The second longest barrier reef in the Western Hemisphere and one of the marine wonders of the world is the Belize Barrier Reef. This wall alive with millions of coral organisms spans Belize's 185 mile coastline and provides for many locations from which to experience Belize's underwater garden. Marking its location in the Caribbean Seas is a chain of white surf. Beneath this surface, the Belize barrier reef treats divers to a rich ecosystem that includes hundreds of animal and plant species.
