The Helvellyn range runs broadly north-south for about 7 miles, remaining above 2,000 ft (600 m) throughout its length. Dollywaggon Pike is the southernmost fell of the ridge proper, with Nethermost Pike immediately to the north. There is a subsidiary top between Nethermost and Dollywaggon Pikes named High Crag (2,990 ft / 884 m). Due to the very limited depression between the two, most guidebooks follow Wainwright in counting High Crag as a part of Nethermost Pike. To the south of Dollywaggon Pike is the complex depression containing Grisedale Tarn, with Seat Sandal and Fairfield rising beyond.
