Tewet Tarn and its surroundings are just so peaceful and a real joy to visit. The tarn, which is found found in a wonderful location at the northern end of St John's in the Vale is very easy to reach, yet still offers the feeling of getting away from it all. If the tarn is the sole aim of your outing, simply find a roadside space between Burns Farm and Naddle Bridge and within fifteen minutes you're there. Alternatively it can be included in a much longer walk, perhaps including the well known Castlerigg Stone Circle, St John's in the Vale Church and for the more energetic, an ascent of High Rigg. All of which can be included in the same half day walk. (see the list of walks at the bottom of this page).
Although not immediately apparent the tarn has a dam of sorts at the northern end, no doubt deserving credit for the tarn never drying out, even during prolonged spells of dry weather. In contrast to the footpath side of the tarn, the south and west edges are bordered by marshy ground, making access to the waters edge quite difficult along those sides.
The tarn is watched over by the mighty Blencathra, who's reflection is often mirrored in the tarn, making it more lovely than it already is. Some sources say that perhaps the tarn is named after the Peewits which seem to abound in this area, and more often than not put on a display of acrobatics as you walk past.
