The big clubs are spread all over the Island,,,your best bet is staying in San an,, then catching busses or taxi to the big clubs,,, some places put on free busses to the clubs if you buy tickets from that bar...
Check out benniras beach,,, Sunday nights,, from 7 pm ish onwards,,, all kinds of hippy types turn up,, start playing bongo drums,, real fast,, it's like house music,, gets faster and faster,,, it's a great atmosphere down there,, folk swimming ,, dancing on the beach,, strange smells from all the weed,,ect,,,
The hippys sell drinks on the beach,, cheaper than the beach bars,
