62 Best Sights in Rio de Janeiro, Brazil

At the far end of Barra's beachfront avenue—the name of the street was changed a few years back to Avenida Lúcio Costa, but locals still call it Sernambetiba—is this 1-km (½-mile) stretch of sand anchored by a huge rock that creates a small, protected cove. Recreio's quiet seclusion makes it popular with families. Although busy on weekends, the beach here is wonderfully quiet during the workweek. The calm, pollution-free water, with no waves or currents, is good for bathing. But don't try to swim around the rock—it's bigger than it looks. Amenities: food and drink. Best for: swimming; walking.

The juxtaposition of the "haves" and "have nots" couldn't be starker, or more startling, than it is in São Conrado, where mansions and expensive condos sit right next to sprawling favelas. As you approach the neighborhood heading west from Ipanema, Avenida Niemeyer, blocked by the imposing Dois Irmãos Mountain, snakes along rugged cliffs that offer spectacular sea views on the left. The road returns to sea level again in São Conrado, a natural amphitheater surrounded by forested mountains and the ocean. Development of this upper-class residential area began in the late 1960s with an eye on Rio's high society. A short stretch along the beach includes the condominiums of a former president, the ex-wife of another former president, an ex-governor of Rio de Janeiro State, and a onetime Central Bank president. The towering Pedra da Gávea, a huge flattop granite boulder, marks the western edge of São Conrado. North of the boulder lies Pedra Bonita, the mountain from which gliders depart.
