    By far the best opportunity to see the volcano ... You will need to be the judge based on the 102 mile round trip to the Johnston Observatory on the Spirit Highway ... definitely a must for an only ever visit to the area. Visitor center indoor presentations are closed for renovation. Restrooms, limited indoor access, and all viewing areas and trails are open. Outdoor ranger programs appear to be going on.

  5. 4.5 Pierce College Science Dome (3 reviews)
    - Fantastic Outing at a Low Price!

    Pierce College Science Dome image
    We visited the Pierce College Science Dome last week with a middle school group from WAVA. What a wonderful experience! The Galaxy Guide gave us a wonderful tour of the night skies, including constellations, current research on exploration of the moon Europa, and a comparison of comets vs. asteroids. That was topped off with an amazing video on Black Holes. I am beyond impressed! All this for $35? This makes a great outing or field trip and what a fun birthday party for budding scientists!
