4 Comments on “Seaquest State Park”

  1. Joodie Klinke says:

    We stayed here June 2015 in our 24′ Chinook Destiny. Our rig was fine for the regular campground, but bigger rigs will need to use the dedicated RV loop. Seaquest is the park to stay at if you’re going to visit Mt. St. Helens (you’ll need a tow vehicle if you don’t want to drive your rig since the park is 50 miles away from the mountain.) We enjoyed the many trails in the park, and the 1-mile trail and boardwalk around Silver Lake, from which you can see the mountain. The Silver Lake Mount Saint Helens Visitor Center is across the road, accessed by a tunnel under the highway. There is also a coffee and shave ice stand outside the visitor center that was open on the weekend. Two complaints while we were there: no doggie bags and the swingset in the playground closest to us was in serious need of oil!

  2. Bill McDaniel says:

    which campsite is the camp host?

    • HI Bill,
      Not sure, perhaps someone here has an answers. All we were able to identify is a ‘Yurt Host’ site (see Campground Map).

    • Debbie Combs says:

      Camp host site is T7 and the Yurt Village host site is next to the Yurts at the end of the Day Use area.
