Långholmsbadet, Beach area in Långholmen Island, Sweden.

Långholmsbadet is a bathing site on Långholmen island with sandy beaches along Lake Mälaren. The area offers shallow swimming areas, green lawns, and natural rock formations for visitors to explore.

Långholmsbadet is a beach on the northern shore of Långholmen by Riddarfjärden, close to Västerbron. In 1998 it received the Blue Flag award for high water quality and safety, and was then the only bathing place in a European capital to hold it. Across Riddarfjärden lies Smedsuddsbadet; east of Västerbron on the same northern shore is Långholmens klippbad.

The beach faces Riddarfjärden, and directly across the water lies Smedsuddsbadet, so swimmers on both shores look at each other. East of Västerbron, on the same northern side of Långholmen, lies Långholmens klippbad, a rock bathing spot used alongside the sandy beach.

The site is equipped with changing facilities and showers for visitors. The Hornstull metro station on the red line provides direct access to reach the bathing area.
