A lesser-known gem in Belize, 15-acre South Water Caye is our version of an off-the-beaten-path destination (though most places are here) for diving and snorkeling, not to mention relaxing on one of our best tropical beach settings in the whole country. The southern section is well known for its sandy beach, and since the reef is only a short swim from the shore, you can split time between relaxing on the beach and taking in underwater life. Which activity you spend more time doing will be a tough decision.
