Dove the Blue Hole yesterday with Amigos Del Mar here in San Pedro on Ambergris Caye. The dive was spectacular! The boat moored to a bouy about 25 yards from the hole - we entered, tested our bouyancy (1st dive of the day) and swam to the hole. Descended to 45' and met on the sandy ledge - then ascended together into the hole. Our group was 12 divers, including three dive masters. The hole itself is very large - we could not see the other side during the dive - the water was a bit murky but viz was still about 50'. Descended to 130' and investigated the stalagtites and stalagmites left from this collapsed cave - really amazing! Bottom time was limited to eight minutes to avoid a decompression situation - but was plenty to see what we wanted to see. Above us during the entire dive were bull and reef shark - around 5-15 ft. in length - they were beautiful, and seemed as curious about us as we were about them - they never got closer than 40' to us. After our eight (8) minutes of bottom time elapsed we made a slow diagonal ascent along the wall, continuing to "take it all in." We hovered at 45' for about five minutes (a little extra safety margin) while watching the fish and sharks - During the 15' safety stop (for about 10 minutes - a bit extra for extra safety) the boat chummed the waters with fish (this is an OPTION - if everyone on the dive does not want to do this they won't chum) which attracted around 25 sharks of similar size to those mentioned above - they were SPECTACULAR - at NO time did anyone feel in danger - these were not JAWS sharks people :-) Everyone on the dive was PUMPED to have seen the beauty of the blue hole and the magnificent sea life... we boarded, motored to the Half Moon Caye area, and did a wall dive (SIT 1 hr) - then took a two (2) hour break on Half Moon Caye (saw the Boobie birds - neat!) and then did a dive at a sight called "The Aquarium" which had the nicest coral and fish yet... Overall an excellent experience! Will definately make the trip again on our next trip down to Belize.. The Blue Hole is a must-see.. it is an advanced dive due to it's depth, so you'll want a good number of dives under your belt before attempting (I have been waiting two years to make it - wanted some experience before making the dive) - the dive shop operated the trip in a safe and FUN manner (Amigos Del Mar) - their boat is AWESOME and the dive masters / captain were extremely friendly - the fruity rum drinks and snickers on the trip back to San Pedro didn't hurt either! :-) Gear was in very good shape and tanks all started above 3000 psi... Might need to make a stop at Wines DeVine (a MUST-VISIT while on the island) to pickup a bottle for the crew before leaving town- they earned it! :-)
