Different car park Goff. The one around the approx ref I've mentioned is a fraction nearer than the Batworthy Corner one (at SX662865ish) by Shovel Down rows, and it's a slightly easier walk.
I saw another site that mentioned that the walk from Batworthy crosses a 300yd wide bog that's 3 feet deep in inclement weather! Take a look out of the window...
I'll try Moth's car park, dependent upon weather signs, and leave Shovel Down for another time...
