Chilterns based here and thoroughly paper map based too. None of this gps nonsense!
Your difficulty is getting out of hughenden valley itself – it’s all footpaths and I don’t know them. But get up to peterley corner farm on the A4128 turn right onto nags head lane then left on the BW through peterley wood. A bit of road through the back of prestwood then follow the little road down the valley onto rignall road -left then almost immediately right onto the BW by the little house. Climb up the other side and follow this along the ridge to duns more, straight over crossroads and then left fork at BW split. Follow along and look for a small gap in fence after about half a mile – take this BW down , awesome descent. Spits you out on a little road, turn right and follow to wendover.
At main road right then left and follow paths to church then right along road – follow round left at steep corner, turn right at junction, wendover woods is about a mile along this road on your right.
Can show you round a bit after the next couple of weekends, but I am slow fat and old!
Ps – yes we’re a friendly bunch at Summit!
