Drive south on Bellevue Way toward the Mercer Slough Blueberry Farm and you'll hit the same quirk every local eventually learns the hard way: there's no left turn into the parking lot. If you're headed south, you have to pass the entrance, make a U-turn at the South Bellevue Park and Ride, and come back around to turn right. It's a small thing, but it's the kind of detail that only shows up once you've actually tried to get there, which is sort of the point of this whole post.
For most of the last decade, getting to Mercer Slough Nature Park meant working around something. First it was the light rail construction that closed the original park and ride in 2017 and kept crews working the site for years. Then it was the uncertainty over who was even running the boathouses after a national outdoor retailer pulled out of the rental business altogether. Neither of those things is true anymore, and if you've been skipping the slough because of what it used to take to get there, August is a good month to find out what changed.
What's Left of Blueberry Season
The U-pick rows at the Mercer Slough Blueberry Farm typically run from mid-June through mid-September, though the season shifts a little with the weather each year. Right now you're past the peak but still well inside the window. Current hours are Tuesday through Saturday, 8 a.m. to 5 p.m., and Sunday 8 a.m. to 4 p.m. Bring cash or a check. Cards aren't accepted at the stand, and the farm hands you a bucket at check-in that you fill and pay for on your way out.
If you're paddling past the farm instead of parking at it, keep an eye out along the banks. Wild blackberries grow along the Enatai stretch of the route, a bonus worth timing a summer trip around.
The Station That Used to Be a Dead End
South Bellevue Station sits directly on the park's western edge, close enough that the slough's colors were the design inspiration for the artwork on the station's guideway panels. For two years, that station was the end of the line. Preliminary 2 Line service began between South Bellevue and Redmond Technology Station in April 2024, and South Bellevue stayed the western terminus of the system until March 28, 2026, when the full Lake Washington crossing finally opened, connecting the Eastside straight through to Seattle via Mercer Island and Judkins Park.
That matters for the park more than it sounds like it should. A terminus station absorbs the turnaround traffic and the layover congestion of an entire line. A through station doesn't. The 1,500-stall garage at South Bellevue is fully open now, and Sound Transit and King County Metro have routes planned to redirect through the station later this year, including a rerouted Issaquah connection that would put South Bellevue on the way to Bellevue rather than a stop out of the way.
"People will see an opportunity to explore more of the east side of the region," Redmond Mayor Angela Birney told The Urbanist when the crossing opened.
It's a comment about regional mobility, but it applies just as well to a wetland park that most of the region drives past on I-90 without a second look.
Who's Actually Handing You a Paddle Now
The other change is quieter and easier to miss if you haven't rented a kayak here in a year or two. REI Co-op closed its Experiences division in 2025, which had run the boathouses at both Enatai Beach Park and Meydenbauer Bay Park. Best Kayak Rentals, staffed by former REI Experiences guides, took over both locations that same year and kept the walk-up model intact. No reservation needed. Rentals run seasonally, roughly May through September, and cover kayaks, canoes, and stand-up paddleboards by the hour.
One caveat worth knowing before you plan a group outing: picnic site rentals at Enatai are currently paused because of construction at the park. Walk-up boat rentals and the swim beach are unaffected, but if you were picturing a reserved picnic table as part of the day, check the city's rental page first.
Where the Water Actually Goes
The slough's canal is limited to human-powered watercraft, which keeps the water quiet in a way that's easy to forget is fifteen minutes from downtown Bellevue traffic. From the Sweyolocken Boat Launch or from Enatai, the paddle takes you past habitat for great blue herons, bald eagles, and beavers, with water lilies thick along the calmer stretches by late summer.
- Ranger-led canoe trips run Saturdays and Sundays from Memorial Day through Labor Day, 8:30 a.m. to noon, launching from Enatai Beach Park.
- Self-launch access is available year-round at Sweyolocken, no rental required if you're bringing your own boat.
- Best Kayak Rentals operates both the Enatai and Meydenbauer boathouses on the same walk-up basis, so either launch point works if you don't own gear.
On Foot, Three Trails That Don't Overlap
The park's trail system splits into distinct routes rather than one loop, which is useful to know before you park somewhere expecting a single obvious path.
The Heritage Trail runs past the blueberry fields, the old greenhouses, and the historic Winters House, a good option if you want the working-farm side of the park. The Bellefields Trail cuts through forest, wetland, and meadow terrain on the park's northern half. The paved Periphery Trail circles the whole property and connects out to the Mountains to Sound Greenway, which makes it the pick for strollers, joggers, or anyone who wants pavement instead of boardwalk. Separately, Enatai Beach Park serves as the western trailhead for the Lake to Lake Trail, a longer route that eventually reaches Lake Sammamish.
If you want a guide instead of a map, the Mercer Slough Environmental Education Center runs a free nature walk every Saturday at 2 p.m., leaving from the visitor center. The center itself is open daily, 10 a.m. to 4 p.m., but parking there is genuinely limited, around 22 spaces, so arriving early or parking at the blueberry farm or Winters House instead is the more reliable plan.

| Ranger-led canoe trips | Saturdays and Sundays, Memorial Day to Labor Day, 8:30 a.m.-noon | Enatai Beach Park |
| Free guided nature walk | Every Saturday, 2 p.m. | Mercer Slough Environmental Education Center |
What Actually Changed
None of this is new scenery. The wetland, the herons, the blueberry rows planted generations ago, all of that has been sitting in the middle of Bellevue the entire time light rail crews were digging up the park and ride next door. What changed is the two reasons people had for staying away. The station stopped being a dead end in March. The boathouses stopped being a question mark last year. If your mental map of Mercer Slough still has orange cones in it, it's worth an afternoon to update it.
Parks like this are part of what makes daily life in Bellevue what it is, and it's the kind of detail that never shows up on a listing sheet. If you're curious how a specific Bellevue or Eastside neighborhood actually lives day to day, not just what it costs, Carissa Saffel is always glad to talk it through. Reach out to schedule a consultation whenever you're ready.
