The Vanguard Way is a 66 mile (107km) footpath from south London to the south Coast - from East Croydon station to the Seaford cliffs & Newhaven station.
Not too long and not too short it takes a few days to walk it all.
This guide combines the text & information from Colin Saunders with 3,000 photos (at points along the route & of things to see) taken mostly by John Jefkins who also created this app.
You can download the text, offline maps and photos in 10 sections (each of about 12mb) using your own wifi before you set-off to view the whole route.
Whilst en-route, the app also allows you to view on-line maps that use location services to display the blue dot (to show where you are on your phones maps) - should you get lost.
More information about the Vanguard Way and its history can be found on the Vanguard Way website http://www.vanguardway.org.uk/.
This guidance has all been produced by voluntary effort from members of the Vanguard Way rambling club and this app is offered to you on that basis.
