Length: 20.5 km (12.7 miles) 6/10
I've picked this walk because it has been recommended as a promising area for bluebells, as well as being an excellent walk from memory: a mixture of woods and open views, not too far away, and passing interesting places including Churchill's house at Chartwell.
Travel: 0950 from Victoria arriving at Hurst Green at 1034 or 1007 from London Bridge arriving 1038.
Returning from Penshurst station there are two trains an hour to Tonbridge where you change for Charing Cross, and two to Redhill where you change for London Bridge. A return to Penshurst should work; if returning via Tonbridge make sure your ticket covers that.
Lunch: the original lunch pub on this walk has closed and the best non-picnic option looks like the NT cafe at Chartwell (tel 01732 863087), 7.5 km from the start of the walk, which serves good food from noon to 4 pm. There is a possible late pub stop at in Ide Hill, 13 km from the start of the walk - the Cock Inn (tel 01732 750310).
Tea: the Little Brown Jug Chiddingstone Causeway, Tonbridge, TN11 8JJ (01892 870318). I recall this pub having erratic opening hours but apparently it is now open noon-11pm Mon-Sat and offers tea and coffee.
Short walk option: The Book 2 description and walk directions include a 9 km route, following the main walk to Limpsfield Chart and finishing at Oxted. If you do this and start later, you could lunch at the Carpenters Arms (tel 01883 722209), 4 km from the start of the walk. There doesn't appear to be a GPX track for this route but if you followed the final section of walk SWC 63 from Limpsfield Chart you wouldn't go far wrong. You'll only need a return to Hurst Green if you do this walk. There is a plethora of other options on the walk's web page with different starts and finishes.
