Ketchum's Dark Sky Reserve

The International Dark-Sky Association approved the nation’s first dark sky reserve in December of 2018. The 1,416-square-mile reserve includes the communities of Stanley, Ketchum and Sun Valley. It is the 12th such reserve worldwide, and the third largest!

Did you know that 80 Percent of Americans can’t see the milky way anymore? And yes, pollution is to blame. Our skies are so clouded now that most people will live their entire lives without getting an untarnished look at our amazing galaxy.

The International Dark-Sky Association’s designation requires public and private lands to “possess an exceptional or distinguished quality of night sky, view of the stars and nocturnal environment". The association gave the Central Idaho Dark Sky Reserve “Gold Tier” status, its highest ranking of the quality of the night sky.

Hotel Ketchum, situated in the heart of the International Dark Skies Reserve, is helping shed light on this amazing spectacle by adhering to the local outdoor lighting ordinance, working with the Idaho Conservation League to promote educational events and supplying visitors with all the essentials for a beautiful night of stargazing.
