1 Leave the car park and turn right on to the B1146. Take the next right, which is the Nar Valley Way, one of Norfolk's prettiest long distance footpaths. This takes you past a copse and then through Gressenhall itself. When you reach the Swan Inn turn right, past more houses, until you reach a crossroads. Turn left here, following signs for the Nar Valley Way.
2 After about 100yds (91m), take the footpath to your right, still the Nar Valley Way. This narrow path lies between tall hedges and is like a green tunnel in summer and spring. It widens eventually and, after about ¾ mile (1.2km), emerges on to a track called Stoney Lane. Turn left, still following signs for the Nar Valley Way, and walk for another ¾ mile (1.2km) until you reach a plantation of tall pine trees. Turn left, leaving the Nar Valley Way. The foundations of the deserted village of Bittering Parva are to the right.
3 When you reach a crossroads and Ostrich House, follow the lane towards Longham. At the next fork bear right, past Longham Village Hall Sports and Social Club, and walk along the wide street. Turn sharp left at the White Horse at Longham. Walk down a hill, then up the other side, with pretty views across working land to your right.
4 Once you have passed the barn conversions and a pair of silos, turn left at Park Farm Cottages, and walk for about ¾ mile (1.2km), ignoring the first lane to your right, and bearing right at the next junction. At the junction after that bear right again, following signs for Dereham, past the old cottages on your left. The road winds along a shallow valley until you reach a brick bridge and Norfolk Herbs at Blackberry Farm.
5 Turn left along the gravel track signposted to Drift Farm (public footpath) and follow the signs to the right before you reach the farm itself. When you reach a crossing of paths, take the one to your left, towards Beetley. The path traverses an orchard and can be very muddy. Eventually, some tall trees come into sight and you will see the outlying houses of Beetley village. When you reach the Stables and Mill House, turn left on to the main road. Walk along this lane until you see signs for the Roots of Norfolk museum on your left and follow them back to the car park.
