R$5,20 on Trensurb can be the cheapest first leg inland
Viagem de Ônibus Intermunicipal Estação Aeroporto really means “mix metro plus coach” rather than a single through-bus from POA. From Terminais 1 e 2 you ride the free Aeromóvel (under 5 minutes) to Estação Aeroporto, join Trensurb toward Mercado or São Leopoldo, then connect to a state-run intermunicipal coach at a rodoviária like Porto Alegre, Canoas or São Leopoldo.
Most intermunicipal lines to Gramado, Canela, Vale dos Sinos or Serra Gaúcha do not start at Estação Aeroporto; they leave from Rodoviária de Porto Alegre or suburban terminals. Travel blogs quote locals saying it is “mais fácil pegar Trensurb até a Rodoviária” than trying to chase a through-bus from the airport, and they are right: you’re usually looking at one metro ride plus one coach ticket.
Expect Trensurb headways of around 6–10 minutes in the day, with a single ticket near R$5,20, then coach fares that vary from about R$15 to over R$80 depending on distance to places like Novo Hamburgo, Gramado or Caxias do Sul. That combo often beats the cost of a taxi from POA into town, especially for solo travellers working in reais rather than on an expense account.
Frequency is the catch: late-night intermunicipal departures are limited, and posts on Viaje na Viagem mention travellers forced to overnight in Porto Alegre when their flight lands after the last coach. If your arrival into POA is after 21:00, pull up the rodoviária timetable before you book the flight or be ready to pay for a hotel near the Centro.
How to use Estação Aeroporto plus intermunicipal coaches
- 1. On landing at Terminal 1 or 2, follow signs to the Aeromóvel; the ride to Estação Aeroporto takes about 2–3 minutes and is free.
- 2. At Estação Aeroporto, buy a Trensurb ticket (around R$5,20) and board a northbound or southbound train: south to Mercado for Rodoviária de Porto Alegre, or north to cities like Canoas and São Leopoldo.
- 3. For Serra Gaúcha (Gramado, Canela, Caxias), regulars go Aeromóvel + Trensurb to Mercado, walk to Rodoviária de Porto Alegre in under 10 minutes, then buy an intermunicipal ticket timed to a specific departure.
- 4. For Novo Hamburgo or Vale dos Sinos, commuters often ride Trensurb past Canoas to São Leopoldo and then board a shorter intermunicipal leg from that rodoviária, which cuts both the fare and the waiting time.
- 5. Check company sites for the last bus of the day; some lines toward the interior stop around 20:00–21:30, so a 22:30 arrival into POA often means staying in Porto Alegre until morning.
One practical tip: print or screenshot the exact bus company, terminal name (Rodoviária de Porto Alegre, Rodoviária de São Leopoldo, etc.) and departure time before flying; that saves you from sorting routes on a weak airport Wi‑Fi signal at 23:00.
