Discover the raw beauty and resilience of nature on the Hummocks Trail, a unique hike through the dramatic aftermath of the 1980 Mount St. Helens eruption. This 2.4-mile loop winds through an otherworldly landscape of volcanic debris, wetlands, ponds, and young forests that have emerged from devastation.

Named after the massive mounds of earth—called "hummocks"—that were blasted from the mountain’s north flank, this trail offers hikers a rare, up-close view of how ecosystems recover and evolve. Interpretive signs along the way tell the story of the eruption and the area's gradual regrowth.

The relatively flat trail is great for families, casual hikers, and nature lovers. Expect stunning views of Mount St. Helens on clear days, and watch for wildlife like elk, frogs, and birds that now call the area home.

Whether you're here for a peaceful nature walk, birdwatching, or a striking glimpse into geological history, Hummocks Trail #224 is a must-do hike in the Mount St. Helens National Volcanic Monument.
