Great Asby Scar is an area of high ground lying between the villages of Orton and Great Asby famous for its limestone pavement and is a National Nature Reserve because of this and the plant species that hide in it.
The highest point of the Scar is called The Knott at 412m (1352 feet) with Castle Folds, an old fortified settlement, found high on the limestone fells.
Great Asby Scar is another great little hill which can be easily summited. You can walk up from Orton for the full experience, or park besides the Orton to Appleby road to get a bit of a head start. There are a series of paths leading through the wide area of limestone pavement. This is a large area of limestone pavement which is a bare area of rock left behind after the last glaciation. Limestone is slightly soluble in rain water leading to a pattern of blocks known as clints, separated by cracks known as grikes. Be warned - this type of pavement is difficult to walk on, especially when wet, so you are better off sticking to defined paths.
