    Johnston Ridge Observatory Trail

    The Johnston Ridge Observatory has one of the best views of Mount Saint Helens you can earn without climbing anything. This very quick and simple walk takes you through the observatory over a half-mile with almost no elevation gain. Part of the trail is wheelchair accessible and the entire path is very family-friendly. If you want to experience the beauty of Mount Saint Helens with as little work required as possible, this is definitely the way! While you observe, you can learn about the history of the volcano, including the deadly eruption that occurred in 1980.

    There are restrooms at the observatory but no other amenities are available. Lodging, gifts, and food are available in nearby communities.

    Route Description for Johnston Ridge Observatory Trail

    Mount Saint Helens is simultaneously a beautiful natural feature, the subject of sobering history, and a point of speculation for the future. This active volcano infamously erupted in May 1980, killing 57 people and causing a billion dollars of damage. It was the most disastrous explosion in American history. Today, the volcano displays its massive crater, expanding lava dome, new glacier, and post-eruptive geological changes.

    The Johnston Observatory is the best place to appreciate Mount Saint Helens and to see how the mountain and the surrounding land were changed by the eruption. The observatory is perched on the Johnston Ridge, and the expanse of flat land between it and Mount Saint Helens provides an unobstructed view.

    This trail takes you on a short, easy route around the observatory grounds. This trail is quick, but you can explore the other side of the ridge which has more trails as well.

    Beginning from the parking area, head under the road and take the path down to the ridge. You’ll walk along the ridge to your right. This very quick trail ends as far as the path goes this way, but if you go back to where the trail splits at the ridge, you can walk along the trail on the other side even further.

    It’s impossible to miss the volcano in your view. Look at the crater, where within there’s an expanding lava dome and the newly formed glacier. Hikers are regularly climbing up to the crater rim.

    When you’re ready, head back to the parking area.
