This guidebook describes walking and mountain-biking routes in Scotland's southern highland glens, the Trossachs - the Queen Elizabeth Forest Park, South Tayside and Lochearnhead, from Callander to Comrie and Crieff to the Ochils. One of a popular series of 9 guidebooks for walkers and mountain-bikers, using paths and tracks amid superb scenery in Scotland's wild glens. The aim of this series is to provide the mountain-biker and walker with information on an intended route so they know something of what to expect. One of the problems is that OS maps give no indication as to whether an 'other road' is metalled, a path or a forest fire break, or anything inbetween. Many bridges shown on OS maps do not exist. Rivers are difficult to judge in size from the map, and a building may be anything from a pile of stones to a maintained bothy. All is revealed without removing the sense of adventure and exploration. Gradient profiles help to assess how strenuous a route is, and each hand-drawn page contains a wealth of information. The object is to save wasted leisure time and enable the armchair explorer to plan ahead or relive experiences.
