Dobrostanski biser cave

Overview

Dobrostan biser cave is a precipice cave in the Rhodopes, Chervenata stena Reserve. It is also known as Akhmet's Hole and the Cursed One. It is located 5 km from the village of Dobrostan and a 20-minute walk from Martsiganitsa hut.

Much of the cave is occupied mainly by stalagmites and stalactons (thick columns). Some have a greenish cover of algae and moss. There is an accumulation of large gravitational blocks in the center of the southwestern part of the hall. The depth of the entrance plumb is 15 meters. A small colony of bats also lives in the cave.

The cave was first explored in 1963 and was opened for tourist visits in 1990. Subsequently, however, it was closed and thieves stole the formed cave pearls and destroyed the cave ponds.

The cave is again ennobled and open to visitors in 2018, with visits on Friday, Saturday and Sunday.

Near the cave is the picturesque peak Popa - 1414 meters, to which there is also a path.
