Ipanema beach is bordered by Arpoador Beach on one end and Leblon Beach on the other end. This beach is considered one of the main centers of activity for the city of Rio. One of the most expensive places to live, the neighborhood is full of wealthy residents.
The beaches of Rio de Janeiro are divided into tribes, but Ipanema is where that note is so strong. In front of the country club meet young beautiful and high class people. It’s certainly the place to see and be seen. In the Posto 9, near Joana Angélica Street the public is more laid back and alternative. The strip of sand between Ipanema and Leblon close to the canal is not very busy and it is quite empty, and should be avoided.
Frescobol is a sensantion among cariocas at the beach, it's like tennis, it's played by two people with racquets, not net and you are not to drop the ball. If you go to Ipanema don’t miss watching it and if you feel like participating also, it will be a pleasure for Cariocas to have a tourist playing with them.
