The Vallonjärvi nature trail in Valkeakoski is only 2.2 km long. The nature trail, which starts from the gravel storage area along the connecting road, goes around the eastern and northern shores of Lake Vallonjärvi.
At the Lake Vallonjärvi you can find many different bird species nesting like Common Pochard, Eurasian Wigeon and Common Snipe. The extensive shorelines and ravines of the lake are important predatory areas for many birds of prey. These, and especially waterfowl, are easiest to observe from a bird tower along the nature trail.
