The nature reserve itself is a small fenced area lying under the power lines. Simply park in the main car park, follow the trails until you hit the power lines and then turn right until you come to a fenced in area, with interpretation panel and stiles. The ditch bank just north of the fence line is a good place to walk along looking for Adders, which bask in the sunshine among the tree roots. It takes about 15 minutes to walk to this place from the car park - although longer with young children!
