It is also called Siesta Key Beach. It is possibly the best sand beach in the world as it is 99% pure quartz! In 1987 at the “Great International White Beach Challenge”, it was regarded as having the “whitest and finest sand in the world.” Four years ago, Dr. Beach called it “The Best Beach in America.” Last summer, my wife and I visited the place. The beach isn’t just beautiful; the people, too. If you love the beach, you’ve got to go.
