I stopped at Mt. St. Helens while travelling from Seattle down to Oregon and had a great run on the trails. I spent more time on the trails than expected and hadn't made plans for a campground. I found Seaquest State Park in the NPS Gazette and drove in just as the sun was setting. I spent the night and although I didn't visit the entire park, it did seem like a nice, family oriented campground. The bathrooms were clean and while the campsites are relatively close together, there are sufficient trees and shrubs to maintain privacy. The bathroom facilities were satisfactory.
