GSA has different sections for water polo, swimming and recently added a diving section. On Monday nights and Sunday afternoons, training is held in the Marnix; on other days they are held in the Sloterpark Baths.
All three sections are open to beginners as well advanced swimmers. An extra trainer is available on Mondays for beginners in the swimming section. Interested parties are allowed two free trial sessions.
The GSA water polo-team won first prize at the Eurogames in Barcelona and their swimming club came second as the best gay swimming club at the club championship in Eindhoven. As well as being active participants at many international tournaments, GSA has a flourishing society life with get-togethers for a drink, an annual party and participation in the Canal Parade.
