It's now £15 pppn. Tidy compost toilets and a shower. Small tents can pitch in the woods and around the lake (but there is a LOT of goose/duck poop by the lake) Larger tents can use the big field, you'll need to carry your stuff quite a way though. Camper van spot by the lake, one near the entrance and another on the road leading up to the entrance. You can easily walk to the reservoir from here.
