The second dive I had on Grand cayman, (north wall) we saw a hammerhead. I sat back and watched. It was pretty cool. when we surfaced, the dive guide was going hystarical about what he saw. It was then that I realized that maybe it was a pretty significant sighting. Anyway, that's my favorite place to dive and between the turtles. stink ray, eagle ray, and other cool wildlife. you won't be disappointed....... I'm going agian in April.
