Ruotsalon luonto- ja perinnepolku 6,4 km

Cars can be left in the parking area for Vähäjärvi lean-to shelter, which is located less than a hundred metres from Höökintie road, along which the trail leads. The nature trail is marked with blue paint, tapes, signposts and maps. The trail is mostly easy. There are sections of medium difficulty on either side of Hopeakallio and Maajärvi.

There is a landing site for paddlers at Vähäjärvi lean-to shelter. Vähäjärvi Lake in Kälviä is known for its freshwater pearl mussels, and you may come across mussel shells on its shores. The soil is calcareous, and limestone was extracted from a quarry located here in the 1950s. Calcareous soil produces unique vegetation. There is a herb-rich forest protection area where the rare Eggleaf twayblade can be found.
