The Shannon Valley covers the area in the triangle of lang between Athlone, Ballinasloe and Portumna and centres on the River Shannon, River Suck and Little Brosna River. The two-sided, folded guide and map combines artwork and text to introduce the main hertiage features such as Clonmacnoise and Clonfert but also invites the visitor to explore lesser known sites of historical and environmental interest. The map side is in full colour and depicts bogs, eskers, river floodplains and species of flowers and birds. It also marks places of heritage interest and includes angling locations, marinas and long-distance walking trails that traverse the area. The reverse side of the map contains fifteen pages of text, illustrated by seventeen pencil drawings, to provide information on natural history and heritage, including castles, Napoleonic fortifications and a wealth of ecclesiastical sites. Grid references are used for easy cross-reference between the text, illustrations and the map.
