Hen Hole - Valley close to England/Scotland border
Put this together with some clips I recorded while there - long hike to get there but incredible once there.
"On the north-west side of Cheviot there is a deep chasm called the Hen Hole, in which there is frequently to be seen a snow egg at midsummer. There is a tradition, that a party of hunters, when chasing a roe upon cheviot, were wiled by the fairies into the Hen Hole, and could never again find their way out."
