Grafham is a small and compact, but we really enjoyed our time here. Ideally placed for Grafham Water which is great for walking and cycling. It can get very busy at weekends, so if you intend doing the circuit weekdays are best.. Its about 10 miles/3 hours and worth the effort. There are also plenty of farmland walks for those with less energy Cambridge is about 30 mins drive and a joy to walk around. I must commend the wardens here. During our stay, a caravan that was leaving had an electrical fire, and their reaction was of the highest standard. They were there in a flash with extinguishers, and soon had the caravan isolated on an open area of grass. Also, we had some very high winds and rain on one night, and saw the warden walking the site and pushing in awning pegs that had come loose. Excellent.
