The Vaskivuori Nature Trail leads from the Usmi swimming beach to the old-growth forest landscapes of Hyvinkää. The total distance is about 4.5 kilometers: from the starting point, you walk about 1.4 kilometers to the 1.7-kilometer loop trail and return along the same connecting section. The trail takes you to the shore of Lake Mätälammi, a rocky ridge, and a stream valley. The nature trail is marked with yellow paint marks. Significant elevation changes and uneven terrain make it a challenging hike. The starting point is Usmi Beach at Usminjärventie 206. We recommend using the city’s hiking map to follow the route; the nature trail story maps are currently unavailable due to technical changes. The phone number and email address are the City of Hyvinkää’s general contact information.
