Hi,
One gay night you can't miss is Pacha Scandal on sundays(@Pacha of Course)... The best night for gay people with La Troya@Amnesia on wednesday...
The Anfora is situated in the old Ibiza. If you're looking for pubs, you can go to the Dome in the center of Ibiza, or to the Soap Cafe next to it... There are also some pubs in the old Ibiza, like La Muralla...
Oh... and try the little restaurant where gay people use to go named Los Passarejos... it's tiny, but you'll eat perfect food, for nothing... (Always in Ibiza town, just ask for it, it's near Calla de le Virgen).
Don't know much of San An... Don't like it that much
About beaches, there is one well know of the gay people, is Es Cavalet, once there just ask for the beach named Chiringay... There is also Sa Trinxa (Salinas). But try to find some beautifull little beaches by your own... it's always worth it...
Cheers
Ibiza Rules!!!
