A pedestrian tunnel connects lush, forested Seaquest State Park with its more well-known neighbor across the road, the Silver Lake Mount St. Helens Visitor Center. The park makes a topnotch base for an exploration of the famous Washington volcano.

The visitor center is a destination unto itself. Ranger talks, documentary film showings, naturalist-led hikes and interpretive exhibits bring to life the mountain's geology and history. It's a tour through time, from prehistory to the earth-altering 1980 explosion and the area's recovery.

Unwind from touring by strolling through Seaquest, where dappled sunlight streams through secondary old-growth trees. Hiking and biking trails abound, and a children's playground features a human-made sand dune that will keep kids occupied for hours. A trail and boardwalk around the wetlands of Silver Lake offer birding and volcano views.

If you're headed to the U.S. Forest Service's Johnston Ridge Observatory, this state park will leave you with a deep appreciation for the resilience of nature – and a new context for what you will see as you travel closer to the mountain.

Mount St. Helens programs

The Mount St. Helens Visitor Center is located across the road from the park entrance. It was incorporated into the state park system in October 2000. The center focuses on information about the volcano and features a first-rate exhibition hall. Formal programs last approximately 15-20 minutes and introduce visitors to the ecology, history, native American culture as well as the 1980 eruption sequence of Mount St. Helens; the most active volcano in the Cascade Mountain Range. Visitors of all ages are welcome to join.
