For diving Bonaire is probably as good as you'll ever find anywhere.
Good Snorkeling can be found almost anywhere along the road right from the shore.
Bonaire has some large salt flats and Flamingos in the hilly area where at the base are more salt flats there are also brightly colored lizards running around. You could say its like one of the Galapago islands in the Caribbean.
Captain Dons Habitat and the Divi Flamingo are two good places for lodging and dive trips. The food at the Divi is 1 star but there are plenty of restaurants nearby. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Cheers.gif" alt="" />
