Boninska Cave

2.5 km away from the village of Krushuna, in the outskirts of Devetashko Plateau, the Boninska Cave is situated. It differs from the rest of the caves in the same complex due to its great lengths and the fact that it’s a water cave. After a series of river siphons, we get to a large hall. A number of sinter formations can be seen around here. Underground waters are flowing through some of them. Calcite crystals on the ceiling have combined in weird frost-like shapes.
