I've been, took my kites, but got no wind! (Wasn't expecting too much .. had to go for a wedding out of season).
Some wicked spots, waves & flat water.
Great place - down to earth super relaxed people, with a simple way of life. Forget seatbelts & pollution control! .. diesel mini buses flog all around the island for $1 to go anywhere.
Can't remember the names of the places, but they're not hard to find... if you've got access to a Kiteboarder Mag from last year, they did an article on the joint.
Have fun!
p.s. Steve from Kitepower & Lachy (mrfloat) have a heap of experience there ..
