Our forest learning center is located just inside the blast zone on the Spirit Lake Memorial Highway in Washington State. It tells the story of Mount St. Helens and the remarkable recovery of forests, fish and wildlife following the eruption. The center is a partnership of Weyerhaeuser, Washington State Department of Transportation and the Rocky Mountain Elk Foundation.


  • Exhibits are open seven days a week 10 a.m. to 4 p.m. from Friday, May 18 to Sunday, Sept. 9.
  • Gift shop, restrooms and outdoor amenities are open daily 10 a.m.-5 p.m., from March 23 through October.

Admission to the learning center and surrounding grounds is free. The center is designed to accommodate disabled visitors (except the forest trail) and wheelchairs are available.
