Here is the original "Blue Grotto" entrance to the Unicorn Cave. Unfortunately completely fenced in and therefore very poorly visible. Too bad, this corner could be made a little more attractive/interesting (and still left fenced off)

I can still recommend the tour of the unicorn cave to everyone! Very interesting

The Blue Grotto is located at the end of the Unicorn Cave. There's also a back entrance there, which isn't used. From the outside, all that's visible is a large hole, secured by a high fence. This also prevents animals from falling from the forest into the cave.
