Alcock Tarn Walk

The Alcock Tarn trail is an amazing route in the Lake District due to its relatively short overall length and breathtakingly scenic views. From the top of this trail, you will experience views of the charming mountaintop lake, as well as the surrounding landscape that includes numerous fells and the lakes of Grasmere and Rydal Water in the valley below. This is one of the top walks in the Grasmere area and it should absolutely be near the top of your list.
