Grasmoor is distinguished by its steep western flank, dropping dramatically to Crummock Water. This face is however not suitable for rock climbers as there is little clean rock, although Alfred Wainwright describes a challenging route up the face in his Pictorial Guides to the Lakeland Fells. To the east the fell is linked to others by Crag Hill and Coledale Hause. Grasmoor is also home to the most extensive scree slopes in the North Western Fells.
