This road follows the shore of Doo Lough, a picturesque mountain lake nestled between the steep slopes of the Mweelrea range and the Sheeffry Hills. The landscape is desolate, rugged and impressively open, with constant views of the dark water of the lake. The road winds gently along the shore and feels remote, even though it remains very passable.

One of the most characteristic Connemara roads: narrow asphalt, slightly undulating, and constantly accompanied by water and low green ridges. Lough Fee lies elongated and open in the landscape. The road runs close to the banks, giving you almost continuous views of water, bog, and the surrounding hills. It feels remote and serene, with broad west coast air and an almost timeless tranquility.

Long, narrow mountain lake in the northwest of Connemara, formed in a glacial valley between the Mweelrea massif and the lower ridges towards Letterfrack. The water lies in a quiet, remote valley where peat, heather and rock alternate. The shores are largely uninhabited, giving the lake a distinctly wild and natural character.
