“Ivinghoe Beacon is a prominent hill and landmark in the Chiltern Hills, standing 233m (757ft) above sea level. It is situated close to the village of Ivinghoe in Buckinghamshire, the Ashridge Estate, and the villages of Aldbury and Little Gaddesden in Hertfordshire and is managed and owned by the National Trust. Ivinghoe Beacon lies between the towns of Dunstable in Bedfordshire, and Berkhamsted and Tring in Hertfordshire. It is the starting point of the Icknield Way to the east, and the Ridgeway long-distance path to the west.”
