Foula is a small island jutting out of the Atlantic Ocean off the northern tip of Scotland. The island is only 2.5 miles by 3.5 miles and is home to a mere 31 people. The island’s inhabitants traditionally made their living from fishing, but in recent years tourism and sheep herding have emerged as revenue generators. The island lacks a harbor, though a small airport makes getting to and from the mainland a relatively painless affair. On an environmental note, the lighthouse that warns ships away from the southern tip of the island is powered by wind and solar power. You can get a sense of the island through this video.
