OR dark sky places
List of darkest parks and places in Oregon for stargazing, astrophotography, astrotourism, star parties, and astronomy club events. Often these are national and state parks and forests that are either remote or "protected" against light pollution.
National and state parks often let you stay overnight under the stars, hence their motto - "Half the park is after dark".
Bortle scale for sites is given where known. Also ask your local astronomy club for guidance as they will know the darkest places.
