Uk to France for a Newbie?

[daf.vinci]

Hi guys,
Me and my wife and kids have decided we are going to go on an overland trip at least once a year in our Landrover Discovery and are going to start small and build on our experiences every year.

This will be our first time abroad so any advise is very appreciated.

Our first trip is going to be from Wales in the UK to France and spend time visiting and camping in/close to their beautiful national parks and maybe a few brief visits to more populated places like Paris, Bordoux and Nantes to visit museums and that sort of stuff.

We are looking to spend 10 to 14 days initially so we have time to do lots of stuff, but don't find ourselves staying in the same place too long.

My main questions are:

What documents do we need if any (obviously passport is needed) ......

Is driving the same as this country (give way to the right,etc) apart from driving on the right side of the road and needing a hi-vis vest for every person on board.

Thanks in advance for any replies, and if there are any other things that will be relevant to our trip please feel free to comment.
