Mt. St. Helens Adventure Tour (Departure from Portland)

Marvel at the sublime magnificence of Mt. St. Helens, hike through an old-growth forest, spelunk through a lava tube and enjoy waterfalls on this tour through the Gifford Pinchot National Forest.

Travel north of Portland along the lower Columbia River, known for 18th-century Spanish, American and British explorers, and the Chinookan people. Crawl through a lava tree mold during a 20-minute hike in a landscape reminiscent of a fairy-tale amusement park, before beginning your descent into Ape Cave, one of the longest continuous lava tubes in North America. Spend up to 2.5 hours exploring this cave, named for a purported Sasquatch attack.

Weather permitting, you will spend an hour at the closest viewpoint into the crater of the volcano, where you will enjoy a picnic lunch while overlooking Spirit Lake. If there are no clouds, walk up the 437-step staircase to get a photo of Mt. Hood, Mt. Adams, Mt. Rainier, and, of course, Mt. St. Helens. Before returning to Portland, you'll make additional stops along the way to enjoy vistas, hike through old-growth forests and admire a waterfall. Throughout the day you will learn about the geological history that shaped Mt. St. Helens and the Cascadia region.
