The routes are not marked. Very poor safety. Malkata Vratza-50m high. Good opportunities for top rope climbing. Although generally stable the rock is fragile on some routes especially on easier ones.
Summer is very hot.
Plenty of snakes. Danger of falling stones on the higher walls especially in conditions of high temperature amplitudes and heavy rains. In summer climbers on certain walls may be contaminated by a local disease expressed in intense inflammations of the skin. It's something like after flea bites. After 1 or 2 weeks it's over.
