Boasting lush rain forests and top dive sites, Belize is ideal for adventures on land and sea. And with departures from most major U.S. cities to Belize City Airport and English as the country's official language, Belize is exceedingly accessible for Americans. A number of luxury resorts have opened in Belize in recent years. The 100-room Four Seasons Resort and Residences Caye Chapel is scheduled for a 2021 opening.
