Merlin's Mine, Top Entrance
Two entrances, of which the lower (adit) entrance is most used. High above Carlswark's Eyam Dale Shaft, but closer to the road junction.
No known access restrictions. Obvious parking spots close to base of crags and in lay-bys in the dale and next to electricity sub-station at foot of Eyam Dale. DO NOT BLOCK the sub-station entrance. Take care, as area is notorious for thefts from parked vehicles.
