USA is well known for beautiful beaches. Where are the best ones though? Environmental scientist Stephen Leatherman, known as "Dr. Beach” has been ranking the most beautiful beaches in the USA every year since 1991. Fifty criteria are used to evaluate all the beaches. These include water and sand quality, environmental noise, public safety, and the beach's environmental protection and waste disposal management practices. Half of the top ten beaches in the U.S. are in Florida and Hawaii. Tourism Review presents the winners.
