Lagoa Rodrigo de Freitas, Lagoa
Rio de Janeiro
Concierge.com's insider take:
Roughly behind the neighborhood of Ipanema lies this saltwater lake, usually just called Lagoa. Ringed by expensive apartment buildings and a 4.6-mile track for running, walking, and bike-riding, it's a great place to get exercise, hang out, or eat (you wouldn't want to swim here, though). In the evening, there are a number of decent kiosk-style restaurants serving sushi, Italian, and Middle Eastern food, and they usually feature live musicians at night.
