1 Walk out of Castle Ashby along the road heading south westwards, with the house (and visitors' car park) over to your left. Where the pavement ends turn right for the hamlet of Chadstone. Drop down the lane past the cottages and expensive-looking converted barns and all the way out to the farm of Chadstone Lodge.
2 Turn left for the bridleway alongside the hedge and, at the end, go on through the trees to continue the route alongside the next field and down to a road. Cross over for a footpath down to Whiston Spinney, then via a footbridge in a lovely shady dell to reach a junction of tracks on the far side. Here go straight on, signposted 'Footpath via Jerusalem Steps', and cross a field to the trees on the far side.
3 Follow the path up the steps and out along a field edge with the woodland (The Firs) on your right. Beyond a gate go down a sharp flight of steps to the right and across a field in order to turn left on the far side and drop down to the road below.
4 The route continues up through the field opposite. Head half left, then follow the bridleway waymarks to the right, through a long narrow field with the houses of Cogenhoe on your left. At the far side join a lane and descend to Cogenhoe Mill.
5 Just before the old mill buildings and sluice, with the caravan park beyond, turn right for a path alongside the River Nene (signposted 'Nene Way'). Follow this pleasant waterside walk for 1 mile (1.6km) as far as Whiston Lock, then turn right for a straight farm track across the fields to the main road, heading towards Whiston church sitting astride the hilltop like a lighthouse.
6 Go across the junction and walk the lane into Whiston, branching left at the small triangular green. Take the gated passageway beside the outbuildings of Manor Farm up to the church. There are good views across the Nene Valley to Earls Barton and Wellingborough, and the eastern edge of Northampton.
7 Walk past the church to the far side of the churchyard, go over a metal rung in the wall and turn right on to an obvious field-edge path. This continues along a grassy strip between further fields and emerges on to the bend of a lane. Go straight on/left and walk this all the way back to Castle Ashby.
