Start on the public path at the north-west corner of the visitor-centre car park on Monument Drive, beside the Bridgewater Monument. Follow Duncombe Terrace through Ashridge Woods to Clipper Down, then retrace the same route. Allow about two hours with stops.
Cross the green and join the main terrace path. It passes a wooden bridge above an old drovers' hollow, the Moneybury Hill burial mound and the replica shooting lodge. Further north, woodland openings give views towards Pitstone Hill and Aldbury Nowers. Continue to the Clipperdown Cottage junction, keeping outside the private cottage grounds, and turn back. The return has the same landmarks in reverse, making it straightforward to shorten the walk.
The track is generally broad, with gentle gradients and a compacted surface. Expect uneven patches, leaf litter and possible puddles; the wooden bridge can be slippery. Share the route considerately with cyclists and horse riders. Give deer space, especially during the autumn rut, and keep dogs on a lead around wildlife.
Parking is free in the designated visitor-centre spaces. Since August 2026, parking on Monument Drive's north verge is prohibited. Follow signs, choose daylight and check current access notices. Toilets and the Monument Cafe are beside the visitor centre; opening times vary.
