A bat's eye view! Fascinating drone footage reveals the inside of an eerie 70,000-year-old cave
Bats rule the roost when it comes to caves, ducking and diving through their dank dwellings.
And now new drone footage attempts to mimic a bat's point of view, taking viewers inside the eerie Devetashka cave in Bulgaria that was inhabited as far back as 70,000 years ago, but is now home to around 30,000 bats.
Footage captured by the YouTube channel SkyTrip reveals a giant cavern with large holes punctuating the length of it.
At one point, the camera steadily hovers along a dirt walkway with a smooth wall curving overhead.
