Trollegater, Nature reserve with cave system in Kinda Municipality, Sweden

Trollegater is a nature reserve featuring an underground cave network running through bedrock in Kinda Municipality in southern Sweden. The passages and chambers were carved by natural processes and offer visitors the chance to walk through different sections of the network.

The caves formed at the end of the last ice age, about 10,000 years ago, when the land rose after the ice melted and released tensions in the granite, widening and deepening existing cracks. The reserve was declared in 1980. Two adventurers first entered the caves in 1964.

The name means "the trolls' streets" in Swedish, and folklore held that trolls lived in the largest cave. The reddish colour of the rock was said to come from the trolls' butchering inside the caves, though it is actually a lichen of that shade. Locals long knew the caves but did not enter them until two adventurers did so in 1964.

The reserve lies 8 km west of Rimforsa in Kinda Municipality, with the Östgötaleden trail passing by. Facilities include a barbecue hut, information boards, a toilet and marked walking paths. The cave entrances and some passages inside are narrow, so bring a torch and wear clothes you do not mind getting dirty.

The reddish colour on the cave walls is often attributed to trolls' butchering, but it is actually a lichen of that tone. Locals long knew the caves yet avoided them; two adventurers first went inside in 1964.
