There is no direct public transport link from the airport. The taxi journey from Rennes Saint-Jacques Airport to Telecom Bretagne campus takes 20 to 30 minutes.
However, it is possible to take Bus lines 57 or 33b from the "Gautrais" bus stop, situated about 800 metres from the airport (10 minutes on foot). Line 33b goes to the Beaulieu campus (terminus- Beaulieu/Restau U) and the stop is a 15 minute walk from the Telecom Bretagne campus. Or take line 57 to the République stop and from there take line 16 (Beaulieu Atalante) as far as the terminus and the campus is a 5-10 minute walk away.
