Turner conveys the breathtaking grandeur and beauty of Llanberis Lake and the highest peaks of the Welsh mountains in this work, which is based on drawings he made in 1799. Watercolour washes suggest the misty atmosphere of the mountain range, while the detailed foreground is emphasised with touches of body-colour. The two men fishing watched by a mother and child suggest the awesome scale of the scene. This highly finished view was painted to be engraved for the series of plates, 'Picturesque Views in England and Wales', commissioned by the publisher Charles Heath. The first print appeared in 1826, but the venture failed commercially.
