Prohodna is 262 m long, very easy to walk through. There is a parking lot just next to the entrance. Then, you will need around 30 min to walk through it (with the photo stops).
The cave is a preferred place for bungee jumping and climbing. There are several sport climbing routes with different levels of difficulty.
Unlike other caves in Bulgaria, ‘The Eyes of God’ cave has no entrance fee and is always open for visits. During the weekends, there are more people enjoying the cave so you might want to stop by during a week day.
