the aven A. is an amazing experience. Just lying on the ground and watching the million of helicitites atop. One can even hear the growing of the crystals!
Conclusion: One of the most beautiful caves we ever visited.
