• Busy on sunny days, since the small beaches by the old prison fill up fast in summer, so come early
• A rocky swimming spot at Långholmens klippbad, east of Västerbron on the same north shore, if the main beach is packed
• A path around the island for a walk after swimming, past the old prison buildings and the Mälarvarvet shipyard

Långholmsbadet is the public swimming beach on the north shore of Långholmen, a green island between Södermalm and Kungsholmen, right beside the Västerbron bridge and facing Riddarfjärden.

A path follows the shore around the whole island, past the old prison buildings. East of the bridge sits Långholmens klippbad, a rocky swimming spot first laid out as a bath for women and children.
