The Mt St Helens Adventure Tour from Portland

The Mt St Helens Adventure Tour from Portland

star-5
18
Discover lava tube caves, old-growth forests, waterfalls, and more on a guided tour of Mt. St. Helens. The park’s vastness and variety of attractions can be overwhelming on your own, but by visiting with a guide you don’t miss any of the highlights. Plus, you can learn about the area’s geology, ecology, and history—much of which you might miss if visiting the park on your own.
