Siesta Beach stretches from a site named Point of Rocks, just below the middle point of Siesta Key, north to the Siesta Village region.
It might be considered Siesta Key’s premier claim to fame. Siesta Key's Siesta Beach has accumulated numerous awards in recognition of its soft, clean, pure-white sand (see awards list below). Currently it is #1 among the top ten beaches of Florida, the U.S., and the world.
Harvard University's geology department found the sand of Siesta Beach was 99% pure quartz. Unlike most beaches that are composed of crushed shells, rocks or lava, this sand is pure white and finer in texture than most refined sugar. The sand has been described as "dazzling" and it is stated that it never feels hot. Siesta Key's remarkable sand and the azure, warm water of its beaches are a great attraction for tourists and local beachgoers alike who come to experience the sand and the water.
