From Therfield village green walk down Church Lane and into the parish churchyard. Go through a gap in the railings to the south of the south porch and bear left on to a green lane, with the vicarage garden on the left and a field on the right. At a footpath post keep straight on along a grassy margin at the left of a field, then go across a field to a kissing gate. Cross pasture to another kissing gate, go through this and turn right on to a green lane, Duck's Green. Ignoring footpaths to right and left, the track bears left, now following the parish boundary. Where the path meets a track, turn right on to a green lane.

Follow this green lane, which soon turns right, climbing gently between ancient hedges. At a track junction go left and continue climbing, passing a footpath junction before reaching the crest of the hill. Ignore a track turning left – carry straight on along a loosely metalled track.

Further on turn right on to the bridleway, with a fence and paddocks to the left, arable land to your right. This becomes a track through arable land. At a bridleway post, where the hedge reappears on your right, turn right on to a green lane, soon hedged only on the left. At a post-and-railed sheep enclosure go left. Then, through a gate, turn left to another gate on to a lane and cross to the church lychgate.

Visit the St Faith's Church, entering through its original, heavy, 15th-century door. Leave the churchyard from behind the chancel on to a path between a fence and walls, signposted 'Hertfordshire Way'. At the lane turn left. At the road junction jink right then left to walk past the telephone box and the village hall, dated 1895.

Continue past Fox Hall Farm and a pond. Turn right at a footpath sign, just before a thatched cottage, on to a track initially between hedges, then alongside a patchy hedge. At the end of the field go through a kissing gate and, just before the footbridge, turn left. After a few paces, with the ditch on your right, turn right at a footpath sign. At the track go left to walk past the tall water tower. At the road turn right and follow it past Tuthill Court and some Victorian estate cottages. Turn right past Bell House into Pedlars Lane, which winds back to Therfield village green.
