Five nature reserves, deep woodland, and a Roman road
7 miles (11.3 km)
This walk takes in five nature reserves, passes the site of an ancient moated encampment, and ends with a two-mile stretch along Ermine Street, a former Roman road which passes through deep and shady woodland. In between are rolling hills with open views.
There is one short part where you pass under the A10 and back, but either side there are pretty paths and you soon forget the road. Between points 15 and 16 we saw a "Caution Bull in field" sign on the footpath gate, but we didn't see any bulls. There is a diversion along the road if you are concerned.

Note: When we did this walk in July 2018 and in March 2019 there were Caution - Bull in field signs at both ends of this path, although we didn't encounter any bulls on either of our visits. I can never understand why farmers are allowed to let dangerous animals loose along a public right of way. If there are bulls in the field and you feel unsafe we suggest you retrace your steps to point 14 and turn right following the pavement alongside Hertford Road (B1197) until you meet Hailey Lane on your right. Turn right on Hailey Lane walking along the grass verge until you pick up the walk again at point 16 below. The alternative route is shown in yellow on the maps above and below.16: At Hailey Lane turn right and then first left taking Hertford Heath Bridleway 14 that goes through the grounds of Haileybury College. The path cuts through the college grounds in a NW direction until it reaches a path leaving the college grounds at the southern edge of woodland.

If you want you could take the track on your right heading into another part of Hertford Heath and follow it round to point 20 below. See yellow detour on the maps above and below.
