Ardnamurchan is a remote, mountainous region with only one access road; it terminates in Ardnamurchan Point and Corrachadh Mòr, the western-most points of the British mainland. In the north-east of the peninsula two unnamed sub-peninsulas almost encircle Kentra Bay, and are bound by the South Channel of Loch Moidart to the north; to the east of this lies the River Shiel and then Loch Shiel, a long loch which forms most of this section of the border with Inverness-shire. Morvern is a large peninsula and like its northern neighbour is remote, mountainous and sparsely populated. In its north-west Loch Teacuis cuts deeply into the peninsula, as does Loch Aline in the south. At the estuary of Loch Teacuis lie the large islands of Oronsay, Risga and Càrna. There are numerous lochs in northern Argyll, the largest being Loch Doilet, Loch Arienas, Loch Teàrnait, Loch Doire nam Mart and Loch Mudle.
