From the shore of Crummock Water, Rannerdale Beck can be followed to its source, gaining the ridge between Crag Hill and Wandope. The alternative western route follows Gasgale Gill up to its birthplace on Coledale Hause. From Braithwaite near Keswick at the opposite end of the ridge, Coledale Hause is also the first objective. From here a simple ascent turns Eel Crag to the west, although Wainwright listed more interesting alternatives on the eastern side of the crag.
