Prohodna Cave is one of the most beautiful and easily accessible caves in Bulgaria. This is the longest natural cave tunnel in the country with length of 262 meters. What makes the cave unique is the natural holes on the ceiling resembling giant eyes which local people refer to them as the Eyes of God or the Eyes of Devil. The place is quite popular among climbers and bungee jumpers. It situated in northern Bulgaria close to Lukovit about one hour and a half drive away from Sofia.
How to get there:
From Sofia you should take the Hemus highway in the direction Varna, then to Lukovit and when you reach the village of Rumyantsevo you will find a sign to the village of Karlukovo on your left. Shortly after Karlukovo, there is a sign that shows the direction to the Prohodna cave.
If you continue about 100 meters after the sign that shows the direction to the Prohodna cave there is a road on your left. A bit further you will find a park space and the National Cave House "Peter Tranteev". There are several path which go from there. One of them we recommend leads to a pretty nice rock church - “St. Marina”. The path is steep but worthy. It take about 15 mins one way.
If you are up to more walking go back to the the main road where you turn left to the village of Karlukovo and continue in the direction of Lukovit for about 5 km. On your left you will see a big park space. Eco trail “Iskar-Panega” starts from there. Part of the first Geopark of the country, along the Panega river with good paths, wooden bridges and plenty of places to rest, this is a pleasant and easy trail to follow.
