campsites within staggering distance of pubs !!!

bonjour from l essex lounge!!!!....
this is all a bit last minute , but would any of you chaps or chapesses know of a semi~decent site i could go to on Dartmoor or Exmoor,within site of a watering hole ?
i m ending up down there the weekend after the A R , after upsetting the rest of the U K first ... Not too bothered about the cost and amenities,so long as there s a decent sized tree to stand behind
thank s and merci boucoupe .
