The trail runs through Tourujoki nature reserve. The river valley has very exceptional vegetation compared to any other places in the city. This verdant broad leaf woodland is located right next to the center of Jyväskylä, offering recreation for busy hikers as well. There are information boards along the path, introducing the plants of broad leaf woodland, water protection and cultural history of the area.
