We visit the area regularly to visit family and initially avoided Northfield because of the Railway line seen on google maps but after a few disappointing stays on other sites we decided to give it a try and wish we'd done it sooner - Northfield is the best site we have found in 30+ years caravanning! The site is perfect for dog owners being surrounded by public footpaths. Sainsburys supermarket at the end of the road. Excellent Gastro Pub nearby at Hampton Poyle. Good links to the area. The list goes on.... We are now regulars and spend as much of our time here as possible. The bridge and last section of road referred to by some is being removed and a new access being created soon I understand although I have never had an issue with a huge 4x4 and twin axle. My only worry is everyone finds out how good it is and I can't get in because it's full....
