The Greensand Way is long distance walk of 111 miles in southeast England, from Haslemere in Surrey to Hamstreet in Kent. It follows the Greensand Ridge along the Surrey Hills and Chart Hills. The route is mostly rural, passing through woods, and alongside fruit orchards and hop farms in Kent and links with the Stour Valley Walk near Pluckley in Kent. The trail was opened on 15 June 1980.

The trail is jointly managed by Surrey and Kent Councils who fully updated it in 2012 (route, waymarking, online guide). Note that the waymarks alone are not sufficient to follow the trail - a OS map, or the online guide with maps, is required. OS Explorer Maps 125, 133, 136, 137, 145, 146, 147, 148

An updated guide with maps and walk directions is available online from the Kent and Surrey Council websites. Public transport information, OS maps and GPS data is available online from the Saturday Walkers website. The original guidebook is out of print.

On Ordnance Survey Explorer map 145, a spur - also labelled Greensand Way - is shown from Thursley toFarnham. This is not part of the path.

Much of the land is designated an Area of Outstanding Natural Beauty. The stretch from Hindhead to Leith Hill has formed part of the Surrey Hills AONB since 1958. The Sevenoaks Ridge, from the Surrey-Kent border to Borough Green, is included in the Kent Downs AONB.
