Seaquest State Park RV & Campground Guide

Washington

The Seaquest State Park is located a few minutes off of Interstate 5 about halfway between Tacoma, WA, and Portland, OR. The closest city is Castle Rock, WA, which is six miles to the west. While July and August typically see little to no rain, the region sees an average annual rainfall of about 54 inches, with December and January being the wettest months. This state park sits on Silver Lake, which was formed when an early eruption of Mt. Saint Helens created a natural dam on the Silver Creek. The park includes wetlands and forested areas, so there's plenty of wildlife to view. Some spots on the hiking trails offer spectacular views of Mt. Saint Helens.
