Belize is best known for its lush rain forests, Mayan ruins, and gorgeous barrier reef -- one of the world's best sites for snorkeling and scuba diving. As so much of the country's tourism is dependent on its breathtaking natural surroundings, a determined commitment to eco-friendly practices can be found in most hoteliers, and Oyster has stayed in everything from compact eco-lodges to rustic-luxe hideaways during our visits to this small South American country. Here are our favorite eco-friendly stays: First up is the Xanadu Island Resort, a simple, relaxed property with 18 spacious units on a lovely stretch of beach along Ambergris Caye, just minutes from central San Pedro. All of the domed buildings are energy efficient and the owners have continued to make the property more sustainable over the years. They have also won the First Green Globe Island Certified Property in Belize by the International Center for Responsible Tourism in the past.
