The Trail of Two Forests is a parking lot with explanatory plates and a trail with a wooden boardwalk. The trail leads to a small lava tube and numerous tree molds. At least two of the tree molds are big enough to crawl through. One is called The Log Crawl.
The lava tubes and the tree molds were formed by a lava flow from Mt. St. Helens 1,900 years ago.
