C6

EUR 1.50 into Rennes if you’re fine with a transfer

C6 works for T1 arrivals at Rennes–Saint-Jacques when you care more about cost than a straight shot into town; the in-vehicle time sits around 20 minutes but the whole thing depends on how cleanly you hit a metro and bus connection. The official single ticket on the STAR network runs about EUR 1.70–1.80, slightly above the base EUR 1.50 figure, and covers both bus and metro for 60 minutes, so 1 ticket can pay for the airport-area metro plus C6 if you move quickly.

C6 itself never pulls into the terminal forecourt at RNS, so build in a 10-minute walk plus metro ride from T1 to reach a stop on the C6 corridor such as “Henri-Fréville” or “Jacques Cartier.” From those stops, C6 gives you roughly a 20-minute ride into central Rennes, but headways vary from every 8–10 minutes in peak to every 15–20 minutes later in the evening, which can stretch the total airport-to-city time toward 40–50 minutes if you mistime it.

Figure daytime frequencies of every 20–30 minutes as a safe planning number if you are pairing STAR metro line A with C6 for an outbound flight from T1, especially in the 07:00–09:00 and 16:30–19:00 windows when Rennes locals describe the bus network as saturated. Standing-only loads are normal on C-lines at rush hour, and riders mention that real-time information on STAR screens and apps sometimes lags during traffic disruptions, so avoid cutting it closer than a 60-minute buffer before check-in closes.

Step-by-step: T1 to Rennes city centre via C6

• 1. Exit T1 and follow signs toward the “Saint-Jacques – Gaîté” metro area; expect around 10 minutes on foot depending on luggage.
• 2. Buy a STAR ticket (about EUR 1.70–1.80) at a machine; it stays valid for 60 minutes across metro and bus, including C6.
• 3. Ride metro line A toward Rennes centre and get off at “Jacques Cartier” or “Henri-Fréville,” both on the C6 corridor.
• 4. At street level, locate the C6 stop signs; peak headways can be as short as 8–10 minutes but plan for up to 20 minutes later in the day.
• 5. Board C6, validate the same ticket again, and stay on for roughly 20 minutes into central Rennes, watching the stop display because on-board announcements can be hard to hear in a full bus.

What regulars do and one last tip

Rennes residents often lean on metro lines A and B first and keep C6 for the last leg, since the underground runs better in traffic than surface buses on the C-corridor. Frequent users buy 10-trip carnets or a day-pass to bring the per-ride cost under the basic EUR 1.70–1.80 single; that pays off as soon as you stack a roundtrip plus one extra hop. For an early flight out of T1, check the first metro and C6 departures the night before and pad your schedule by at least one full headway on each leg.
