Walks in and around the town: there are interesting alleyways, footpaths and open spaces to explore (see the Town Guide for a town centre map). If you'd like to follow a structured walk, try the blue plaque trail or pop into the White Horse Bookshop on the High Street to pick up local historian David Chandler's book 'Place Names of Marlborough' which lists eight walks around the town together with maps - from just over a mile exploring alleyways to 2 hour walks incorporating town, villages and countryside. The book shop also has a variety of other local maps and books, such as walks incorporating coffee shops and pubs. For history buffs, you might be interested in the Marlborough Tank Island War Walk, about two miles around the town, produced by the Kennet Valley at War Trust and available for download.
