(S)From Chalfont and Latimer station, exit the car park and follow the main road to the left under the railway bridge. Take the next road on the left (Bedford Avenue) parallel to the railway line and then turn down Chenies Avenue on the right, and go ahead at the crossroads. At the end of Chenies Avenue, a path leads down through woodland, across a road and a field and the first view of the River Chess is seen on the right with the weir of the Great Water on the left. Follow the lane uphill to the right and then turn left along a narrow fenced path with a view looking down on the Great Water below, one of the better views of the walk.
(1)This is part of the Chess Valley (CV) route and, after skirting a field, the route enters woodland at a sign and goes down a narrow path where nettles may try to encroach in places. The route leads across a couple of fields and Blackwell Farm is reached. Follow the signs for the CV walk that passes between farm buildings. One section here can be very muddy after rainfall but on this occasion (May 2015) the ground was rock hard and cracked in places.
(2)Broadwater Bridge is a route junction for walkers and you leave the CV route here to take a path uphill through woodland to the right. Ignore the first option to branch right down Bunn's Lane but continue ahead along a narrow path with partially encroaching vegetation either side to reach a T of public bridleways. Turn right here along a woodland track that leads to a road, Green Lane. Next follows a section of road walking. Follow the road round to the left, and then left again at the next junction, then right uphill at the next fork with Chesham and Ley Hill's golf course appearing on the left as the road goes uphill.
(3)Turn right at the T junction and then take the public bridleway on the left. As the word bridleway suggests, you are more likely to encounter horse riders along here than walkers. The track offers wide expansive views of undulating landscape and farmland before it passes through woodland then opens out again to descend to Flaunden Bottom. The word "bottom" indicates a shallow valley and Flaunden is the name of the nearest village which is where this route heads next, following the road called Flaunden Hill which turns sharp right at the top of the hill as the village is reached with the church on the right.
(4)Turn left to pass the Green Dragon restaurant on the left and, go ahead at the crossroads and look out for a public footpath sign on the right for the Chiltern Way which is now followed as far as Sarratt with a mixture of field crossings, woodland, narrow country lanes and farmland. The church at Sarratt is a convenient place to stop for a break. The route rejoins the Chess Valley route by descending the grassy hill. There is some private land here but once the path emerges from woodland into the open, there is public access to the right with a footbridge across the chalk stream and a good view of it accordingly.
(5)For the concluding section of the walk, the CV route goes beyond New Road, passes through more woodland where it leads over a footbridge. In May 2015, the sloping field the other side of New Road was carpeted with mostly white flowers, presenting a picturesque scene. Before reaching the busy motorway - audible from here - take a track to the right up through woods which becomes an unsurfaced road which leads to Chorleywood with its cricket pitch and common, beyond which is Chorleywood tube station.(E)
