We went on a wreck dive - it was an old WWII sunken ship near the boat docks. We saw old helmets, guns, ammo, pots & pans, cannons, and all sorts of fun things....
We went on a hike up and over a coral -laden hillside and back down the other side to a fresh water lake that is the home of billions of jellyfish. They no longer have the ability to sting, so it was safe to get in and swim/snorkel among them - it was AMAZING!!!
