Kentra Bay, also known as the Singing Sands, is a remote tidal, 306° orientated, coastal embayment located on the northern shore of the Ardnamurchan peninsula, at the extreme eastern side, where it meets the mainland proper, near Acharacle, in the western Highlands of Scotland. Kentra Bay contains a large expanse of mudflat at low tide and small fragments of salt marsh, sand dune, and machair. Kentra Bay is an inland bay separated from the sea via a channel at the northeast side.
