Sark's designation as the world's first Dark Sky Island is not marketing — on a clear night, the sky above the island is extraordinary. Away from the Channel Islands' main towns and with no streetlights, the Milky Way stretches clearly overhead. The island is at its most dramatic for stargazing in winter, when the nights are longest and the atmosphere clearer.
Even the uninitiated can find the major constellations and star clusters without equipment. For serious astronomers, the island's amateur astronomical society occasionally hosts observing events. The combination of the boat journey, the car-free island, and the night sky makes for a genuinely unusual experience.
