Mount St. Helens National Volcanic Monument surrounds the iconic Mount St. Helens volcano, which rose to international prominence for its stunning 1980 eruption. The 110,000-acre natural area was established in 1982 to protect the region's sensitive natural areas that were affected by the eruption and to promote research into the environmental effects on the surrounding region.
Park visitors can scale the mountain's summit with special hiking permits or ascend its stunning Windy Ridge Overlook, which is considered to be one of Washington's top scenic drives. The volcano's Ape Cave lava tubes are also showcased along the park's National Recreation Trail Ape Cave Trail. Visitor centers throughout the park are home to interpretive trailheads, documentary films, and exhibits on the region's unique geology.
