I went up that way a couple of years back Boxelder and stuggled finding the way up to Whitemoss from Miterdale. I got to the old outdoor centre and then the track just disappeared and it became a slog through the bogs until I found the good trail coming up from Boot to the stone circles.
I was heading the other way – back to Boot – so no idea what it is like heading to Burnmoor Tarn.
I don’t know if the trail up Tongue Moor that passes above the tarn from Miterdale is any better? Or the one up from Boot along Whillan Beck?
I just remember that slog… it was an absolute nightmare! Which is a shame as the ride up Miterdale itself had been rather pleasant.
