This ¼ mile long boardwalk trail leads you over a 2,000 year-old lava flow from Mount St. Helens. Lava ran through the forest and around trees, which burst into flames. The lava solidified around the trunks and trunks rotted away, leaving tree wells, voids in which the impressions of the bark remain. Interpretive signs along the route tell the story of this ancient event. Climb down a ladder and through a dark, tree well. Enjoy today’s forest of fir, hemlock, and brilliant, green moss growing on the old lava. The boardwalk is accessible and kid friendly. Picnic tables and a pit toilet are available.
To protect fragile geologic features and plant life, please stay on the boardwalk.
