Saltwater State Park RV & Campground Guide


Saltwater State Park is a beach near Washington state’s largest urban area, and is an easy getaway to escape the hustle and bustle of the city! The park is just two miles from Interstate 5, on the shoreline between Seattle and Tacoma, making it one of the state’s most popular parks. Visitors can wade in the shallows and explore the tidepools, make sand castles, or look for seashell treasures along the shore. Depending on the season, they might also see salmon spawning in McSorley Creek. Saltwater is also the only state park with an underwater artificial reef for scuba diving. The reef is a protected marine sanctuary. 

Weather at the park can be chilly, and since it’s on the ocean, the marine layer of fog is always a consideration! Temperatures in the winter can range from an average of 51-34F, and in the summer the average high gets up to about 78F.
