Interpretive opportunities
Seaquest is connected to the Mount St. Helens Interpretive Center by a short pedestrian tunnel. The Interpretive Center features a fun, interactive educational experience focusing on the May 1980 eruption of Mount St. Helens and subsequent regrowth. It also offers visitors a sweeping view of Mount St. Helen's National Volcanic Monument, 47 miles east of the park in the Gifford Pinchot National Forest.
Trails
Seaquest features more than 12 miles of hiking trails. A boardwalk trail beside the Interpretive Center connects visitors with wetland shoreline for an unobstructed view the volcano and surrounding woods.
Birdwatching
Silver Lake at Seaquest is a shallow wetland lake that is home to many species of birds and wildlife.
Campsite information
The park has 52 standard campsites, 18 partial hookup sites, 15 full hookups sites, three hiker/biker sites, one dump station, five restrooms (four ADA), and six ADA showers.

Outside is a picnic table and fire pit with grate. All yurts are heated, but visitors should take along blankets and warm clothing as evenings can be cool. Tents are not allowed on the yurt site, but awnings are okay. For more information, visit the cabins/yurts page.
