Långholmen

Långholmen is a wooded island park in central Stockholm. Its western tip, a short walk from Hornstull metro station, has long been known as an outdoor cruising area. It's a public park, also used by walkers, swimmers and families, so be discreet. Older listings describe it as 'once very popular', and apps have reduced activity at most outdoor spots. Expect little outside summer afternoons and evenings. Go with low expectations, tell someone where you are after dark, and leave nothing behind.
