An information board at the Lilli nature house directs those interested to the study trail of the Lilli nature house. Taking an old lane, you reach a forest path which takes you to a sorb grove that the locals also know as the 'energy grove'. On the trail, you can admire rare lung lichen, rest on a stone covered in sorb roots and enjoy to the stillness of the forest. One branch of the trail will take you to Virapuu boulder that is shaped like a bun.
When taking the trail, make sure you go to the nature house first and ask for a bag with a map of the trail, a magnifier and a glossary of runes.
