OS grid ref:- NY 349 079
Alcock Tarn is situated on a shelf on the western flank of Heron Crag, overlooking Grasmere. It was originally a small natural tarn known as Butter Crags Tarn until it was enlarged in Victorian times by Mr Alcock of Hollins in Grasmere who stocked the tarn with brown trout.


Superb views are to be had from the tarn of Grasmere to the west, Lake Windermere to the south, while Coniston is clearly visible to the south west. On a clear day Blackpool Tower can be discerned in the distance.
