Le GR® 3 est le premier sentier de Grande Randonnée officiel balisé en France. Randonner sur le GR® 3, c’est suivre le cours de la Loire, dernier fleuve sauvage d’Europe. La magie de la Loire ne se reflète pas uniquement dans son côté sauvage : c’est également un fleuve royal, qui a joué un rôle considérable dans l’Histoire de notre pays. Châteaux et forteresses, abbayes, ou encore petites cités de caractère ornent le rivage de celui que l’on surnomme depuis la Renaissance le fleuve des rois de France.

A tour round Ashridge Estate starting and finishing at the Bridgewater Monument. A visit through the Ivinghoe Beacon, Little Gaddesden, Berkhamsted Common and lastly Aldbury with plenty of great views, rolling hills and wildlife to keep you busy!
