How to get your bike to the Route des Grandes Alpes
Whether you’re travelling with TGV INOUI or TER, find out whether you can take your bike aboard your chosen train and any connections you may have.
You can reserve a space for your bike aboard select TGV INOUI trains for just €10. Search for “ticket + non-disassembled bike”. If you don’t get any results, the train you’re trying to book has no dedicated storage area or has no more available space.
You can search for another train, or simply disassemble your bike and take it aboard in a bike bag. There’s no extra charge, and you don’t need to book space for it. The only requirement is that the folded bike cannot exceed 130 cm x 90 cm.
Your bike travels for free. Simply hang it up or place it in the designated area aboard any TER train in the Auvergne-Rhône-Alpes. IMPORTANT: you cannot book space in advance. The bike area is available on a first-come first-served basis. We recommend avoiding peak periods and arriving around 20 minutes before departure to be ready to load your bike.
TER Sud Provence-Alpes-Côte d’Azur
IMPORTANT: for reasons of safety and capacity, you cannot take a fully assembled bike aboard a TER Sud Provence-Alpes-Côte d’Azur train at peak periods, Monday to Friday 07.00-09.00 and 16.30-18.30. Outside these periods, your bike travels for free. Simply hang it up or place it in the designated area. No advance bookings are accepted, and the bike area is available on a first-come first-served basis.
A TER SUD coach can carry up to 3 bikes in its hold, if space is available.
