(S/E) Come out of Colliers Wood car park on to the road and turn right. When you reach the main road, follow this until you reach a junction and the main road curves off to the left.
(1) Turn right on to the road that meets from the right and then almost immediately left on to a track. The reservoir will now be on your left and a house is to your right as you go through the gateposts. Continuing following the track until it carries straight on and a smaller track joins from the right.
(2) Follow the track down to the left as it begins to wind through a more heavily wooded area. Continuing following this track through the woods with the reservoir on your left, ignoring any smaller tracks that join from the left or right. The track eventually leaves the reservoir and there are wooded areas on the left with open fields through the hedges to the right. The track eventually curves left around point (6) and you will come to a stream directly ahead of you.
(3) Turn right and continue to follow the track, with this steam on your left, until you meet the water in front of you, with a concrete bridge. Do not go through the water or over the bridge, instead turn right through the trees which emerge out into an open, concreted area. Continue walking straight on the stoney path. Keep following this track straight as it goes uphill with a hedge on your left and open fields to the right. At the top of the hill, there is a bench which is ideal for a lookout or picnic spot. Continue to follow the track until you eventually pass America Farm on your right and over the M1 motorway bridge.
(4) Shortly after crossing the M1, another track joins from the right. Take this track and turn right, with woods on your left and an open field to your right. Continue to follow the track past the houses on the left, over the horse style and down until a track meets from the left. Bear right around the corner and go under the M1 motorway. Continue following this track as you walk along 'Felley Tops' which has great views. You can see the Church Spire of Underwood in the distance. Woods will be on your left with open downward sloping fields to the right.
(5) When the track curves round to the right and begins to descend downhill, with a tree either side, continue walking straight with the woods on your left around the edge of the open field. When you reach the hedge line between the two fields, turn right and continue to follow the edge of the field with the hedge line to your left. You will eventually meet trees at the bottom, which have a faint path through, for you to reach the track that you have already come down.
(6) After passing through the trees and rejoining the track, turn left and follow this back along the reservoir to the main road and back to Colliers Wood Car Park (S/E).
