Big attractions. Small crowds. Ambergris Caye is the largest island in Belize and features the area's best nightlife and local dining. It's also right next to the largest barrier reef in the western hemisphere. Not to mention, you can swim with whale sharks. It’s safe to say that Ambergris Caye has some big attractions. But if that’s not your thing, there are plenty of smaller things to do. Like, taking little naps on the beach or making small talk with the locals.
