We've just got back from a lovely Easter Weekend at Body Farm.  It's a beautiful site that is maintained well by the owners. There's plenty a of space and the views are stunning. Access to the site is easy and the location is within 5mins from the M3 all on main roads.  We went as a party of two families, both with young children and there was plenty of space for them to run around and play without getting in the way of the other caravans.  There is a walk straight from the field, which I was told by another camper was a great walk. (We ran out of time to explore this) Easy asses to Southampton, Portmouth and other local areas.  Even though close ish to the road, a very peaceful site.  I will be booking this site for later in the year. :)
