Lagoa Rodrigo de Freitas is a kidney-shaped lagoon. Covering less than a square mile, it is a blend of fresh water and sea water from the Atlantic Ocean. Many people call it The Heart of Rio de Janeiro. Encircling the lagoon are high-rises, a 4.5 mile walking and cycling path, water sports clubs and parks. The Lagoa neighborhood is affluent – among the most expensive in South America. This is in sharp contrast to the slums of Rochinha built on the backside of the hill shown here. Off camera to the left is a unique perspective of Corcovado Mountain.
