Time: 4-6 hours I’M sitting in the shelter of a twelve-foot-high cairn. Obviously, from its construction and dimensions and the fact that it tops a rather insignificant hill that is neither a Munro or Corbett, it is of some antiquity. A smaller, less ancient cairn lies about twenty paces away. Mist has turned the world into monochrome and the grouse are grumbling all around me. Twenty yards away a mountain hare lifts its head from the long tufts of grass and appears to be quite undisturbed by my presence. He has a boldness about him – or perhaps it’s just my fertile imagination. Mountains hares are notorious creatures of myth and magic.
