Grajau State Park protects a 55-hectare remnant of Atlantic forest in Rio's North Zone, with trails, rocky slopes, and views toward the surrounding neighbourhoods. The park is known for Pedra do Andarai, a granite outcrop that gives the area its most recognisable landmark.
It is a local, green counterpoint to the city's famous beachside sights. Go for a short walk, birdlife, and a quieter look at Rio's forested hills, rather than for big-ticket monuments.
