1 On leaving the car park turn right and head towards the dramatic scarp of the South Downs. Pass Rackham Road and follow the lane into the village of Rackham. Keep on the road as it cuts between fields to reach a junction. Bear left here and follow the B2139 for about 75yds (68m). Turn right to join a bridleway and climb steeply, passing through a gate.
2 Continue the steep ascent, glancing back at intervals will reveal memorable views of Parham Park in the distance and, away to the west, the meandering River Arun. The path curves to the right and from this high ground much of the route of the walk can be seen. The village of Amberley, with its imposing castle remains, is also visible from this lofty vantage point. Make for a gate and join the South Downs Way.
3 Turn left, avoid the bridleway running off to the south, and head east. Pass a trig point on the right and continue ahead over this high ground. On a clear day you can spot the sea glinting in the sunshine. Pass through a belt of trees and continue to Kithurst Hill car park on the left. Branch off here by some double galvanised gates.
4 With the car park sign on the right, go foward to join a bridleway which initially runs parallel to the road. Follow the path to a gate, cross a pasture to a second gate and follow the path as it descends quite steeply between trees and undergrowth. Pass rows of conifers, join a track, avoiding a galvanised gate on the right, and go straight on. Pass alongside a line of trees and keep fields and downland on the right. Follow the track to a wooden gate leading out to the road by a house called Paygate. Cross over and take Clay Lane, passing Cootham Farm and Lower Barn. To visit Cootham and the Crown, turn right.
5 Walk back along the main road, avoiding Clay Lane. Make for the entrance to Parham Park, pass a stone-built lodge and go through a gate leading into the deer park. Follow the drive and when it curves gently to the left, join a parallel path on the right. Cross a pasture and look away to the south for a striking view of Parham House with the scarp of the Downs rising steeply behind it.
6 On reaching a junction of drives, head straight on towards Rackham. Pass alongside a stone wall and, beyond it, a lake looms into view. Continue through the gently undulating parkland and turn left when you get to the road by West Lodges. Pass a picturesque stone house and avoid a turning to Greatham and Coldwaltham. Follow the lane down through the trees, back to the car park.
