Gay and lesbian couple use the enitre 3 Km of beach, particularly at the Weekends when some of the stunningly attractive locals strip down to their trunks and bikinins and go to the beach for the day.
Without being to literal, it pays to shop around, even if you are only window shopping.
Talk of official first then the more real unofficial reality that is Gran Canaria
The offical public Gay beach in Maspalomas is one of 9 designated sun bathing areas along the 3Km beach front that runs from Playa del Ingles beach to the end of the Maspalomas beach, ending at the Faro lighthouse.
The unofficial Gay area is 200 times larger than the "official area" and covers the entire Dunes section and extends into Playa del Ingles beach as far as the offical nudist section, so you have every excuse to get lost.
