No prior permission required. Parking & changing as for Hillocks Mine. From barn take public footpath NE into field containing obvious overgrown mounds. Large adjustable spanner needed to undo & secure lids. (Emergency spanners kept at the pub in Monyash must be returned same day). Take precautions against stock falling into shafts left open during descent. Beware polluted water and bad air - this system is notorious for both, and trips may have to be curtailed. Heed any warning notices posted. All visitors are requested to fill in pollution survey book on way out, even if no pollution encountered.
Crimbo Swallow and Crimbo Pipe inlet are dangerous except in dry weather. Co2 build-up can occur in the lower parts of the mine.
