This is the largest and said to be the prettiest of all the tarns on Claife Heights, an upland area of the Lake District close to Windermere and one of Wainwright’s outlying fells. It was donated to National Trust by Beatrix Potter who stocked it with fish and water lilies. It is also surrounded by rhododendron bushes and a small dam bridges the outflow.
Moss Eccless Tarn is very popular with walkers and for fishing for brown trout by tickets from local outlets. It can be reached by following a track from Near Sawrey (between Hawkshead and Windermere). The tarn is part of the Claife Tarns and Mires Site of Special Scientific Interest.
