The Cayo is the most spectacular in Los Roques. It's a hasty statement, because of all the many islands, islets and sand banks that make up the archipelago of Los Roques. But the Cayo de Agua is the closest thing to the "perfect beach" I've seen in my life. It is ranked as one of the top 5 best beaches .... The best thing is how little the area is exploited. Even in high season (Easter) our experience in Los Roques was to "choose your little island, put your umbrella in and enjoy the Caribbean". The sand comes from coral and is so white that sunglasses are needed to walk around. The sea is a clean turquoise.
