Lighthouse Reef is probably Belize's most well known atoll, due to the fact it houses Belize's most famous dive site, The Blue Hole. The Blue Hole is a cylindrical hole about 500 meters in diameter and 134M/440ft deep. Jacques Cousteau made this site famous in the 1960's he came with his research team and explored it. The dive will consist of a 130ft drop to view stalactites and stalagmites from what was once an above-ground cave system. It is a truly once in a lifetime experience. This dive is for the advanced diver only. There is also over 60 miles/100km of reef with drop offs starting as shallow as 30ft descending to well over 5000ft/1524m. You will have a very good chance to see sharks at Lighthouse Reef. We can choose any number of known and unknown sites to dive here, any of which will be spectacular.
