Looking like a giant eye in the ocean, the Great Blue Hole, about 50 miles off the coast of Belize, is a massive sink hole located in the Lighthouse Reef System. It’s 984 feet across and 394 feet deep. It’s considered one of the best scuba diving locations in the world. It was first a limestone cave system during the last ice age when the sea levels were lower. When the water rose, the roof collapsed and the cave system filled up to be the beautiful underwater kingdom it is today.
If I scuba-dived, it would definitely be on my bucket list.
