Updated May 10, 2026

If you've ever tried to plan hiking in Saltwater State Park, you know how quickly the options can feel overwhelming. It's tough to tell which routes are genuinely worth your time and which are just filler. That's where we come in: our komoot community has explored, mapped, and reviewed these trails, so we've sifted through the options to bring you a curated shortlist of the best.

Hiking in Saltwater State Park offers a unique blend of coastal forest and saltwater shoreline along Puget Sound. You'll find trails winding through a ravine carved by the salmon-bearing McSorley Creek, surrounded by lush second-growth timber, with a good mix of easy and moderate routes. Expect gentle climbs and descents, and if you visit in the right season, you might even spot salmon in the creek.

If you only do one hike, we'd start with the North and South Rim Trail Loop, an easy 2.0 miles (3.2 km) that gives you a fantastic overview of the park's forested ravine. For a slightly longer, equally accessible walk, the Des Moines Creek Trail loop from Des Moines is an easy 3.4 miles (5.5 km) that follows the creek-side environment. With more than 170 hikers having used komoot to explore here, you're in good company to discover your next favorite trail.
