Cheap advance train ticekts for walks from London

[Victor8181]

I've used a few of these with my girlfriend, most recently Victoria to Seaford and then back from Eastbourne so we could do the Seven Sisters walk. About £7 2 months in advance with Southern trains.

Anyone know of any other good walks you can do from London and get cheap advance train ticekts for?

Blimey, that request sure is a bit esoteric.

Good luck with it, anyways.
