Cheapest daytime ride from TAB to Scarborough if you’re patient
The PTSC bus runs between Crown Point and Scarborough along Milford Road, with the airport sitting a short walk off that corridor. Journey time on the bus itself lands around 30–40 minutes, but door-to-door from the terminal to central Scarborough can stretch to 45–60 minutes once you add waiting and the walk from the stop.
You won’t board at the terminal door at A.N.R. Robinson International Airport. To catch a PTSC bus, you walk out from the airport access road to Milford Road, then flag a bus heading toward Scarborough or Crown Point, depending on your direction. Travellers on TripAdvisor consistently describe this as a local commuters’ route first, airport link second.
Fares on the PTSC Tobago routes are low by island standards, which is why backpackers and solo travellers with one small backpack or carry-on put up with the extra hassle. The trade-off is time: buses run roughly hourly in daytime, and several TripAdvisor reports mention waits of over an hour on Sundays and public holidays.
Service is daytime-focused. On a standard weekday or Saturday, you see roughly one bus each hour on the Scarborough–Crown Point stretch, while on Sundays and public holidays the gaps are longer and less predictable. Multiple visitors note that PTSC timetables are treated as “guidelines,” not strict departure times, especially later in the afternoon.
Buses are not timed to flight arrivals at TAB, so landing at 14:00 does not mean a bus at 14:15. Regulars point out that you could step out to Milford Road and find you’ve just missed one, then stand 40–60 minutes for the next. Build the buffer if your Scarborough accommodation expects you at a specific time.
Peak local commute times around 07:00–09:00 and 15:00–17:00 see buses fill up quickly between Crown Point and Scarborough. Several travellers mention standing in crowded aisles and struggling to fit even a small suitcase, so this option works best if you carry just one backpack that can sit on your lap.
Many frequent Tobago visitors skip PTSC for airport runs and instead use shared route taxis on Milford Road marked “Scarborough” or “Crown Point,” which they say pass every few minutes in daytime. If you still want the absolute rock-bottom fare of the PTSC bus, step 1 is to clear customs, step 2 is walk out to Milford Road, and step 3 is be ready to let one or two full buses go by before you get a seat.
Practical tip: Landing after 18:00 or on a Sunday evening at TAB? Don’t gamble on the PTSC bus; grab a route taxi or regular taxi so you’re not stuck waiting in the dark on Milford Road.
