Blending Caribbean charm and Central American character, Belize may be best known for its laid-back palm-fringed beaches and islands. Still, there’s plenty more to this small but sweet country—including ancient Maya ruins, labyrinthine caves, and an underwater wonder world second only to Australia’s Great Barrier Reef. While some of the best things to do in Belize are centered around Caye Caulker and Ambergris Caye, like snorkeling, fishing, partying, and diving the Blue Hole, the mainland has plenty on offer, too, from epic archaeological sites to ATV or horseback riding, and jaguar-spotting tours through the jungle.
