The small Aeroporto de Rio Branco is 22km northwest of town on Hwy BR-364.
GOL Three daily flights to/from Brasília, and one to/from Porto Velho.
LATAM Two daily flights to/from Brasília, with extensive onward connections.
A taxi to or from the airport costs an eye-popping R$100. Alternatively Bus 304, signed as ‘Custódio Freire,’ runs between the airport and town roughly every 45 minutes (R$3.50, 45 minutes, 5am to 11:30pm).
The Rio Acre is navigable all the way to the Peruvian border at Assis Brasil but there’s little river traffic (and none that follows a schedule). Headed the other direction, it’s possible to catch a boat down the Rio Purus from the town of Boca do Acre, north of Rio Branco, theoretically all the way to Manaus. That said, if Manaus is your destination, there’s a much more frequent and reliable boat service on the Rio Madeira, leaving from Porto Velho.
Long-distance buses leave from the Rodoviária Internacional de Rio Branco, a sleek new bus terminal 8km southwest of town. Petroacre has services to Xapuri (R$38, 3½ hours, 6am and 1:45pm), Brasiléia (R$48, four hours, 6am, noon and 2:45pm), Assis Brasil (R$60, six hours, 6am and noon) and Cruzeiro do Sol ($128, 12 to 14 hours, 7:15am and 7:30pm).
