Kaliningrad Bay is 90 m long, up to 25 km wide and some 5 m deep. It is separated from the Baltic Sea by a narrow, 60 km long sandy spur, called the Mierzeja Wiślana. In the north, it is connected with the Gdansk Bay, the estuary of the Vistula River, by an 860m wide strait . The bay is the mouth of other rivers, too - the Pregola, the Paslek, the Elblag and the Nogat run into the Kaliningrad Bay as well. The main ports on the coast are Elblag , Baltiysk and Kaliningrad .
Due to the geomorphological uniqueness, the region is often visited by tourists. There are numerous holiday resorts along the coast, of which perhaps the best- known is Krynica Morska. The coast of the Kaliningrad Bay is recommendable for walking and cycling.
