Travelers will have no trouble satisfying their thirst for adventure in Rio de Janeiro. The city’s craggy mountains, glittering seas, and famous landmarks aren’t just for admiring—they’re also for exploring. There are hundreds of rock climbs within an hour of the city center, and many of the granite towers provide the perfect springboard for hang gliding. Take a scuba diving or surfing class in one of the most beautiful bays in the world. Hikers can explore local parks or the wilderness surrounding the base of Christ the Redeemer. Feeling extreme? Contact a local parachuting group, and enjoy one of the most beautiful free falls possible.
