A 15km long freshwater loch that's just over 1km wide and 130m deep. Loch Rannoch was once surrounded with old Caledonian pine forest; the Black Wood of Rannoch is one of the largest remnants of this ancient wood.
The roads along both sides of the loch are quiet and fine to walk on with interesting adventures to be had north, south or west. Kinloch Rannoch at the eastern end of the loch is the largest settlement with pubs and a shop for supplies.
