Dr Beach names Hawaii's Hanauma Bay the best in the US

When you come upon an ocean bay that has features known as "Toilet Bowl" and "Witch's Brew", you may not envision a welcoming tropical oasis.

But Hawaii's Hanauma Bay, nestled inside a breeched volcanic cone on the southeastern shore of Oahu, has some of the state's calmest waters, most pristine beaches and world-renowned snorkeling over coral reefs that teem with colorful fish.

For the second year in a row, a beach in Hawaii has been selected as the best beach in the United States by a Florida professor who has made a career ranking and studying beaches around the country. This year's top spot goes to Hanauma Bay, a picturesque nature reserve with gin-clear, turquoise water and abundant sea life.
