Portland: Mount St. Helens Full-Day Tour｜United States

Enjoy a full-day tour of Mount St. Helens with a naturalist guide, and discover one of the region's most iconic and powerful attractions.

Try spelunking at Ape Cave, the largest continuous lava tube in the continental United States, and explore the visitor centers in and around the Blast Zone. Stop to take scenic photos while your naturalist guide presents dramatic evidence of how the ecosystem is recovering from the 1980 eruption, and see how the reforestation project is progressing.

Just 5 miles from the crater, at Johnston Ridge Observatory visitor center, take in stunning views of the steaming volcano, the growing lava dome, and the world's youngest glacier.

Your guide will share the drama of the geological events surrounding the eruption, telling stories as you walk. Learn how volcanoes are monitored and discover how Mount St. Helens has taught new answers to old mysteries, all the while keeping an eye out for deer, elk, beavers, otters, and an array of birds.
