About Seaquest State Park

Seaquest is a 475-acre state park on the western side of Silver Lake, set among tall firs with views of Mount St. Helens. The park has forested campgrounds, more than 12 miles of hiking trails, and a boardwalk over a wetland where birds and other wildlife gather. A pedestrian tunnel links the park to the Mount St. Helens Visitor Center, which has interactive exhibits on the 1980 eruption and its aftermath. Amenities include yurts, a group camp, picnic shelters, and a playground.
