Trollegater Nature Reserve is one of Swedens largest bedrock caves. If you feel brave enough you can crawl in and walk through an almost 100 meter long cave system. Just a short drive from the city Linköping where I grew up, you drive on winding roads leading to a lush forest with natural wonders. With its mystique vibe and things like barbecue area and dry toilet, this is a popular spot for families and school outings.

Take a walk around in this story book-looking place, just watch out for Trolls! Here you also find parts of the Östgötaleden trail going through the reserve.
