Your choice of Ferry may depend upon a number of factors, where you live, how long a drive you want in France or whether or not you get seasick. Essentially, the main crossings are either the short sea Channel crossings from Dover or the Western Channel crossings from the South Coast ports. These are usually more expensive and longer but cut driving time in France.
For those who are worried about driving in France …..don’t be. The roads are of a very high standard and there is far less traffic than in the UK. Ok, so they drive on the wrong side but you soon get used to it.
