Fingal's Cave, located on the uninhabited island of Staffa in the United Kingdom, is a marvel of natural architecture and a place shrouded in myth and majesty. While technically not a beach with expanses of sand, nor is it known for traditional beach activities like swimming or sunbathing, its unique geological features and coastline offer a different kind of allure. The cave's length, stretching about 227 feet into the earth and standing at about 72 feet tall, with naturally formed hexagonal basalt columns, creates a cathedral-like atmosphere that has been drawing visitors for centuries. The color inside the cave is a mix of dark basalt and light reflections off the water, creating a mesmerizing effect. Fingal's Cave has few amenities, so plan your trip accordingly, although it does have unparalleled natural beauty and the unique opportunity to explore a sea cave by boat or from the viewing points on the island.
