Paris to Bayeux by train

SNCF is the national rail operator in France and not so long ago it recently simplified both the range of tickets and the term and conditions of using them.
Therefore the cheapest tickets also become more flexible too.

Other improvements included a simple integration of travelling with bicycles and rail pass users being able to book reservations for national journeys, without paying booking fees.

Though a legacy of when SNCF sold international tickets under the Rail Europe branding is that OuiSNCF is available in multiple translations with the offerings on the site then tailored to international visitors to France.
However, some of the site's features, including the integration of mobility assistance into the booking path, are only available on the French language version.

Something else to look out for is that simplest way of travelling with tickets is to use the SNCF 'My Travel' phone app, so it's therefore often a good idea to book on the OuiSNCF mobile service.
