The little carparky thing that's closest is at about SX662878, tho it doesn't appear on the Explorer.
The roads to get to it are pretty narrow & twisty & turny just about all the way from the main road - so it takes a while. The walk from there is easy & about 10(-15) mins, gently uphill then gently downhill. fine for you but prob a bit far for Mikki, I'd guess - 'cept mebbe if you REALLY took yer time.
