Set in the high mountains of the northern fells, Carlside Tarn barely gets a second glance from anyone passing this way. And the first glance usually causes an "I didn't expect to see a tarn up here" moment. The tarn, which sits in a grassy col between Carl Side and Skiddaw is, and I'm sad to say this, distinctly lacking in beauty. Even though the tarn is little more than a shallow puddle, it still deserves recognition, simply for the fact that it's one of only a handful found in the whole of the Northern Fells.
As an aside note: The tarn is found next to what is arguably the finest route to one of Lakeland's finest mountains; the Ullock Pike / Longside ridge. Skiddaw must surely attain one of the highest number of visitors of any fell in the Lake District, but only a fraction of those who reach the summit actually reach it by this fantastic route; which just happens to pass by the tarn in question.
