Take the B6465 south off the A623 past the Rolley Low, Castlegate and Hay Dale Barrows. You will see a sign for Monsal Head viewing area on the right. Turn here and follow the minor road north through the gorge.
The drive through Monsal Head gorge was wonderful.
Sheer cliffs (bit like Cheddar) and tall trees with the sunlight falling through the gaps in the canopy.
Unfortunately the Barrow in question was on top of one of these cliffs and there was no way up. The only way of access (unless you are Spider-Man) would have to be an approach from the west – something I didn’t have time for.
It is of no real surprise that E.H. have nothing to say on the matter.
