Visitors to Johnston Ridge Observatory can enjoy multiple award-winning films, listen to ranger talks, observe the landscape, purchase souvenirs, set off on a hike, or get a light lunch from the food cart.
Check out the annual summer Music on the Mountain series held throughout summer at the Johnston Ridge Observatory outdoor amphitheater (in partnership Mount St. Helens Institute).
