1 Make for the entrance to the Science Centre, cross Wartling Road to a stile and enter the extensive woodland. Go over several tracks and continue on the straight footpath, picking your way through the trees. Eventually you reach a stile. Turn left, then immediately left into Wood Lane.
2 Follow the road alongside trees and cut between houses as you approach the road junction. Cross over to a bridleway sign among the trees and go through a galvanised gate. Walk ahead along the concrete path as it threads its way through the woodland. Pass a reed-clogged lake and begin a gentle ascent between the trees. Keep ahead along the wide footpath, passing beneath the boughs of some fine beech trees and, when you emerge from the woodland, make for a galvanised gate.
3 Head diagonally left across the field to reach a path. Keep left and veer left at a waymark after about 80yds (73m). Cross the field, heading up the slope to a line of trees. Look for an opening in the fence and follow the level path through the woodland. Cross over a path and continue on the bridleway to the road.
4 Turn left and head for Herstmonceux church. Continue along the road to a gateway, joining forces now with the 1066 Country Walk. Bear left and follow the concrete drive to a gate by the entrance to Church Farmhouse. Cross over a tarmac lane serving the study centre and, as you descend the slope, the domes of the old observatory begin to peep into view above the trees, giving these rural surroundings an unexpectedly surreal, almost futuristic quality. Make for the next galvanised gate and here you get an impressive view of Herstmonceux Castle over on the left.
5 Pass over a footpath crossing to another gate. Begin a gradual, though not particularly steep, climb and continue on the 1066 Country Walk as it runs hard by the Science Centre boundary. Follow the woodland path to the road, turn left and return to the lay-by.
