I didn't make it to Prohodna Cave...also for next time. We did go to Belogradchik...so close to Serbia too. I will make it to your beautiful country, I am sure of it.

Did you see this post of mine...more of the cave? You can actually see the whole thing in this one. https://steemit.com/travel/@samanthajbarnes/not-your-average-hole-in-the-wall-more-from-devetashka-cave-bulgaria
