This is a lovely waterside walk to the delightful Watendlath Tarn near Derwent Water, Keswick. The walk starts at the Suprise Hill car park towards the southern end of the lake. This splendid viewpoint looks out over Derwent Water, Keswick, and beyond to Bassenthwaite Lake. You then follow woodland trails through Ashness Wood to Watendlath Beck where you pick up a super waterside trail which leads to the tarn. The pretty hamlet of Watendlath has an old packhorse bridge, and a National Trust tea-room, where you can sit outside and enjoy the wonderful views.
An alternative route is to walk up to the tarn from nearby Rosthwaite. It is situated about a mile south west of the tarn, with a good track leading directly up to Watendlath. See the video below for details on this route.
If you have time you could extend your walk by visiting the beautiful Lodore Falls.
