Beach 19 is a very large gay nude beach which is part of a Nature Reserve and it’s about 30km south of Lisbon’s center. The name comes from the fact that the zone around the stop number 19 of the beach train became the area most popular with gays. Beach 19 is the “gay-section” of a very extensive stretch of sand known as Costa da Caparica. It is officially a nude beach (by law) but you can opt between being naked or keeping your swim-suit.
