Dark Sky Parks in WA

List of darkest places in Washington for stargazing, astrophotography, star parties, and club events. Often these are national and state parks and forests that are either remote or "protected" against light pollution.

National parks often let you stay overnight under the stars, hence their motto - "Half the park is after dark".

The IDA column indicates if a site is IDA-certified. Bortle scale for sites is given where known. Also use your local astronomy club for guidance as they will know the darkest places.
