The cave lies 2 kilometres (1.2 mi) from Karlukovo, near the Karlukovo–Lukovit road. It is also accessible from Rumyantsevo, and there is a parking lot near the Small Entrance. Near Prohodna is the much longer cave Temnata Dupka, and a pathway from the Big Entrance of Prohodna leads to the Petar Tranteev National Caving House, one of the 100 Tourist Sites of Bulgaria.[1]
