In reply to SARS: Camped at Luckey Tor several times: beautiful, isolated, sheltered and offering some good climbing (and swimming in a warmer season).
If you park at Hound Tor, then follow a track through an open area used for horseriding and head for Holwell Tor you will find a really picturesque flat area alongside a stream. Perfect spot to set up camp and close enough to Hound Tor, Holwell Tor and Smallacombe Rocks.
You could set up camp by Hay Tor Lowman reasomably underdisturbed - I guess the thing to do is get packed up not too lomng after first light, then there would be no reason to complain.
