Located just to the north of the massís del Garraf, Castelldefels is a beautiful town famous for its long beach. Beside the beach, tourists are attracted by the Montjuic's 'Olympic Ring' one of the four major competition sites used for the 1992 Summer Olympics. The Olympic Stadium (Estadi Olimpic) now houses the Galeria Olimpica, a permanent exhibition and information centre about Barcelona's Olympics and its sports facilities. Also, the Palau Sant Jordi hosts a mixture of sporting events. The Picornell swimming-pools are currently open to the public.
