3. Your favorite island has never looked so good. As soon as you jump from the lurching platform into the smooth, blue water, you'll feel the rise and fall of the waves slow to a gentle, lulling rhythm. And then, just as quickly as you sink below the surface, a new island noise surrounds. The shimmering shapes, only barely visible from the boat, begin to take shape. And the coral, which you may have seen gliding along the top of the water with a mask and snorkel, is now all around you. Schools of fish zip by in fluorescent blue, orange and red clouds, and myriad creatures scurry below on the ocean floor.
