Burnbank Fell marks the northwestern perimeter of the Lakeland Fells, its feet set on the boundary of the National Park. Beyond lie the valley of the River Marrom and the industrial towns of the coastal plain. Beyond the park boundary is the low double top of Mockerkin How (810 ft) standing above Mockerkin Tarn. A natural water body, the Tarn is known for its water lilies, is stocked with eel, pike and perch, and is associated with several local legends, including that of a sunken town.
