Sopot's town beach runs about 4km along Gdańsk Bay and is 20m to 200m wide, depending on the sea level. A strip of dunes planted with willow, hawthorn and beach grass sits between the sand and the town, with 39 entrances leading down from the coastal park.

Swimming is allowed along the whole beach. Dogs and alcohol are not allowed on the sand.
