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.
