The goals were Sugarloaf and Christo Redentor. The obstacles were high taxi prices and a limited metro network.
Buses generally up the ante in confusion, and Rio at first is no exception, with a system in the main areas of BRS1/2/3 stops where buses only stop at 1 of 3 to keep things moving. We were surprised how generally well Rio traffic flows.
Those bus stops in the main tourist areas have handy route lists with icons of the well, iconic tourist sites of Rio. Hop on!
