Janet,
Bonaire will certainly and far exceed your expections for snorkeling, the areas which is almost the entire north, west and south sides of the island are shore accessible snorkeling opportunities. There are drift snorkeling opportunities as well. Kayaking, while I haven't personally done it should be good. Now the negative based on your criteria, while biking is certainly easy its a flat dry island, hiking/walking of course can do but again nothing really to see, you won't find the dramatic vista like on St. Lucia for example. The beaches are not great, they are generally grainy small ground coral bits, where water shoes are a necessity. The island is quiet as far as tourism goes but note there is some crime problems, mostly just theft. Bottomline, if you are going for diving and/or snorkeling its top notch...for everything else its mediocre, and definitely laid back.

Hi Janet, I think Bonaire would be a great choice for you. The snorkeling is outstanding, and if you know where to go the hiking is great too. We hiked to the top of Subi Brandaris (the island high point)located in Washington-Slagbaii National Park and the views were awesome. Obviously the arid island would not compare to St Lucia, but it still has some great topside attractions. Check out our travel journal for a trip report and tons of photos..maybe it will help you make up your mind. Our website is www.nbhtravel.com Hope this info helps you out. Have a great trip wherever you choose. Oh yeah, we stayed at the Divi Flamingo and really liked it...great snorkeling right in front of the hotel and the Chibi Chibi is a great place to eat. Let me know if you have any questions.

Definitely take aqua socks or something to wear on your walk from shore to a couple of feet of water. from their the snorkling is greatly varied. The Andrea 1 site was our favorite. The coral is good and so are the fish. Our web site dave-lori-home.com has some eating tips and has plenty of pictures. The desert country side is actually pretty.
