1 Park your car at the finish and walk back to the A25, using the safe bridle track on the left-hand side of the road. Turn left to the bus stop, 40yds (37m) along the main road, and catch the number 32 bus to the start at Brockham Green. Get off the bus, walk across the village green to the Dukes Head, and turn right. After about 55yds (50m), bear left through a small white gate onto the Greensand Way, waymarked 'GW'. The narrow path leads you to a substantial footbridge over the River Mole; bear right here, onto a broad, tree- lined track. After 100yds (91m) look out for a heavily overgrown Second World War pill box nestling between the track and the river. There's a thoughtfully placed bench seat here too, and it's a very pleasant spot for a riverside picnic.
2 The track climbs gently to a three-way wooden signpost; keep straight on along the waymarked route towards Betchworth, then continue through St Michael's churchyard and up Wonham Lane, beside the Dolphin pub. Back on the walk, the Greensand Way sidles off to the left just beyond the Dolphin, and follows the edge of an open field as far as Sandy Lane. Turn left, follow the road over a low hill to the T-junction opposite Knowl Cottage, and turn right. After 25yds (23m) turn right again, up a narrow flight of rustic steps to a stile. Nip across, follow the field edge to another stile, then turn left onto a bridleway for 150yds (137m).
Now turn right over a 'GW' waymarked stile, and follow the Greensand Way to Dungates Lane. Turn right, and continue past Dungate's Farm to the edge of Reigate Heath golf course. They've been playing golf here since 1895, so it's only fair to give golfers priority. Cross the course with care, then climb the heather-clad slopes of the low hill towards the clubhouse and windmill.
3 Turn left onto the golf club drive; then, just past Golf Cottage, follow the Greensand Way down a grassy track on the right. Cross Flanchford Road and the golf course and keep Bracken House to your left as you follow the waymarked route up a woodland track. Pass Tile House and follow the path round to the Skimmington Castle pub. Turn left in front of the pub, then follow the waymarked route past the edge of the golf course and back to the car park at the beginning of the walk.
