The site on the cover is Park Cliffe Caravan and Camping Estate, between Newby Bridge and Windermere, just off the A592. The photo was taken at the summit of the adjacent hill (Moor How) which is accessed from a footpath which starts alongside the touring pitches. The water visible in the background is Windermere.
