This guidebook describes 30 circular walks in Scotland's Pentland Hills, a range of low summits which extends between Edinburgh and Biggar in South Lanarkshire. Ranging from 3 to 27km (2-17 miles), there is something to suit all abilities from the novice to the experienced hill-walker, with each route showcasing a different aspect of the area's unique character. Step-by-step route description is accompanied by 1:50,000 OS mapping and a wealth of interesting information on the region's rich natural and cultural heritage: its geology, history, wildlife and connections with literary greats such as Robert Louis Stevenson and Sir Walter Scott. Local place names are explained, local folklore explored and there is a helpful glossary of dialect terms. The Pentland Hills can be enjoyed in all seasons. Although the highest summit, Scald Law, stands at 579m, stunning vistas belie their modest elevation: this is a region of grass and heather-clad slopes which rise above picturesque valleys hiding streams and reservoirs. Walking in the Pentland Hills is an ideal companion to discovering great walking on Scotland's most accessible hills.
