These walks will cover the whole of the Greensand Way, using trains to get to the start and from the finish points. It is possible to do the entire route in day walks starting from central London, although there are a couple of very long sections owing to the absence of convenient stations.
The route is moderately well way-marked - in Surrey with small Greensand Way plates added to footpath signs and with standard waymark arrows with 'GW' in the middle; in Kent with an oast house in the middle of a circle. However, waymarks and signposts are sometimes missing or overgrown, or just placed where they are not obvious, and checking the route on your phone regularly is advisable.
The first section is a pleasant mix of woods and heathland, with a number of fairly steep ascents and descents. 'Sand' is much in evidence, but it definitely is not green! The views from Gibbet Hill would be spectacular on a nice day. Sadly quite a bit is on roads and tracks, and although these are quiet you may be disturbed by the noise and fumes of scambling bikes.
Trains to Haslemere are reasonably frequent, but those from Witley on a Sunday are only hourly at the time of writing, so it may pay to adjust your walking speed suitably!
