With pristine beaches, verdant rainforests, and Mayan ruins, Belize may be small but it sure packs a punch. While most visitors come to relax on picture-postcard islands or go adventuring through the jungle on the mainland, Belize tours make it easy to get the best of both. From swimming with shark rays and island-hopping boat trips to river kayaking adventures, cave tubing, and trekking to remote temples, tours are the best ways to explore—and experience—Central America’s second-smallest country.
