Saltwater State Park

Saltwater State Park is a marine protected area on Puget Sound spanning roughly 137 acres of forested land. The site offers access to rocky and sandy beaches with tidal pools and shallow waters where visitors can observe sea stars, urchins, and other creatures.

The site was established by the Washington State Parks Commission as a nature reserve and gained Marine Protected Area status in 2009. This designation aimed to safeguard marine life and ecosystems from overuse.

The site takes its name from the saltwater environment that defines the landscape and draws visitors seeking connection with marine life. People come here to explore tidal zones and observe sea creatures in their natural settings.

The park is open year-round, starting in the morning and closing at dusk. Visitors should check tide tables to find the best times for exploring tide pools and the shoreline safely.

An artificial underwater reef draws scuba divers who can observe sea stars, urchins, anemones, and ling cod in their underwater habitat. This built structure has become a productive refuge for marine life and regularly attracts visitors with diving equipment.
