Trail #233 Trail of Two Forests

Area Status: Open
This area is Open

Beginning from Trail of Two Forests Interpretive Site. Interpretive signs guide you through this lava flow from Mount St. Helens that engulfed and consumed a forest 1,900 years ago. The accessible boardwalk loop trail takes you to many examples of tree casts formed as lava flowed around trees and cooled, leaving impressions of the forest.

To protect fragile geologic features and plant life, please stay on the boardwalk.
