A haven for leisure and adventure lovers, Belize is a stunning country situated on Central America’s eastern coast. It’s bound by a rich forest to the west and the Caribbean Sea to the east. The location is home to Mayan ruins, amazing wildlife, waterfalls, islands, and more to explore during your stay. Begin your journey from Xunantunich, an ancient architectural wonder on artificially flatted limestone. A swim across a turquoise pool leads to Actun Tunichil Muknal, a cave with spectacular rock formations. Also, learn about the rearing, hatching, and incubation of iguanas at the Green Iguana Conservation Project.
