Book excerpt: This guidebook provides 45 day walks in the Scottish Borders. Separated into six sections, these walks are divided between the north and south Cheviots, Tweed, Ettrick, Moffat and Manor hills and feature main centres including Wooler, Kelso, Melrose, Peebles and Moffat. The guide's seventh section outlines long distance routes, including a walk along the Border from Gretna to Berwick-on-Tweed. The Scottish Borders are rich in both history and geology. These walks explore many historical sites, from Iron Age forts on hillsides to bastles and towers dating from the Border Reivers era. The stunning and varied scenery is a result of complex geological processes; a visit to Dobb's Linn showcases preserved fossils, while the coastline at St Abbs Head features iconic folded rock formations which are home to a myriad of birds including guillemots. Each walk features 1:50,000 OS mapping, comprehensive route description and plenty of information about points of interest along the route. The walks are graded and can be easily customised with alternative start points, route variants and shortcuts. The guide's introduction offers plenty of practical information about how to get there and where to stay, while the appendices list useful contacts and tourist information centres.
