Recent surveys give the fell a height of 723 metres (2,372 feet), a significant increase to the 2,351 feet given by Alfred Wainwright in his Pictorial Guides to the Lakeland Fells. The fell is situated in Great Langdale in the midst of one of the most popular areas for walking in the district, surrounded by the much-loved Langdale fells of Harrison Stickle, Pike of Stickle, Loft Crag and Pavey Ark. Despite this, Thunacar Knott is often by-passed by walkers because of its uninspiring appearance, being just a slight rise on the moorland between Harrison Stickle and High Raise. Indeed, many people do not regard it as a separate fell, considering it just the outlying highest point of the spectacular Pavey Ark cliffs. Wainwright's comments on the fell are not positive, saying: ‘Thunacar Knott is completely unphotogenic…this uninspiring characteristic extends to the whole fell, which is quite deficient in interest.'
