We wouldn't suggest you travel to Beauvoir by bicycle - but it easily accessible by either:

 

Car:        7 hours from Calais

                4.5 hours from St Malo

 

 

Plane:    Bordeaux Airport - 1.5 hours 

                La Rochelle - 45 mins 

 

Travelling mid week reduces the cost and time of travel and reduces the impact of the French bank holidays which can increase time on the road.
