There is a tremendous proliferation of broken granite outcrops at the far northern spur of Standon Hill. Whilst Crossing and Hemery make brief references to the area with the former adding the alternative name of Outer Standon, neither author really captures the essence of the location. Set high above the confluence of Rattlebrook with River Tavy and south of the latter, Knoll is essentially a ruined tor, with several low embedded outcrops overlooking a cascade of granite, some of which have been contorted into weird shapes that captivate the onlooker.
Views are exhilarating especially to the north up the Rattlebrook Valley where the ruin of Bleak House is just visible on the horizon. Elsewhere there is thrilling vista of Tavy Cleave and the hillside opposite which is similarly smothered in broken rocks.
Rarely visited Knoll is an unforgettable place and is best reached from the south via the Standon Hill hut circles a remarkably well-preserved settlement that commands superb views of the five Tavy Cleave Tors to the north and west.
