The two summits of Craiglockhart Hill form a prominent landmark which has resulted from the fact that the igneous rock is more resistant to erosion than the surrounding sedimentary rock. The recent ice sheet in particular has helped to mould the present landscape. The igneous rock consists of lava flows and ash layers giving the appearance of bedding which dips towards the west. A short walk to the summit rewards you with breathtaking views of Edinburgh while the southern slopes offer recreation in the form of golf. The local nature reserve is frequently used by the community and has also achieved status as a Biological Site of Special Scientific Interest. The valley between East and West Craiglockhart is probably a glacial meltwater channel.
