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.

Very beautiful cave. Was converted into a church 1000 years ago. Worth seeing.

Entering is expressly forbidden by a sign, but if you do it anyway, you should be aware that there are many rock falls

The Martha cave is the second largest gypsum karst cave in the Hainholz gypsum karst landscape nature reserve, after the Jetten cave. It was created by the collapse of a large underground cavity in the karst rock. Access is at the steep edge of a temporarily filled sinkhole.
