We have stayed here a lot of times.  It is convenient, as we arrive on Eurotunnel and often about 7pm, so I can book the site in advance, as in August it can be full.  Once set up, we always walk in to the town, and then come back and have a beer in the site bar, which almost makes it feel like we have arrived in France.  I say almost, as there is too much English being spoken to feel like real France, but it is close. Pitches are good, facilities are fine and the staff are friendly.  It makes a great overnight stop as we arrive in France. However, a lot of people have their whole holiday here.  If you have never been to France before, it gives you the chance to try it out.  It is a nice site for a longer stay, and the area is very nice.  Great beaches, nice scenery and Calais itself has some interest. There a lot of things to see and do in a fairly small area.
