Corstorphine Hill is an L-shaped wooded ridge which has been designated a Regionally Important Geological Site due to the variety and accessibility of interesting rock formations found there. It is also a nature reserve which is home to a large colony of badgers and a wide variety of birds, including woodpeckers and tawny owls. At its summit there is a tower dedicated to Sir Walter Scott which is open to the public and offers some outstanding views of the city of Edinburgh. There is also a beautiful walled garden and some traces of a Bronze Age settlement including the mysterious cup shaped markings, which it is speculated may have served some religious purpose.
