The one-way Tihu study trail leads to the largest lake in Hiiumaa, located in a hollow between dunes. There are information boards by the trail describing the paludification process. At the end of the trail, a 200 m boardwalk leads to an observation deck at Lake Tihu. While resting at the observation deck you can watch the interesting water and wetland birds, enjoy the silence or the voices of the surrounding nature. In summer you can admire water-lilies and in autumn you can pick berries and mushrooms growing by the trail.

There is a cosy forest hut by the trail where you can stay, if you wish to enjoy nature longer.
