This guidebook - which includes both a guide to the route and a separate OS map booklet - describes the Ridgeway National Trail, an 87 mile (139km) route through southern England from Avebury in Wiltshire to Ivinghoe Beacon in Buckinghamshire. Typically walked in 6 or 8 days, this is a low-level waymarked route suitable for all abilities and for year round walking. The guidebook details the trail in both directions, west to east and east to west (the main description is west to east). Step-by-step route descriptions are accompanied by 1:100,000 OS mapping and a separate OS 1:25,000 map booklet showing the entire route is included. Packed with details on points of interest and a trek planner giving at-a-glance information about facilities, public transport and accommodation available along the way, this book is an indispensable guide to walking this national trail. Following a ridge of chalk hills through the Chiltern Hills AONB and North Wessex Downs AONB, the Ridgeway takes walkers through five counties and five thousand years of history. It offers a scenic and fascinating journey through our ancient and more recent past, visiting the UNESCO World Heritage Site of Avebury's Neolithic stone circle and the famous Uffington White Horse, and includes excursions to picturesque villages, thatched cottages and cosy pubs.
