I got my OW certification there in 1994, July, the typhoon season. I thought it was great diving then, but after diving much nicer places in the Philippines, SE Asia and Micronesia since then, I'd rate it about 6 out of 10. The island itself, though, is one of the nicest I've seen, and that's a draw to Boracay that will keep people coming back despite the mediocre diving. I think if Boracay were to get a few sanctuary dive areas like in Dumaguete or Anilao, you'd see remarkable changes to the reef and sealife within those areas in a matter of a few years. From what I remember in 1994, the coral was heavily damaged from all the small anchor hits from local fishermen (and dive boats), and there were very few large fish. The fish that I did see were very skittish b/c of exposure to fishing/spearfishing. That could have changed since then. I'll make it back there sometime, hopefully within the next year.
