On a scorching hot day, we took a six-mile trek to view the Mt St. Helen's up close. Wildfires from Canada and in the Pacific Northwest obscured the view (we weren't in any danger, as the fires were quite far off), but not the good time. The shear force of what this volcano did in 1980, and have the landscape has been changed was awesome! Access is easy, in that the roads are great. But it is a drive to reach. Cost is nominal.
