Best time to visit Saltwater State Park

Late June through early September is the prime window, with dry weather, warmer Puget Sound temperatures, and long daylight hours ideal for beach days and camping. July and August bring the busiest crowds, so reservations are strongly recommended for summer weekends. May, early June, and September are excellent shoulder-season options with cooler temperatures, lower demand, and easier campsite availability. Winter visits are possible for day use, but expect frequent rain, shorter days, and limited campground services.

Things to do at Saltwater State Park

  • Saltwater Beach and Tidepooling Easy
    RV parking available

    The park's main draw is its sheltered pebble and sand beach along Puget Sound, ideal for low-tide exploration. Visitors can spot sea stars, crabs, and anemones in the tidepools, and beachcombers will find driftwood and shells along the shore.

  • Underwater Park for Scuba Diving Moderate
    RV parking available

    An artificial reef offshore creates one of the most popular shore dives in south Puget Sound. Divers access the site directly from the beach and can expect to see rockfish, ling cod, and invertebrates. A Discover Pass and proper training are required.

  • McSorley Creek and Forest Trails Easy
    RV parking available

    A short network of wooded trails climbs the ravine behind the beach, following McSorley Creek through second-growth forest. The loops total several miles and provide a quieter contrast to the busy beach area.

  • Picnicking and Day Use Easy
    RV parking available

    Grassy picnic areas, tables, and kitchen shelters sit just above the beach, making Saltwater a popular spot for group gatherings. Large day-use parking lots accommodate cars, trailers, and smaller RVs.

  • Saltwater Shore Fishing Easy
    RV parking available

    Anglers fish from the beach for salmon, flounder, and perch when seasons are open. A current Washington state fishing license is required, and regulations vary by species and season.

  • Birdwatching Along Puget Sound Easy
    RV parking available

    The park's mix of shoreline, forest, and creek habitat attracts a wide range of birds, including bald eagles, great blue herons, kingfishers, and various shorebirds. Early morning is the best time to spot wildlife from the beach or the bluff-top trails.

  • Campground Overnight Stay Easy
    RV parking available

    Saltwater's forested campground sits just inland from the beach, putting overnight campers within walking distance of the shoreline. Sites include standard amenities such as picnic tables, fire rings, and access to restrooms with showers.

We had such a great weekend camping in the Memory Maker! Danielle has thought of everything when it comes to making life easy while you are “roughing it”. We felt cozy and comfortable sleeping as a family of 5. It was easy to pull behind our Tahoe as well. Great experience all around, we already have our next trip booked!

Phil G. - Aug 2025

Danielle is a great host! The trailer was wonderfully laid out and perfect for a family of four. It was very clean and everything worked perfectly! Our family had a great time and would definitely rent from Danielle again!

How to get to Saltwater State Park

The park sits just off Marine View Drive South between Des Moines and Federal Way, about a 20 to 25 minute drive (roughly 20 miles) south of downtown Seattle via I-5 and SR-509, and about 25 minutes north of Tacoma. The nearest airport for fly-and-rent trips is Seattle-Tacoma International Airport (SEA), only about 10 miles away. RV drivers should note that the final descent from Marine View Drive into the park is steep and winding with tight turns, so larger rigs should take it slowly, watch for low branches, and avoid the inner beach-area loops when towing. I-5 through the Seattle-Tacoma corridor is heavily congested at peak commute hours, so plan arrivals outside rush windows.
