Jersey is a lovely place though - shame about the catamaran sea crossing!!!!
We took the car over in 2004 for a re-enactment event at Gorey castle. It was paid for by the organisers thank goodness. Would love to go back, but as tent campers I hope it would be easier?
Sorry, but your Swift Challenger 530 may well be too long to meet the length restrictions for Jersey. It's not a caravan friendly place - and the rules are strictly applied. Try France instead - ferry is cheaper, it's caravan friendly, and you can take as long a van as you want, and go where you please! You can even find a site on the Cherbourg peninsula and get a day trip to Jersey if you must!
Don't forget to leave a review of the French and other European campsites you have visited!
