Trollegater is one of Sweden's largest known caves in primary rock. In the cave there is a system of passages nearly hundred metres long.

The cave is in the south of Östergötland where there are more primary rock caves than anywhere else in Scandinavia. Adventures and excitement await those who wish to explore Trollegater!

Trollegater is considered to have been formed immediately after the melting of the latest ice sheet in the south of Östergötland. At that time a number of earthquakes occurred to cause the appearance of cracks in the primary rock. When the ice retreated and exposed the land, tensions in the bedrock were released, which caused the cracks in the primary rock to become wider and deeper and the rocks were displaced. In this way a number of caves and deep crevices were formed in the surroundings.

The large cave, where according to old legends "the trolls" used to live, is the most interesting.

By means of a small passage you reach a chamber, in the far end of which you will find the entrances to two long passages that at the far end are connected. The height of the cave varies and in several places it is possible to stand upright. Tough clothing and a torch are recommended. There are also a number of smaller caves and hollows. Those who prefer to stay above ground can walk along the long and broad crevices - "gatera".

The reserve extends to 1,7 hectares and is owned by Kinda.
