Nestled conveniently between the bustling cities of Seattle and Tacoma, this 137-acre marine park is a true gem, boasting 1,445 feet of Puget Sound shoreline, a sandy beach, intriguing tide pools, and a lush network of forested trails. Its most distinctive feature, however, lies beneath the waves: Washington's only artificial underwater reef, making it a premier destination for scuba diving and snorkeling enthusiasts.

Why Visit Saltwater State Park

We often get asked, "is Saltwater State Park worth visiting?" Our answer is an unequivocal yes, especially for those seeking a diverse outdoor experience without venturing far from urban centers. This park offers a remarkable juxtaposition of serene natural beauty and thrilling underwater exploration. Imagine spending your morning beachcombing along a driftwood-strewn shore, then donning your scuba gear to explore a vibrant artificial reef teeming with marine life.

The park's historical significance, as a symbolic peace offering between Seattle and Tacoma dating back to its 1926 dedication, adds another layer of intrigue to your visit.

Beyond its recreational appeal, Saltwater State Park serves as a vital marine protected area, where the artificial reef has fostered a thriving ecosystem of sea stars, urchins, anemones, scallops, rockfish, and even the elusive ling cod, which can grow up to five feet long. This commitment to conservation ensures that every visit contributes to the preservation of Puget Sound's delicate marine environment. For those considering if Saltwater State Park is worth visiting, we highlight its exceptional accessibility, diverse activities, and significant ecological value as compelling reasons to add it to your Washington itinerary.

Who It's Best For

Our team believes Saltwater State Park truly shines for a diverse range of visitors. It's an ideal spot for families with children, offering safe beach access, playgrounds, and fascinating tide pools to explore at low tide. Kids will love building sandcastles, wading in the shallows, and discovering small marine creatures.

For outdoor enthusiasts, particularly scuba divers and snorkelers, this park is a must-visit. The artificial reef is a world-class dive site, attracting divers from across the Pacific Northwest eager to witness its abundant marine life. Hikers will appreciate the cool, forested trails that wind along McSorley Creek, offering a refreshing escape and opportunities to spot seasonal salmon spawning.

Nature photographers will find endless subjects, from the dramatic Puget Sound vistas to the intricate details of tide pool inhabitants and the lush forest canopy.

Even those simply looking for a peaceful escape from the urban hustle of nearby Seattle or Tacoma will find solace in the park's tranquil atmosphere, especially during weekday mornings.

Getting There & Parking

Understanding how to get to Saltwater State Park is straightforward, making it an incredibly accessible destination. The park is conveniently located just two miles from Interstate 5, making it an easy drive from both Seattle (approximately 30 minutes north) and Tacoma (approximately 20 minutes south). If you're coming from Seattle, we recommend taking I-5 South to Exit 149 (Kent-Des Moines Road) and following the signs. For those traveling north from Tacoma, take I-5 North to the same exit. All roads leading to and within the park are paved and well-maintained, ensuring a smooth journey regardless of your vehicle size.

Once you arrive, parking is readily available in the day-use area near the beach. However, it's important to note that a Discover Pass is required for vehicle access to Saltwater State Park. You can purchase a one-day pass for $10 or an annual pass for $45. These passes can be acquired online, by phone, or in person, and are essential for parking at any Washington State Park. If you've already paid for camping within a Washington State Park, the Discover Pass fee is waived for day-use parking. We always advise checking the Washington State Parks website for the most current fee information and any potential alerts, especially during peak seasons when the park can draw significant local crowds on summer weekends.

Top Things to Do

There are countless things to do at Saltwater State Park, catering to every type of outdoor enthusiast. Our team has explored every corner of this park, and we can confidently say you won't be bored. The park's main draws revolve around its stunning Puget Sound shoreline and its unique underwater world.

Underwater Exploration: Scuba Diving & Snorkeling

Saltwater State Park is renowned as the only state park in Washington with an artificial underwater reef, making it a prime location for scuba diving and snorkeling. Descend into the cool waters to discover a thriving marine sanctuary, where fishing and shellfish harvesting are strictly prohibited to protect the delicate ecosystem. Divers frequently encounter a spectacular array of marine life, including vibrant sea stars, colorful urchins, graceful anemones, and schools of rockfish. Keep an eye out for larger inhabitants like ling cod, which can reach impressive sizes, and even the occasional giant Pacific octopus or wolf eel. We recommend this dive for advanced divers due to variable depths, ranging from 30 to 100 feet, and the potential for strong currents. A convenient scuba wash station is available near the beach for cleaning your gear after your dive.

