Huge tunnel cave with tufas and pockets and two huge holes in the roof which look like eyes


In rural Bulgaria is this massive cave one could fly a helicopter through. Has 'The eyes of god' feature in the roof and also great climbing but mostly moderate to hard routes.

Access issues

Put Karlukovo in your GPS navigation system and drive. If you have the Bulgarian Climbing Guidebook then there is a description of how to get there in that.

Where to stay

Camping at the entrance to the cave on the rolling green hills. There are a couple of shepards who move their animals through the area. They are nice and it is normal to offer them a gift or some Rakija (alcoholic spirits) and they will often give you some of their homemade cheese or milk.
