Families: "Get 'em away from the Play Station". Get quality time together. Study nature. They'll remember one day out in the country more than 100 days with the latest gizmo.
Churches: Support a major Christian charity. A great get-to-know-you opportunity. Come to one of the services in Berkhamsted before you walk or start the 6 mile walk before 2pm.
City types: Get away from the noise and stress and get exercise in stunning countryside nearby. Easy to follow route. Come with your friends.
Schools: Develop countryside skills, prepare for D of E. A low risk, well signposted circular walk. Encourage commitment to less well off children.
Walkers: Sample the delights of the Chilterns and National Trust Estate without the effort of planning your own route.
