The islands of Scotland's west coast are known collectively as the Hebrides; the Inner Hebrides are separated from the Outer Hebrides by The Minch to the north and the Sea of the Hebrides to the south. The Inner Hebrides that lie respectively north and south of Ardnamurchan are administered by two separate local authorities as part of larger territories. The northern Inner Hebrides, including Skye, the Small Isles and the Summer Isles, are part of the Highland unitary council region. The southern group, including Islay, Jura, the Slate Islands and Gigha are part of the Argyll and Bute council region.