Beach Activities & Tide Pooling

For those who prefer to stay above water, the park's 1,445 feet of sandy beach offers ample opportunities for relaxation and recreation. Spend your day building sandcastles, wading in the shallow waters, or simply soaking up the sun. The driftwood-strewn shore provides a picturesque backdrop for beachcombing, where you might discover unique treasures washed ashore. At low tide, the park's tide pools reveal a fascinating microcosm of marine life. Our team loves exploring these natural aquariums, where you can observe small crabs, sea anemones, and various shellfish in their natural habitat. Remember to look, but not touch, to preserve these delicate ecosystems.

Exploring Saltwater State Park Hiking Trails

Beyond the beach, Saltwater State Park offers a network of forested hiking trails that provide a refreshing contrast to the marine environment. The trails wind through lush second-growth timber, following the course of the salmon-bearing McSorley Creek as it carves through steep ravines. One of our favorite options, and an excellent introduction to the park's terrestrial beauty, is the North and South Rim Trail Loop. This easy 2.0-mile (3.2 km) loop boasts a gentle 118 feet (36 meters) of elevation gain and can typically be completed in about 51 minutes, making it wonderfully accessible for all ages and fitness levels. Along the Saltwater State Park hiking trails, you'll enjoy tranquil forest views and, if you visit during the right season, you might even spot salmon making their way upstream to spawn in McSorley Creek. For a slightly longer walk, the Des Moines Creek Trail loop, starting from Des Moines, offers an easy 3.4-mile (5.5 km) journey through a similar creek-side environment.

Picnics & Day Use

Saltwater State Park is exceptionally well-equipped for day use, with numerous picnic areas perfect for group gatherings or a quiet meal by the water. The park features 147 unsheltered picnic tables available on a first-come, first-served basis, many of which are situated near the beach or in the shade along McSorley Creek. For larger groups, two picnic shelters are available for reservation by calling (888) 226-7688. While wood fires are strictly prohibited throughout the park, including in the picnic areas, propane and gas grills are permitted for cooking. A seasonal snack shack operates daily from Memorial Day weekend to Labor Day, and on weekends in April, May, and September, offering burgers, hot dogs, nachos, and beverages.

Wildlife Viewing & Photography

The park's diverse ecosystems provide excellent opportunities for wildlife viewing. Above water, keep an eye out for various bird species, including eagles, herons, and gulls. Below the surface, the artificial reef is a haven for marine creatures, offering fantastic chances to observe sea stars, anemones, and a variety of fish in their natural habitat. During the fall, you might even witness the incredible spectacle of salmon spawning in McSorley Creek.

Best Time to Visit

The best time to visit Saltwater State Park largely depends on your desired activities. The day-use area of the park is open year-round from 8:00 a.m. to dusk, offering access to the beach and trails regardless of the season. However, certain amenities and activities are seasonal.

For optimal beach activities, swimming, and picnicking, we highly recommend visiting during the summer months, from Memorial Day weekend to Labor Day. During this period, the seasonal snack shack is open daily, and lifeguards are typically on duty from 9 a.m. to 5 p.m., weather permitting. Summer weekends can be quite busy, drawing significant local crowds, so for a quieter experience, consider visiting on weekday mornings.

Scuba diving is a year-round activity, though conditions can vary. Experienced divers often brave the colder waters outside of summer for potentially clearer visibility. For those interested in marine life, the artificial reef is consistently vibrant. If you're hoping to witness salmon spawning in McSorley Creek, the fall months are your best bet.

Spring and fall offer pleasant temperatures for hiking the forested trails and exploring tide pools, often with fewer crowds than in the peak summer season. The snack shack also operates on weekends in April, May, and September. Winter visits can be peaceful, but be aware that some facilities, like restrooms, may have limited services outside of the summer season. Always check the Washington State Parks website for any seasonal closures or operational changes before your visit.
