3,7 kilometers long nature trail goes trough the Tremanskärr nature reserve.
The route of the nature trail is an excellent introduction to the nature of northern Espoo and the Tremanskärr domed bog. The trail is 3.7 km long and has 13 information boards. There are also two shorter alternative trails, one running around Tremanskärr (2.8 km) and the other running through Kurkijärvi (3.4 km).
Access to the trail is from the car park facing the Pohjois-Espoo and Kalajärvi school on Vihdintie. The nature trail does not require heavy hiking equipment. Duckboards have been laid over the most difficult parts.
