Train down (or drive) from Waterloo to Godalming and then explore Thursley and Hankley Commons, then up to the Devil’s Punch Bowl, Gibbet Hill and back via Witley/Milford. Alternatively, down to Haslemere and do a big loop via the Devil’s Punch Bowl, Golden Valley, Ludshott Common and loop round Liphook via the commons and then climb Blackdown and back to Haslemere. I’ve probably got some PDF route maps if you want them. Mostly bridleways but some good riding, which I miss since moving away 🙁
