Muck is the smallest, lowest-lying and southernmost of the four Small Isles off the west coast of Scotland. It measures about two and a half miles from east to west and covers just over two square miles in area. The island is owned by the resident MacEwen family, who farm the land and raise Highland ponies and sheep.
Tourism is a vital part of the island's economy, with near daily visits by scheduled ferries from the mainland during the summer. While the island's population remains stable at around thirty, it can swell to almost double that during the summer thanks to a variety of accommodation. The tranquility and small size of the island make it extremely popular with families. The small size of Muck is also said to contribute to the relative absence of midges than plague visitors to other larger islands.
