Rodrigo de Freitas – Rio de Janeiro, Brazil

Located on the southern side of Rio, the Rodrigo de Freitas Lagoon is connected to the Atlantic Ocean by a canal. The lagoon is often referred to as “the heart of Rio.” While the water isn’t ideal for swimming, “duck boats” are available for rent to paddle around the lagoon. Bikes are also available. Longboarding and biking around the lagoon are popular activities, as well.
