Think on this.
Most of the caves under Leck and Casterton Fells are part of the Three Counties System. A permit is required for the entrances on these fells. Yet easy and unpermitted access can be gained if you access this same system via Link, Pip, Boundary, Mistral, Bull Pot, Ireby, Large or Rift.
You can park at Bull Pot Farm, get kitted up in full caving gear, walk over the CRoW open access land, walk past Lancaster Hole (but you can't go down it), continue to the entrance of Link Pot, go caving, end up underneath the entrance shaft of Lancaster Hole (but you can't go up it) and exit via Boundary Pot and walk back to the car over Casterton Fell. This doesn't make sense.
