Tijuca National Park (Parque Nacional da Tijuca)

Tijuca National Park, a 13-square-mile (33-square-kilometer) expanse of Atlantic rainforest, is the world’s largest urban forest. Located in Rio de Janeiro, Brazil, it stands as a remnant of the vast jungle that once surrounded the city before the 19th century. The park is a dense tangle of tropical trees and jungle vines, providing a habitat for ocelots, howler monkeys, and over 300 bird species. Visitors can explore its lush trails, discover waterfalls, and even catch a glimpse of the iconic Christ the Redeemer statue atop Corcovado Mountain.
