Illern is right in the centre of the nature reserve. It's waters are crystal clear, and the biodiversity is rich - a popular spot for fishers, birdwatchers and nature lovers …
The Trollstenen are easy to reach on foot or, if you're more experienced, by mountain bike. The huge rock resting on three stones is worth the detour. There's also a nice story about it on the signs (even in German)❤️.
