Another good activity is to go for a hike or a climb. The Tijuca National Forest is the best option is you are an outdoor nature lover. There are many medium to difficult trails available in the forest to enjoy a good hike. If you enjoy rock climbing then the mountains of Sugar Loaf and Corcovado are famous for this purpose. If you are adventurous and like to take risks then you can try Hang Gliding at Sao Conrado which is the jumping off point. You can get an aerial view of Tijuca National Park and the beaches of Rio as you soar in the air.
