getting to the beaches in the baía de sepetiba (sepetiba bay) can take two hours each way from rio's zona sul, and we recommend starting the day very early due to intense traffic.

for first time visitors, the best way would be via taxi, which could be expensive unless divided 4-way - the maximum number of passengers allowed in a taxi. 

an average taxi ride will be about 90 minutes each way, and could total about 300 reals roundtrip.

while by bus, average travel time is about 120 minutes each way, at a roundtrip cost of about 30 reals per person, depending on the buses used.
