Very large place with deep inclines a long hike underground. Dont require caving gear except for helmet and wellies. We went in via the manway, then went along the bottom level for a while, before a large incline with machinery tempted us back up.
Lots of poking around before we went up another level to look at a tipper. I then solod up a slope to find a different way around before crossing over the surface and dropping back in again to meet Rob and Byron at the bottom before doing iit again.
