The most popular Blea Tarn is without doubt the one in the Little Langdales, but this Blea Tarn is in Eskdale and I referred to it in my 1-9-19 image. This is from the same walk - an 8 minute exposure with a 15 stop filter - just playing :-)
So still, so beautiful. I've been to Eskdale but not to Blea Tarn. However my husband says he did a night exercise there and remembers walking right into the tarn in the dark!
