Outside of Großau, between Überland and Waldhaus, there are 2 ice cellars hidden in the forest, which are the subject of numerous stories. One tells of 5 defensive towers that are said to have once existed here. A brick vault is said to have been built on top of the rest of the 2 towers. In any case, the two covered shafts were used as ice cellars by the local butchers/inns. In order to extract the ice blocks, "ice rights" were granted on the ponds. There is no path to this well-preserved cellar; you have to climb over the stream and up the steep slope to get to the entrance. Be careful, access to the deep shaft of the ice cellar is not secured, danger of falling!

If you start from Raabs, you will be greeted at the beginning of the path along the Moravian Thaya by an impressive rock that towers over the path like a large roof. There is a figure of the Virgin Mary in a grotto.

It is worth driving a little (100 meters) along the Moravian Dyje along the hiking trail to the rocky outcrop. An idyllic place on the beautiful shore hiking trail

Not only the interesting underground passage should be planned to stay. The associated inn also has an absolute recommendation. Good kitchen and friendly staff.

This really idyllic place is a bit off the bike path, under a large rocky outcrop, directly on the Deutsche Thaya. The place is called "Unteres Hackelstein Felsdach". Up to this point you can easily cycle there. Just be careful with your head 😉. Then a single trail begins.

The rock roof can be seen clearly in the gigantic boulder from the opposite bank. You have to climb up a few rubbed stones to get to the spot.
