The village of Sulino is located on the route of the 7th section of the wildlife corridor established on the Pęzinka, which is a tributary of the Ina. The main objective of the project is to create a wildlife corridor by opening the main channel of the Ina river and its major tributaries (Krąpiel, Krępa, Pęzinka, Wiśniówka, Małka, Reczyca, Mała Ina, Stobnica and Wardynka) to diadromous fish. This will allow the fish species which spend most of their life in marine waters, to reach spawning grounds in fresh water. The bridge over the Pęzinka offers a nice view on the river and the nearby meadows.
