Floresta da Tijuca

New York has Central Park; Rio has the Floresta da Tijuca, a vast swath of rainforest with hiking trails, sparkling waterfalls and abundant greenery. There are a number of fine walks, as well as climbs up rocky 900m peaks, where rewarding views await. If you prefer flying to walking, take a hang-gliding flight from Pedra Bonita inside the Tijuca boundaries for a magnificent (if somewhat terrifying) view over Rio's wondrously green backyard.
