  • Snorkeling at the Great Blue Hole, activity organized by Island Expedition during our stay at Light House Reef was priceless.  more »
  • This is a very unique dive. Starts at 90 to 95 feet and max depth is recreational limit. At 90 feet the sheer wall cuts back about 25 to 30 feet and you swim around huge stalagmites and stalagmites...  more »
  • Grandpa's Garage Studio 7 suggests to get over here and get healthy. Swim in there at your own risk. Due to currents you may get sucked in, best is to stay outside the center and stay together. This is formed when giants were stuck in the mud and could not move, this was a giant animal, no doubt. Our stones, earth and geology are all formed by mud and turned into stone, gems and are all fossils.
  • If you like diving and want to embark on a adventure, this is the place to go. I highly recommend it! It's far offshore so it'll probably take a full day. It's a deep dive in which you will go through layers of sediments and dive into the dark where a few sleepy sharks can be spotted. Once at the max dive depth, you'll see giant stalactites from the time this was a cave. It was a very special experience and unique dive. 👍
