The Rewa Spit, known locally as Szperk, is a narrow sandy spit approximately one kilometer long that extends into the Puck Bay, separating its warm, calm waters from the saltier, cooler waters of Gdańsk Bay. This natural formation was shaped by coastal currents, and its extension continues underwater as a sandbank called Rewa Mew, stretching toward the Hel Peninsula. During low tides, the sandy spit extends even further, and small islands and shoals emerge on the water’s surface – a result of fluctuating water levels in the bay. The spit is a popular spot for water sports enthusiasts, including windsurfing and kitesurfing, thanks to the wind protection its unique location provides. Diving enthusiasts can also explore three shipwrecks here, adding an exciting element to the underwater landscape. One of the unique events held in Rewa is the "Herring March" – an annual journey in which adventurers wade across the spit, heading toward Kuźnica on Hel Peninsula. The route, about 12 kilometers long, partially requires swimming through a deeper channel known as Głębinka. Located in the beautiful setting of Puck Bay, the Rewa Spit is not only a scenic attraction but also one of the most interesting natural and cultural sites in Kashubia.
