#3: Chalfont & Latimer to Chorleywood
Both Chalfont & Latimer and Chorleywood stations have good train frequencies and the Oyster card can be use, so they make good places to walk from.
This walk goes down into the Chess Valley and heads back towards Chesham before going up to the other side of the valley to visit the villages of Flaunden and Sarratt and going back across the valley to Chorleywood. It is 19km in all, but there are plenty of options for shortening the walk if this is too long.
