Report: We went overnight and had a good time. We hiked around and mainly just hung out at the campsite. Good bathrooms/showers. It was quiet. It's great if you are just looking to hang out and relax. But there is not a lot to offer. No swimming, etc. But it's a great local spot for a get-a-away.

Report: Really enjoyed being so close to Mt St Helens. A very clean park. Excellent place for camping while spending the day elsewhere hiking or something. The campsites are gorgeous.

Report: We all thought this park was pretty lame. Freakin' gopher holes everywhere on the big grassy field. The big toy play area was so-so. The only thing that might redeeem this park is the trail which I didn't get to go on since the kids were so bored with this park within 10 minutes. Probably won't go back because we would much rather go to Lewis & Clark State Park which is not too far away.

Report: The one-mile boardwalk loop at the Mt. St. Helens Visitor Center is a highlight. Great chance to observe wildlife on Silver Lake! You can take the pedestrian tunnel under 504 for a few more miles of hiking through secondary forest on a maze of trails.
