GRACE BAY BEACH, PROVIDENCIALES, TURKS AND CAICOS ISLANDS: Awarded Travelers' Choice for #1 BEACH IN THE WORLD is Grace Bay Beach. Grace Bay's white, sugary sand beaches stretch for 12 miles great for long walks. The clear, clean waters with shades of blues and greens are absolutely stunning. The diving and snorkeling are spectacular thanks to the third largest coral reef system that's easily accessible from the shore. The reef also breaks the incoming surf to create the calm waters. Perfect destination for beach lovers, water sport enthusiasts, couples and families alike.
