The length of two football fields, Prainha is a vest-pocket beach favored by surfers, who take charge of it on weekends. The swimming is good, but watch out for surfboards. On weekdays, especially in the off-season, the beach is almost empty; on weekends, particularly in peak season, the road to and from Prainha and nearby Grumari is so crowded it almost becomes a parking lot. Amenities: toilets; showers. Best for: swimming; surfing; sunset.
35 km (22 miles) west of Ipanema on coast road; accessible only by car from Av. Lúcio Costa (Av. Sernambetiba), Rio de Janeiro, 22785–250, Brazil
