Dark Sky Initiative

The award-winning International Dark Sky Places (IDSP) Program was founded in 2001 to encourage communities, parks and protected areas around the world to preserve and protect dark sites through responsible lighting policies and public education.

As of February 2020, there are over 130 certified IDSPs in the world. See where they are located on our interactive map.

IDA designates IDSPs following a rigorous application process requiring applicants to demonstrate robust community support for dark sky protection and document designation-specific program requirements.

Applications are reviewed bimonthly by an IDA standing committee composed of dark sky experts and previously successful program applicants. Regular status updates ensure that designated places continue their commitment to dark sky preservation.

Upon certification, IDA works with certified places to promote their work through media relations, member communications, and social media. An International Dark Sky Place designation helps enhance the visibility of designated locations and foster increased tourism and local economic activity.
