About Goldendale Observatory
Goldendale Observatory sits on 5 hilltop acres, 2 miles north of the town of Goldendale and about 13 miles north of the Columbia River. The observatory houses one of the world’s largest publicly accessible permanently mounted telescopes. Last year, State Parks completed work on an extensive multi-year renovation of the observatory and grounds. Work included:

  • Converting the old Cassegrain telescope to a Newtonian telescope by replacing the telescope’s original mirror with a new, state-of-the-art 24.5-inch mirror.
  • Constructing a new building with a 140-person capacity auditorium.
  • Creating new exhibits on astronomy and other sciences.
  • Adding special lighting in the interior and outdoor landscape to preserve dark-sky viewing.
  • Increasing parking and restroom capacity.
