A very popular excursion destination. The very beautiful and large crystal cave can be visited with guided tours. Cave concerts are also held here regularly. They are impressive due to the special acoustics. Dates can be found at the Friedrichroda tourist information office.

The oven holes resemble historical stone ovens. Their origin is unclear, but two possible theories exist: They could be former lava tunnels, or they were formed by water erosion. And of course these geological beauties made it into the world of legends. Namely with the legend of a mountain giant.

The Torstein is an absolute must see on a hike in Lauchagrund. Surefootedness and sturdy shoes are recommended. The Torsten is a 6m high rock gate. This is located near a Celtic hill fort ruin. Strategically cleverly located and probably also with religious significance, the area around the Torstein leads back to early history.

The burnt out stone at Oberhof is an artificial breakthrough through the rock. It was important for the Lütsche Flößgraben when it was built. The alternation of fire and ice-cold water made the stone brittle and could be worked with mining tools. A 38 m long, 2.3 m high and 2.2 m wide tunnel was created. If you follow the path further you come to the “Hohen Stein” with a wonderful view. The path back to Oberhof leads past the upper Sieglitzteich.
