Some of the best diving in the world are found off the shores of Belize, including the world-famous Blue Hole. The abundance of great diving, snorkeling, and fishing are related to Belize’s Barrier Reef located less than a mile from Ambergris Caye, which is the second-longest reef in the world. Water visibility commonly reaches 100+ feet and water temperatures average 80 degrees Fahrenheit, contributing to the overall ideal conditions for great diving and snorkeling.
