Goldendale Observatory
One of the largest, most accessible telescopes in the country
Goldendale Reached for the Stars
47 years after the construction of Goldendale Observatory, the first major renovation of this unique State Park was completed in February 2020. A much larger and more advanced learning center now stands in complement to the iconic main observatory dome and the newly upgraded telescope within. Seating capacity has more than tripled and self-guided interpretive exhibits are installed throughout the campus.
And Goldendale Touched Them
Since 1973 Goldendale has been home to a great treasure. Right on the hill overlooking town we have one of the largest and most accessible public telescopes in the nation. Thousands of star gazers, amateur astronomers, and students travel to Goldendale every year to meet the stars at Goldendale Observatory State Park.
Evening Program
Explore the magic of the Goldendale Observatory during their signature event. Attendees can enjoy an immersive stargazing experience, with expert staff on hand to answer astronomy questions. Don’t miss the chance to observe celestial objects through one of the world’s largest public telescopes. Remember to bring a jacket for the night sky adventure!
Afternoon Program
Attend an enlightening discussion about our local star, the Sun. During this one to two-hour show, you’ll experience high-resolution and contrast live views of the Sun—some of the best available at any public observatory or science center. By the end, you’ll have a deeper understanding of the stars!
