Recreation - Park visitors enjoy picnicking, camping, scuba diving, hiking and clamming.
Climate - The low rolling hills and sheltered inland salt water that make up the Puget Sound basin produce a mild, marine climate characterized by wintertime clouds, rain, and sometimes a light snow, but lots of summertime sunshine.
Maximum winter temperatures are in the mid- to high 40s with minimum temperatures in the mid 30s. Summers are warm with maximum and minimum temperatures in the mid 70s and low 50s, respectively. This area averages 51 inches of precipitation per year.
Saltwater State Park is located two miles south of Des Moines on State Route 509 in King County.
