North Yorkshire Moors, it is actually signposted as a lorry park although you wouldn't have thought it, right on the top with splendid views. It is just off the A169 Pickering to Whitby road, just before you get to Sleights turn left signposted Grosmont (Not the first turning left, signposted Grosmont) 100 yds up there you'll find a compact gravel parking area on the left.
