1 At the bend in Ermine Street there are two footpath signs: follow the 'Ware' one steeply uphill to the Victorian parish churchyard, for good views northwards and westwards. Retrace your steps downhill to Ermine Street and follow the other footpath, signposted 'Thundridge Old Church'. After a kissing gate go straight on across pasture, now on the Hertfordshire Way, then cross some arable land to descend to the Rib Valley. Turn right on to a lane. Where it goes right carry straight on on to a metalled track. The ruined church tower is visible ahead and to the left, beyond the river, are the grounds of Youngsbury, a country house from 1745 set in 'Capability' Brown parkland.
2 Only the tower of the medieval parish church remains, the rest having been pulled down in 1853. Continue along the metalled track, between pastures. Where the track goes right, continue straight ahead, now on a footpath. Cross an access road. At a footpath crossroads go left over a footbridge that bypasses the River Rib ford.
3 Now climb out of the valley with arable fields to your right, Youngsbury's Picturesque parkland to your left. At the brow the track skirts woodland, in fact an arboretum. Carry straight on, ignoring the track bearing right. Go straight on, past some farm buildings. The track, now metalled, curves left and downhill.
4 By some white-painted, iron gates go sharp right across cultivated land, heading for a footpath post in front of some woods. Turn left here and head west towards the tower and spirelet of High Cross Church.
5 From the churchyard turn left down the A10, here following the course of Ermine Street. Near the White Horse pub turn right into Marshall's Lane. Pass some modern houses, then Marshall's Farm and Marshall's (both Victorian), to descend into the valley by a winding holloway lane.
6 Cross The Bourne and go left by the footpath signposted 'Wadesmill' (the footpath is to the left, not the field track on the right). The path keeps alongside The Bourne almost into Wadesmill where it crosses to the other bank on a footbridge. It becomes a gravelled access lane and you reach the A10 road.
7 Turn right over the River Rib bridge. Turn left at the Post Office Stores of 1904, back into Ermine Street, Thundridge.
