"And here we go – down into the deep blue sea, at the Great Blue Hole, a UNESCO World Heritage Site and one of the most remarkable underwater kingdoms the world has to offer. I didn't get a change to visit the stalagmites and stalactites deep down in the hole – I'm not quite ready to go that deep as a diver – but I was able to explore much of what the hole has to offer. Even burgeoning divers like me can get down with their crew and explore a world they never knew existed. GoPro Hero3+ Silver | Aperture f/2.8 | ISO-100 | Shutter 1/610 sec."
