Beach19 is one of the most beautiful (gay)beaches in Portugal. Located just under Lisbon it's an ideal place to spend your gay holiday.
The first part of the beach still is for nudisme, used by gay people as well as hetero sunbathers. If you walk south along the beach about 200 meters further from the entrance you'll find the gay beach. It stretches about 500 meters,
There used to be a beach train from Costa de Caparica, but 2012 is the last year it will be in service, only on weekends.
Best is to rent a car and drive there directly.
