Jan,
Thanks for your rankings. Very useful information, and I am very impressed by all your travels. Coral Bay, Western Australia has been on my radar for quite a while and for you to rate it so highly is encouraging. I would llike to go there sometime. The only drawback I've seen, besides distance of travel and expense, is that uw photos sometimes show it can be a little murky with about 30 ft (10 m) visibility. That's acceptable to me but not great. As I have said several times on ScubaBoard (probably earlier in this very thread), I find it nearly impossible to rank snorkeling locations because there are advantages and disadvantages to them all. It would be nice if you could add some short information on why you liked (or disliked) all your locations, but I realize it would take quite a bit of time and effort to do this. Many times I have neglected to write trip reports about my snorkeling vacations because I know it takes some time to compose a good, well-written report.
