Ian Gongona created this marvelous video of a tiny island off the coast of Luzon in the Philippines. Not to be confused with an island of the same name near the Caribbean island of Anguilla, it's located just to the north of Marikiban Island in Balayan Bay. The entire area is part of the Batangas region of western Luzon. For semi-obvious reasons, it's also known as Sombrero Island. Barely visible on a map, the tiny island (which does indeed resemble a hat) sparkles in the bright blue sea.
