A flexible friend for everyone!
This Guide has a unique structure: at each of ten locations in the heart of the Chilterns you can choose a short, medium or longer walk AND combine them into figure of 8 to give 6 choices of walk between 2-13 miles.; also, each walk description is on the same or facing page as its accompanying OS large scale map extract, with a cross referenced checkpoint every 15 minutes walking time to help avoid getting lost. You are also able, free of charge, to download the GPX routes onto your smartphone/GPS. The result is that it is very flexible in use e.g. you can park your car before deciding how far you want to walk, depending on current fitness, time available and weather conditions.
For experienced map readers possessing the Chiltern OS Explorer maps, there are an extra 14 locations with 42 extra walk choices between 3 and 12 miles( also with free downloadable GPX files)
