Right on the Oxfordshire/Buckinghamshire border and in the heart of the Chilterns this walk climbs Chinnor Hill for fine views over the Vale of Aylesbury, before descending to Radnage with its 12th C Templar church and returning over Bledlow Ridge. There will be an opportunity to visit The Lyde Garden in Bledlow after the walk. Free entry but no dogs please. Information on The Lyde Garden  here .
