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.

Sand Caves in Heers

Highlight • Cave

Right next to the caves soft white sand, rather not suitable for walking.
But definitely along the paths.

With blue skies and temperatures around 0 degrees with traces of fog, a little ground frost in the shade and rays of sunlight falling across the landscape, you get great color combinations and moods.

The combination of sandstone caves and castle and the mill at the end is a great trio - equally exciting for dogs and humans ;-)

The sandstone caves and the route suggested by komoot are really worth a trip. Very impressive!!!

The times are not correct at all, a few satellites were missing in between. Including a bratwurst break, we were on the road for a good 3 hours.

The third part of the day starts again very touristy with the castle ruins and Regenstein Fortress. But the visit is definitely worth it, as is the 4 euro entrance fee. Very interesting what was there in and on the rock.
After the castle we walked to the Regenstein mill, or rather its impressive one
Remnants. Now the Great Papenberg …

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.
