It begins inside the Puszcza Darżlubska Wilderness, located in the northernmost part of the geographical region of Pobrzeże Kaszubskie. Darżlubie Forest contains two nature reserves. On the south–side it borders the Tricity Landscape Park from which, it is separated by the Reda river. The wilderness, is also the source of river Gizdepka.

The Piaśnica wilderness, where the river begins, is a place of Polish and Jewish martyrology; the second largest site of mass killings of Polish civilians in Pomerania during World War II. The Mass murders in Piaśnica, of about 12,000–16,000 hostages, were committed by the Nazis between the fall of 1939 and spring of 1940 near the town of Wielka Piaśnica.
