The obvious ones are the Hurlers and Trethevy Quoit. The Trippet Stones and King Arthur's Hall can make good pictures too. Mr Hamhead (as ever) can give a definitive answer on this one - he knows the moor very well.

It really does depend on the weather in that part of the country though. Mist can move in very quickly with very little warning.

I'll be down that way myself on the 13th this month - but a bit further down, in West Penwith.
