It might is the most famous climbing crag in Bulgaria. About 120 km. away from Sofia, close to town of Lukovit. It is huge tunnel cave with about 40 m. height. Here you will find routes from 5c to 9a grade. Nice place to hide yourself from the heat in the summer, but it is quite oppressive. The half drive is on highway, that allows you in 1:30h. to reach the cave from Sofia. Pay attention, that after rain shower the rock becomes imbued and many of routes are wet, at least for few days, depends of intensity of the rain. But in the day of rain is very suitable for climbing, one of very few rain protected crags.
