The harbour of Rio de Janeiro is comprised of a unique entry from the ocean that makes it appear to be the mouth of a river. Additionally, the harbor is surrounded by spectacular geographic features including Sugar Loaf mountain at 395 meters (1,296 feet), Corcovado Peak at 704 meters (2,310 feet), and the hills of Tijuca at 1,021 meters (3,350 feet). These features work together to collectively make the harbor one of the Seven Natural Wonders of the World
