Cycling the Green River Trail-Interurban Trail Loop

In 2025, Yeung cycled the Green River Trail-Interurban Trail Loop, filming his full route on a GoPro. He says he loved exploring all the new sights along the way, including flights departing from the nearby airport.

“Seeing the parks and the close view of the planes is always a treat,” Yeung told us. “That it’s all car-free makes for a serene experience.”

You can watch the video he filmed and see his exact route on Ride with GPS. But first, read on to find out more about how to complete the route.

What is the Green River Trail?

The Green River Trail is a paved, 19-mile trail that winds along the banks of the Green and Duwamish Rivers, beginning at the southern border of Seattle and stretching to the city of Kent. Passing through Cecil Moses Park and Fort Dent in Tukwila before converging with the Interurban Trail, the trail transitions from industrial areas to lush, green views.

What is the Interurban Trail?

The Interurban Trail is a paved, nearly straight 14-mile trail beginning in Tukwila and stretching south to the town of Pacific. It follows along the historic Interurban Rail Line, which once took passengers from Tacoma to Seattle.

Where do the Green River Trail and the Interurban Trail connect?

On the north end, the Interurban Trail begins at an intersection with the Green River Trail at Fort Dent Way near Fort Dent Park. If you ride the Green River Trail about 12 miles south, it eventually converges with the Interurban Trail again at Foster Park in Kent, creating a loop for cyclists.

What if 20+ miles is too long?

We hear you! If you’re comfortable with biking on a street, you could stop just before Three Friends Fishing Hole Park and head east on S 200th St, which turns into S 196th St. It has a dedicated bike lane and will take you to the Interurban Trail. Your trip will be about half as long. Alternatively, you could begin your journey at Three Friends Fishing Hole, which has a parking lot.

There are several places to start the route. Yeung began his ride a bit earlier than most, on the Lake to Sound Trail in Renton, though this will add several miles to your trip. If you want to skip that part, you can begin at Fort Dent Park, which has a parking lot. Alternatively, the Tukwila Park & Ride, which is about a 10-minute ride from Fort Dent Park, also has many parking spots. (You could also start your ride from the southern tip of the loop and park at or near Foster Park in Kent, though this guide begins on the north end).

From Fort Dent Park, ride south on the Green River Trail, passing through industrial areas that eventually open into wide green spaces. In the summer, you’ll see plenty of leafy green trees and several small parks where you can stop and rest, including Tukwila Park and Bicentennial Park. On a clear day, you may even catch views of Mt. Rainier. Just keep in mind that you share the path with joggers, dog walkers, and strollers, so be sure to give them space.

From where Yeung began, it took him about 14 miles to get to the southern end of the loop. From that point, just take a left and head north on the Interurban Trail! It's pretty straight and flat, so you can glide on north with ease. In about 40 minutes, you’ll be back at Fort Dent Park.

If you’re up for a short detour, there are many places to eat in the Tukwila business district. Oppegaard, a locally owned meadery tucked away in an industrial park, feels like an ancient hall inside. Pull a board game off the shelf, order a mead flight, and unwind.

For a quick bite, head to Lam’s Seafood Asian Market, which has an eatery inside so you can choose from many options. We love Natalie’s Sugar Cane & Dessert for refreshing drinks made with fresh fruit and unique Vietnamese street food options. Other shops inside offer banh mi, mochi donuts, and pho.

Want the cheapest possible option? Costco in Tukwila may not be the first stop that comes to your mind, but cyclists say that when you’re with a group, it’s a great place to grab a whole pizza for cheap, and it’s directly off the trail.

Still have energy for fun? The Interurban also passes near Family Fun Center, where you can race go-karts and bumper boats and play arcade games. Don’t let the name lead you to believe it’s only for kids. It’s a popular spot for groups of all ages and has a full-service restaurant inside.

Just a few minutes north of Fort Dent Park, there’s a restaurant at Foster’s Golf Links, Billy Baroo's has fantastic outdoor seating that overlooks the forested greens.

If you keep biking about five minutes north of Fort Dent Park, a large, striking piece of public art is tucked away in an unlikely place along the Interurban Trail: Tukwila’s Interurban Pump Station. Water Carry by Seattle sculptor Claudia Fitch, which is integrated into the station’s staircase, depicts the history of the nearby Duwamish River. There are basket-like sculptures that double as seating (feel free to walk up and take a rest). Then explore the steps to read the text on the ground, which describes the site’s connection to history and water.
