Krynica Morska is located on the relatively shallow Bay of Gdansk, so the Baltic waters in the area are warmer. In addition, its location on a sandy spit makes the beach in Krynica Morska very wide with yellow fine sand. The bathing area, which is guarded in summer, is as wide as 500 metres - the section from the height of the Neptun resort to the exit from Marynarzy Street.
Apart from the guarded bathing area, Krynica also has no shortage of beaches with a wild character. It should be remembered that the centre of Krynica and its eastern part - Piaski - are separated by a distance of more than 10 kilometres, and a sandy shore stretches along this entire stretch. There is also a naturist beach near Piaski (Nowa Karczma).
