Doo Lough - the "lake of dark waters" - is already part of County Mayo. It is bounded by Sheeffry Hills to the east and by Mweelrea to the west. Although technically located just beyond Connemara boundaries (which are approximate and indefinite) this wild place has an incredible and quite a primordial appearance. The area is uninhabited (apart from the inevitable blackfaces), and at a first glance, you can believe to be in the Valley of Creation, where all things were born in the mists of time and the earth had not yet been trodden by human foot.
