Oandu plant trail is like a natural botanical garden. You will be surprised to find out how many different plants can be found on a 1 km area! In the autumn, it is like an open-air mushroom exhibition there (up to 60 species of mushrooms can be seen there in some years).

However, if you are not interested in mushrooms, it is still lovely and safe to go for a walk there. There is an ice cellar and beds with flowers, vegetables, and herbs from the manor era. In addition to signposts introducing the local plant communities and plants, there are five information boards on the shores of Oandu artificial lake, which introduce the animals living in Lahemaa.
