If you have only a few days to spare, your best option is flying directly into Rio de Janeiro and remaining in the area instead of using your precious time to travel further afield. After all, with sights as exciting as Corcovado, Sugar Loaf, Copacabana, and Ipanema, the magnificent city will easily occupy your time – and if you’d like to experience the rainforest, you can head to the nearby Parque Nacional da Tijuca.
