Bulgaria Inside

A tall rock near the Bulgarian village of Karloukovo is one of the most interesting natural phenomena in the region. It is situated on the left bank of Iskur River, a kilometer away from the village and a little more than 110 km away from the capital of Sofia.

The rock looks as if someone has drilled a perfect circular hole in it. Some say that the rock resembles a clock tower that is missing its clock.

Several smaller rock towers surround the phenomenon. During the summer and winter solstices, sun rays pass through the circular hole. One theory claims that the rock was used as an ancient observatory.

Visitors can reach Provurtenika via several eco paths. A hut by the same name reveals panoramic view of the region and the rock phenomenon. You can reach Provurtenika both from the village of Karloukovo and the village of Reselets.

Provurtenika hut offers accommodation but have in mind that only basic services are available there.

Two kilometers away from the hut you will discover the National Caving House, which also offers accommodation. The town of Loukovit is situated approximately 11 km away and offers tourists the services of its several hotels.
