This grand circuit follows the open ridges of the more remote Western Pentlands. There are superb views throughout, over the main Pentlands range, over Edinburgh and the Forth Bridges, and into the Borders. The return follows the Thieves' Road - an old cattle droving route. Good going on grassy ridges over Mount Maw and the earlier half of the walk; much rougher and wetter on the heathery East Cairn Hill. Good going once more on the Thieves' Road.
