Length: 15¾ km (9.8 miles) to Shoreham, or 19 km (11.8 miles) to Otford. Toughness: 4 or 5/10
10:12 Dover train from Victoria (Denmark Hill 10:22, Bromley South 10:36, etc), arriving Farningham Road at 10:51.
Trains back from Shoreham are half-hourly at xx:08 & xx:38 and go to Blackfriars (slowly). If you continue to Otford you can catch these trains three minutes earlier, but there are faster services at xx:13 (non-stop to London Bridge, then Waterloo East & Charing Cross) and xx:55 to Victoria.
Farningham Road is on a different line to the other stations and there's some detailed ticket advice in the walk document (see Transport), but in practice a return to either Farningham Road or Otford (which are the same fare) would probably be accepted.
This walk in the Darent valley had a Saturday outing a few months ago but the post-walk report revealed that large chunks of the author's route were discarded in favour of some ‘freestyling’, so even if you did it then you might find that following the published route is a new experience. I've given it this repeat outing because the afternoon leg goes past Castle Farm; its extensive lavender fields should be in full bloom and you can sample or buy their products in its farm shop.
There are plenty of refreshment places along the walk route. You might find it hard to resist the temptation of an early lunch stop as the route goes right through the riverside beer garden of the Lion Hotel. There's also a designated picnic area across the river, just beyond the curious structure spanning it. The alternative is to carry on for another half hour to Eynsford, which also has a riverside pub (the Plough Inn) plus others on its High Street.
If you want something to supplement the lavender ice cream at Castle Farm there are a couple of tearooms in Shoreham, and tea'n'cake might also be on offer at the church. A ten-mile walk might be more than enough for most of us on a Sunday, but if you need to work off all those extra calories you can continue for another hour or so to the next station down the line, Otford.
NB. There will probably be some noisy motocross activity in the first part of the walk at Canada Heights (a drawback of posting this walk on a Sunday). This might be quite fun to watch for a few minutes but if you want to avoid it you could take the train an hour later and do the shorter start (option a′); you'd only be 15 minutes behind the main group and might be able to track them down in one of the lunch pubs.
You'll need to bring the directions from the L=swc.291.a page. If you're printing them from this page you can save a few sheets of paper by first clicking ‘Main’ on the Walk Options heading line.
