Helicopter cave

The cave entrance is situated in a lake at the bottom of a karst sinkhole in Russia. A guesthouse is conveniently located nearby, offering services to fill or rent gas cylinders for diving purposes.

During the investigation of the cave, no underwater inhabitants were discovered in the examined section. However, it should be noted that snakes can be encountered in the lake and at the sinkhole's bottom during the summer season.

The lake provides access to two tunnels: one on the right and another on the left. The left passage descends at a 45-degree slope, reaching a depth of 43 meters. It leads to a room with narrow passages on either side. On the other hand, the right path descends gradually to a depth of 37 meters before abruptly breaking down. These passages are interconnected at a depth of 10-20 meters, forming an arch. The visibility within the cave is typically around 3-5 meters during the winter season.

Important information for divers interested in exploring this site includes a maximum explored depth of 54 meters (in the right passage), a visibility of 6 meters, and a recommended diver level of expert.
