A few years ago I wrote up some 'wanderings' around West Penwith, taking in many of the major sites. My articles can be found here: https://heritageaction.wordpress.com/?s=penwith+wanderings as can my notes about various of the Cornish stone circles https://heritageaction.wordpress.com/?s=cornish+stone+circles

West Penwith is a place I know quite well now, and love dearly but I don't know the Bodmin area anywhere near as well. Feel free to shout with any questions though - a lot of people here are well versed in the Cornish sites.
