Cottonwood Canyon State Park is a true gem and a wonderful place to go stargazing! There are areas for telescopes and cameras, but camping space is limited, so make sure to reserve your spot early!
Cottonwood Canyon has a limited number of camping spots and can be a bit isolated from other lodging areas, so make sure to book early. This remoteness also makes the park a great place for astronomy since it is so dark. Cottonwood Canyon is almost 1/2 way between Portland, OR and the John Day Fossil Bed Monuments, with the drive being about 2 hours to each location.
The Cottonwood Canyon State Park has a Bortle light pollution scale color of Black, which means great seeing! It is open to the public, but is in incredibly hard to get a cabin as there are only 4 cabins. Make sure to reserve the spots early! One can bring any astronomical gear available.
