#12 – The Great Blue Hole – Belize
Every diver in the world must visit the Great Blue Hole, an enormous submarine sinkhole whose whereabouts is off the coast of Belize. If you are a diver, you can’t call yourself a professional and experienced diver if you haven’t taken a dive into this 354 feet (or 108 meters) deep submarine sinkhole.
You can find Great Blue Hole 70 kilometers from Belize City. This natural phenomenon is surrounded by a small atoll called Lighthouse Reef.
