Grumari

Rio de Janeiro, RJ, Brazil
🌀Strong rips

Grumari is Rio de Janeiro's most pristine surf beach, an environmental reserve where big wave legend Carlos Burle has called his favorite local spot. The beach is protected from development, creating a natural sanctuary just an hour from the city center. The waves are versatile, handling various swell directions and producing both lefts and rights along the beach. Access is controlled and parking limited, which keeps the crowds manageable even on good days.
