The A-Z Adventure series features the accuracy and quality of OS Explorer mapping in a convenient book, complete with index. The A-Z Adventure series is an innovative concept that utilises Ordnance Survey Explorer mapping in a book, therefore eliminating the need to fold and re-fold a large sheet map to the desired area. OS Explorer is Ordnance Survey's most detailed mapping at a scale of 1:25 000, showing public rights of way, open access land, national parks, tourist information, car parks, public houses and camping and caravan sites. Unlike the original OS sheets, this A-Z Adventure Atlas includes a comprehensive index to towns, villages, hamlets and locations, natural features, nature reserves, car parks and youth hostels, making it easy to find the required location quickly. Each index entry has a page reference and a six figure National Grid Reference. At a book size of 240mm x 134mm it is the same size as a standard OS Explorer map when closed.
