Hikes in Mount Saint Helens National Volcanic Monument

When Mount Saint Helens erupted in in 1980, it instantly became America’s most well known Volcano. Over 200 square miles of forest were scorched, 250 homes were burned, and 57 people were killed. Evidence of the powerful eruption and previous volcanic activity can be witnessed on trails around Mount Saint Helens. Two years after the eruption, Mount Saint Helens National Volcanic Monument was established to help preserve this area and monitor its recovery. The monument is managed by the US Forest Service as part of the greater Gifford Pinchot National Forest. At the south end of the park there are several interesting trails through terrain shaped by Mount Saint Helens.
