Train: Take the 9:13 AM Aylesbury train from London Marylebone to Saunderton, arriving at 9:55. Late risers who prefer a shorter walk can take the 10:43 AM Banbury train from London Marylebone to Princes Risborough, arriving at 11:27 and just do Book 1 Walk 52 in its entirety. If all goes smoothly you should rendez-vous with the Saunderton starters at the Plough – probably arriving about 20 minutes before the earlier starters. Return trains from Wendover are at 23 and 53 minutes past the hour until 22:23. Buy a day return to Aylesbury.
Distance: 14ish miles or 22.5ish km for those more metrically minded and 8.4 miles/13.5 km for the later/shorter route.
Difficulty: 7 out of 10 (6 out of 10 for the shorter option)
As something a bit different in the Chilterns, I thought this combination of two trusted favorites would make an enjoyable extended foray through the Chiltern hills and woods. We will set off doing SWC 10 in reverse from Saunderton to Lower Cadsden for lunch. After lunch, we will swap over to the instructions for Book 1 Walk 52 to complete our journey from Lower Cadsden to Wendover. Both morning and afternoon routes pass through beech woods which should hopefully be tinting nicely. The walk also includes a couple of nice panoramic views from which to survey the surrounding autumnal countryside. More information and the instructions can be found here and here. Don't forget both sets of instructions and it will also be useful to print the map for the morning section!
Lunch will be at the Plough in Lower Cadsden (01844 343 302), a popular pub. If numbers are very large, some could also have an early lunch at the Pink & Lily in Parslows Hillock. Recommended tea places in Wendover include Rumsey's Chocolaterie open until 18:00 (on the High Street about 5 minutes from the station) and the Shoulder of Mutton Pub (next to the station).
