For those who have no experience diving, there's snorkeling. Except for very young children, there is no age limit. All you need is a snorkel, a mask, and flippers (which you either purchase at home or rent right here in Belize), and you're all set. You can jump in the water right away with an instructor and witness the most astounding underwater plant and animal life in the Caribbean. For the advanced, diving is the way to go. Frolic with a school of dolphins, be awed by the hundreds of species of coral, and even explore a sunken shipwreck. The best snorkeling and diving sites include Ambergris Caye, Turneffe Islands, Lighthouse Reef, and Glover's Reef.

Now if you would rather cast into the saltwater than be in it, then you better go fish. Literally. All kinds of fishing--spin, fly, trolling--can be experienced year-round. Blue crystal-clear waters teem with game fish such as bonefish, permit, and tarpon, which have grown accustomed to a rich diet of shrimp and crabs. Within a few minutes of leaving the dock, you will find yourself casting away in either the cool, shallow waters of the tidal flats or navigating the atolls hundreds of feet deep in a boat.

Oh, and did we mention you could go kayaking, sailing, windsurfing, jetskiing? Resorts offer both half-day trips and whole day excursions. And for those who want to relax and just soak up the rays, there's always relaxing on the deck of a glass-bottom boat or a raft.
