The Cairngorm mountains are located in the Eastern Highlands of Scotland and collectively form the highest and most extensive range in Britain. The main plateau (northern corries area) is formed from a large granite intrusion (pluton) and is incised by deep glacial troughs, corries, straths and glens.
The Lakeland fells are home to England’s highest and most dramatic mountain tops. The landscape is diverse but typified by craggy peaks (central/southern fells), upland tarns, and picturesque ribbon lakes. Overall the area contains 214 fells, 16 lakes (or ‘waters’) and in excess of 50 tarns.
The High Peak (or Dark Peak) of the Peak District is characterised by its peat covered gritstone plateaux. In contrast to the rolling hills of White Peak, the lesser frequented northern moorlands of Kinder Scout, Bleaklow and Black Hill can provide some difficult walking conditions and navigation.
The Shropshire Hills are a popular and scenic (but lesser known in hillwalking terms) area of geologically diverse hills, scarps and valleys. They are situated in the Anglo-Welsh borders and mark the transition to the Welsh uplands and mountains which lay on the other side of the border.
The Snowdonia mountains are an exciting and geologically diverse area located in north-west Wales. These ancient rocks have been heavily affected by periods of volcanic and glacial activity and offer one of the best examples of a true mountain landscape in the British Isles.
The Yorkshire Dales offer a classic limestone landscape that lays claim to the finest collection of Karst (solutional erosion) features in Britain. Areas around Malham and Ingleborough are particularly notable for their extensive limestone pavements, caves/pot holes and shake holes.
