Visit Mt. St. Helens with a naturalist guide who will discuss the geology, ecology, climate, history, and legends of the area, as well as the history of US public lands. You will hike near waterfalls, through lava tubes, and within old-growth forests and see some of the most unique geological features in North America, including North America's longest continuous lava tube and a lava tree mold forest. Weather permitting, you will be driven to the closest viewpoint into the crater of the volcano, where you will be provided a picnic lunch overlooking Spirit Lake. No matter how hot the weather, you'll enjoy natural air conditioning as you hike by dramatic waterfalls and through the primeval forest.
