Svanvik is an open and shallow bay, where great amounts of seabirds and wading birds gather during migration. The bay is particularly popular among swans and here you can encounter three different species of them. A short trail leads to a bird tower by the beach. The trail goes through a grove – a natural pasture for cattle. Dogs are not allowed in the area for this reason. The trail starts by Tvärminnentie, about 11 km from the town center.
