Travel Book of the Week As a wannabe walker, I'm much taken with the Discovery Walking guides new Walk! UK series which covers all the major walking destinations from the Lake District to Exmoor. Walk! The Brecon Beacons, GBP12.99 by Bob Greaves, is a handsomely produced book of 160 pages in full colour with Ordnance Survey mapping and a spiral binding. Each itinerary includes a route summary, ratings for effort, time, distance, ascents/descents, refreshments and vertigo risk, a fully detailed walk description, global positioning waypoints along the route for pin-point navigational accuracy and a full-colour 1:40,000 scale map of the route. There is a good choice of walks for all abilities. Frank Barrett --The Mail on Sunday March 5 2006
