Cave is a bit difficult to see from the path. A bit of climbing is required to see into the cave. The best way to get up is to the left of the sign in the large arc.

Nice passage through a rock face, with a nice view towards Vienna's local mountains. Some easy climbing is required to get there.

It's better to go during the colder season if you want to see bats.
