Smardale Gill is located in Cumbria, England. It is a small steep valley connecting the village of Smardale and the valley of the River Eden with the eastern edge of the valley of the River Lune. It is a National Nature Reserve and also a Site of Special Scientific Interest, managed by Cumbrie Wildlife Trust.
