Belize proves the cliche that big things come in small packages. This tiny Central American country has the longest continuous barrier reef in the Western Hemisphere; the largest known classic Mayan city, Caracol; and the highest concentration per square mile of the largest new-world cat, the jaguar. It also has one of the most extensive and easily accessible cave systems for amateur and experienced spelunkers alike, as well as a nearly endless supply of some of the world's best snorkeling and scuba-diving opportunities. Depending on your personal preferences, you can choose to stay in an intimate and luxurious hotel, an isolated nature lodge in the heart of the Mundo Maya, or a tent on your own desert island. Or you can sample all three. The best part about all these world-class places and experiences is that Belize's compact size makes it easy to sample a wide range of them in a short period of time. The lists in this guide should help you zero in on a few personal bests of your own.
