The guide surveys the region's physical geography and geology, its flora, and a concise historical overview before turning to prehistoric and medieval antiquities and the distinctive parish churches and calvaries. It discusses local religious festivals called pardons and the iconography found in church sculpture, and it outlines practical advice for travelers. The second half offers alphabetical, place-by-place descriptions of towns, coastlines, and curiosities, supplemented by photographs, illustrations, and maps, with attention to local costume, customs, and travel logistics.
