A Once you've done it, many experienced divers relegate it to a "logbook dive" or "ticket punch" experience.
I used to feel that way, since the first few times I dove it was from a boat from San Pedro. As mentioned, it was a long ride out and frankly, if it wasn't for the great diving out at Halfmoon Caye next door, I probably would have clocked it up as a "been there, done that" dive. The depth of the dive there, was no biggie, since it's pretty typical of the depths we dive at home, but I was never thrilled at being surrounded by several boats full of people I didn't know, most of whom were WAY past their comfort zone and and ALL of us were under-equipped with no one having redundancy of any sort. Honestly, the only thing surprising about the number of "incidences" out there is that there aren't more of them. As a photographer, it was very difficult to get a decent shot due to the random limbs in my way.
Having said this, the past couple of years, we have stayed out at Long Caye at Huracan Diving. The BH is about a 15 minute ride away so we are finished our dives there before anyone else has even arrived. Last year, we ( "We" being me, my wife, a friend and our guide perhaps) had a number of fantastic dives. There was no one else there at all, so we had great vis, the sharks hadn't been spooked and we dove areas not normally visited.
I'm looking forward to our return next month. I've decided to add a stage bottle to my kit this year although all of us are gas-misers so it's unlikely to be needed...
As others have mentioned, if you are a novice diver, I'd give it a pass, however, I'd still take the trip because I think the diving in that area is the best in Belize.
