Pobiti Kamani is a natural phenomenon some 20 kilometers west of Varna – perfect for a day trip if you are staying in Varna. It’s Bulgaria’s only desert, and it’s made up of sand dunes and rock formations as well as being home to variety of flora and fauna. There are many theories about the origin of these stone columns that reach up to 7 meters high, but none of them have been proven. These columns are hollow and they look as if they are stuck in the sand. The best way to reach the Stone Desert is by car, there’s a parking area nearby.
