Basic campsite, not too big toilets, three showers, basic shop with limited hours. Run by the National Trust, so not manned all the time. Cheapish rates, currently £6 per pitch plus £6 for additional adults. Great location a short walk from the lake, and a longer but easy stagger back from the pubs in Coniston village.
Might be a midge problem in the summer being close to the lake, but can't confirm that.
