Length: 17.7 km (11 miles). Toughness: 3~4/10
Buy a day return to Pluckley and take the 10:04 Dover train from Charing Cross (Waterloo East 10:07, London Bridge 10:13, Sevenoaks 10:37, etc), arriving Headcorn at 11:09. Nip down the station approach road to the bus stop on this side of the main road for the Arriva 12 bus towards Maidstone at 11:19 (or perhaps share a taxi if it doesn't show up). After an 11-minute journey alight at the King's Head pub in Sutton Valence for the start of the walk.
If you'd prefer to avoid the bus connection you could instead take the 09:55 / 10:55 Ashford Int'l train from Victoria and do the walk's alternative start from Harrietsham (arr 11:13 / 12:13). The earlier train would get you to the lunch pub about 40 minutes before the main group; the later one about 20 minutes after. See the walk notes for ticket advice on this route.
Trains back from Pluckley to Charing Cross are hourly at xx:37. You could take a train in the other direction at xx:46 and change at Ashford for a High-Speed train to St Pancras, but you'd need to buy a fairly expensive ‘Plus High Speed’ supplement for this route.
This is a pleasant section of the Greensand Way through the ‘Garden of England’, with plenty of orchards and some fine old churches along the way (though not many pubs). The only convenient lunch place is the attractive Pepper Box Inn, which the Sutton Valence starters should reach at around 12:45–1pm. It has plenty of outdoor seating but as usual book a table if you want to be sure of Sunday lunch.
A mid-afternoon tea stop looks unlikely as the George in Egerton is reportedly closed. The choice for refreshment is between diverting to the Rose & Crown in Mundy Bois (open all day) or carrying on to Pluckley village for the Black Horse (open to 6pm). In both cases allow plenty of time to reach Pluckley station as the Dering Arms closes early on Sundays and there's nothing else nearby.
