1 From the village, walk up the road towards Masham. Just beyond the speed restriction sign, turn right over a plank bridge by the Woodland Trust sign. The path winds through the wood, and down stone steps. Ignore a stile on the left and continue down into the woods, alongside a gully. You are now in Hackfall Woods.
2 Eventually the path takes a sharp right fork into the valley bottom to meet a main path, signed 'Ripon Rowel Walk'. Follow the path left across the stream, then take a right fork across a footbridge to see the River Ure on the right. This is one of the most spectacular stretches of the river, where it passes through a narrow gorge - a mid 19th-century guidebook spoke of 'the abyss at your feet, where the black waters sleep in cavernous gloom.'
3 Go through a gate, across a tiny footbridge, turn right through a gate in a wall and go back into the woods. The path rises and comes out of the woods at a signed gate. Go along the grassy track up to another gate and turn right along the track to reach farm buildings. Turn left, taking a track towards the road. At the top of the track turn left along a grassy track parallel with the road, and eventually join it. As the road bends left and the wood starts, go through a gate on the right with a Forestry Commission notice on it. Just after the gate, take a grassy track on the left, up through the wood to reach a stony track. Go left for a few paces, then continue uphill on the grassy track, to cross another stony track and bend slightly right to continue up the grassy path. At the edge of the woodland you will meet a track going left. Follow this track left for about 100yds (91m), then turn right down towards a small gate at the edge of the field.
4 Follow the path half left towards the top of the hill to a stile. Continue along the field side, with a hedge on the left, to another stile in the hedge. Go diagonally right across the field with a trig point to the left and over two more stiles. Near the trig point you may be able to make out the angle of the earthworks marking an early farming enclosure; its age has not been accurately determined. There are also wide views - Roseberry Topping is visible in clear weather. Go diagonally to the opposite corner of the field, veering away from the buildings to reach a road through two stone posts. Turn left along the road back to Grewelthorpe, where you might reflect on the 19th-century guidebook's words 'To those who are gladdened by the works of Nature, and a ramble in an umbrageous retreat, there cannot be afforded a richer treat than a trip to Hackfall.'
