There are many ways to cross the channel as many ferry companies connect South of England to France. From the harbour of arrival you have an excellent connection to the road network of France. For example from Calais it is about 740 km to our holidayhouses in Dordogne, Bussiere Badil.
Or from Le Havre it is about 540 km. From Caen it is 490 km.
Or you can choose to take the eurotunnel and arrive to Calais.
