Rio is a fairly easy city to navigate, with an efficient metro system, a public bike-sharing system and hurtling buses. The neighborhoods themselves are perfect for getting around on foot.
Minivans (called vans in Rio) are an alternative form of transportation in Rio and usually much faster than buses. They run along Av Rio Branco to the Zona Sul as far as Barra da Tijuca. On the return trip, they run along the coast almost all the way into the city center. They run frequently, and cost between R$2.50 and R$5. They do get crowded, and are not a good idea if you have luggage. Call out your stop (para!) when you want to disembark.
