​September and October are prime months for salmon-watching in Western Washington. After years in the ocean, adult salmon return during these months through Puget Sound and into local rivers and creeks to spawn. The timing varies by species and watershed, but fall brings Chinook and coho into many area waterways, with chum following later in the season.
Pink salmon also spawn in the fall, but their major Puget Sound runs occur in odd-numbered years. That means that now is your chance to see one of the Northwest’s great natural cycles happening close to home. The spots below give you a bird’s-eye and often even closer view as salmon push against the current, gather in pools, or as females sweep gravel aside with their tails to make nests. Give the fish plenty of room and stay out of the stream bed.

Issaquah Salmon Hatchery
We visit the Issaquah Salmon Hatchery every year so our daughter can see and feed fish. This is one of the easiest spots to safely watch the salmon in Issaquah Creek, which runs right through the hatchery. Kids can also feed the fish in the hatchery tank (the gift shop sells fish feed). If you want your kids to really learn about the life cycle of Pacific Northwest salmon and how we can protect it, this is your first stop. A small aquarium with salmon fry (4- 12-week-old baby salmon) is a kid favorite. Pair it with playtime at the Gibson Park playground, located right behind the hatchery across the road. The hatchery also hosts an annual Salmon Days Event during the first weekend of October, in honor of the Pacific Northwest salmon’s homecoming.

We heard this spot is a terrific one to catch fish in action, but when we visited during the second week of September to get a look at Salmon, but no luck. According to the Seattle Aquarium, the best time to spot Salmon in this river is in October, when sockeye, chinook, and coho salmon return to to spawn.

Renton Library
Renton Library is built over the river and is an amazing spot to watch salmon runs with kids. The fact that it’s in a library only makes the outing more adventurous. Best watching here is from October-November, when numbers peak.

Tolt McDonald Park Bridge
The hanging bridge in Tolt McDonald Park spans the Tolt River and offers a nice view of the river, where you watch for the salmon run. Although it’s not a guaranteed spot for viewing fish, they do move through these waters and eventually upstream to the lake to spawn. The park also has a playground, a vast lawn area for free play, and reservable campsites. Add this spot along with a farm visit in the Carnation area during the fall.

Rocky Brook Falls
Editor’s Note: A visit in October 2026, revealed Rocky Brook Trail is currently closed with no re-open date listed. Check Washington Trails Association before you head out.Â
We visited Rocky Brook Falls in Brinnon the second week of October in 2025. It is a short 0.3-mile round-trip hike to the falls from the roadside parking lot. The trail is on private property, and signs suggest staying on the trail since it’s a hydroelectric facility. So we had to be mindful and keep our child from wandering off. Â My child was super excited to see the salmon in Rocky Brook Creek, which eventually flows into the Dosewallips River. There were so many fish in the creek and before getting into the car, we stopped at the river crossing bridge for a better view of the fish.
