Bus: Bus system in Rio is kind of complicated, the
busses have their final destination written on the top and the route that it
goes to get to the final destination is difficult even for locals that
sometimes have to ask the driver if the bus stops at the desired point. The entrance is on the front and the drivers
think they’re formula 1 pilots, so hold on tight! Besides that are often
reports of robberies in busses.
Cost: R$2,20 (1USD)

Taxis: Taxis run on
meters and most are reliable, the only problem is that 99% of the taxi drivers
only speak Portuguese and don’t have a previous guiding formal education, mostly not
giving reliable information on the visited spots.
Costs: 04hour at disposal
R$260,00 (118USD)
08hour at disposal R$520,00 (236USD)
According to Transcoopass, taxi company.

Organized Tours: Most of the organized tours are done on non
private basis, that means you’ll seat in a bus for up to 44 people with most
different nationalities, and spend most of your time passing by a lot of hotels
to pick up more tourists before the tour really starts. In most cases the guide
will give the information in English, Spanish and Portuguese thus making their
speech as short as possible.
Costs: 08hour tour R$270,00 (135USD) per person.
