There are five small lakes or tarns, called the East Tarns, grouped together on the eastern part of the plateau just to the north of the summit of Tarn Rigg Hill. The West Tarn, meanwhile, lies at the north-western end of the summit plateau at , and is difficult to find on the almost flat top because it nestles in a slight hollow, even though it can be seen from the trig point. It may be located from the latter by following the western rim of the plateau, overlooking Sedbergh, until two cairns point the way to the tarn.
