I mentioned a Serbian cave with bats recently. Well, compared to that cave near Sagano in the Philippines, there weren't any there at all. And honestly, all the caves in Serbia are so well-developed and lit up—you can visit them without any hassle.

Sumagintskaya Cave is nothing like that. You can only enter with a guide (same goes for all the other nearby attractions), there's no lighting inside—just your own flashlights—and there's a lot of water, so halfway through the route we had to take off our shoes and continue barefoot. In a couple of spots, you can only climb up using a rope. No other way around it.

It's really beautiful though. The wilderness and lack of artificial light give it its own charm. I was seriously impressed.
