Small Sandstone Caves in the Harz

Highlight • Cave

The small sandstone caves are no less spectacular than their large counterparts. My dogs never wanted to stop playing between the dark caves.

We had three children (6 and 7 years old) with us. Great family tour, not suitable for strollers.
Lots of highlights for the kids.

We were in the Harz Mountains with the seminar group. I was very surprised about the interesting sandstone area there. I have to go there again.

A weekend like this always goes by far too quickly. Our girls' get-together concluded with a walk around Regenstein. We then had a delicious trout for lunch at Michaelstein Monastery.
