1 Start by following the Riverside Trail, clearly signposted from the information office and toilet block. The trail takes you down to the banks of the Little Ouse River, that divides Suffolk from Norfolk. After about ½ mile (800m) the trail turns away from the river between areas of woodland and meadow. When the trail turns sharp left after crossing a footbridge, leave the Riverside Trail and go half-right instead, to head towards the woods.
2 Now you are on the green Heathland Trail, though frustratingly the waymarking posts are only marked on one side and you are walking in the opposite direction. Turn left at a junction of paths and continue down to the road along the western boundary of the park. This is the end of the Peddars Way, a long distance trail that follows a Roman road to the North Norfolk coast, and the start of the Icknield Way, possibly the oldest route in Britain. Cross the car park and continue along the path that soon arrives at open heathland covered with purple heather in summer. Turn left along the edge of a line of fir trees and bear left, still on the green trail, around the edge of the heath. Turn right at a junction of paths to reach the remains of an 18th-century rabbit warren. Keep straight ahead at a crossroads and continue to the end of this path, then bear left towards Hut Hill, a Bronze-Age burial mound that dates back to 2000 bc and is easily identified by the lone Scots pine at its summit. Keeping the burial mound to your right, walk down the hill, then turn sharp right at a junction to join the yellow Woodland Trail. For a short cut you could keep straight ahead to return to the car park at this point.
3 You now stay on the Woodland Trail for the remainder of your walk as it weaves its way through the woods past silver birch, oak and Scots pine. The path briefly joins a horse route and passes a barrier to reach a road. Cross the road and continue on a path to your left. Towards the end of the trail you pass an area of grazed heathland where Exmoor ponies and Hebridean sheep are kept. Cross the road again, turn right through a woody glade and continue to the car park, where there is a small playground and a weir where children splash about in the river.
