International Dark Sky City

On October 24th, 2001, the City of Flagstaff became the World’s First
“International Dark Sky City.”

Come to FDSC for the best in dark skies information and recommendations!

The designation was awarded by the International Dark-Sky Association (IDA), a tax-exempt non-profit organization dedicated to preserving and protecting the nighttime environment and the heritage of dark skies. The International Dark-Sky City designation is given to identify towns and cities “with exceptional commitment to and success in implementing the ideals of dark sky preservation and/or restoration, and their promotion through quality outdoor lighting.”
