The blue hole itself is boring. It's a 20-30min total dive time. Go to 130-140ft and then back up. I really enjoyed the 2 dives that followed it Half Moon Caye Wall and The Aquarium.
I thought it was ok. Interesting to see the structure down around 130-140' and we did see a few sharks about 90-100' but it's not a dive to see the critters that most of us like to see. If I go back to Belize I will do the dive again just for the opportunity to dive Half Moon and Aquarium .....that is unless I cough up enough to stay out near the Atolls and avoid Ambergris Caye altogether.
Anything wrong with ambergris caye in particular? Hoping to go later this year.
