• Objects viewed through facility telescopes may include those mentioned in "What's Up."  

• Be sure to also check the Weather & Moon when making plans to visit.
• DRESS WARMLY, NO MATTER THE SEASON:  The telescope domes are not climate-controlled and presentations often take place outdoors.  Observatory Hill can be cold and windy, even in the summer.   

• Admission is Free. However, a Washington State Parks Discover Pass is required to park on-site. These are available online and at all Washington State Parks, including the Observatory. FOGO members can choose a discount on their yearly Discover Pass.
