If you were at the north trailhead on McKenzie Highway sometime in early July, you probably noticed the new signage. Cedar Shark, it reads, and if you've spent any time on the local trail forums or overheard the after-work crowd at the parking lot, you already know the name came from a community vote and a cedar stump along the route that looks uncannily like a shark fin breaking the surface. The trail itself is stitched with what builders call "shark fin" features, berms that rise and roll straight into jumps.
What most people haven't clocked yet is that Cedar Shark isn't a trail you can ride start to finish. It's a segment, and where it currently ends matters more than where it begins.
What actually opened on July 3
Thurston Hills Natural Area got its newest addition on July 3, 2026, built by Disciples of Dirt, the volunteer mountain bike club that has been shaping this park since it first opened to the public. Lead trail builder Jack Hill and a rotating crew of club members logged more than 500 hours across a series of organized "dig days," hand-carving berms, rock gardens, and a steep chute into the hillside east of town.
The features are real and they're already drawing riders. But the trail is, in Willamalane's own words, partially complete. Cedar Shark currently connects into the lower half of Chinquapin Chutes, which is rated double black diamond, expert only. An additional lower section is planned to extend the trail further, but that piece isn't expected to open until summer 2027.
That's the part getting lost in the excitement. If you're a casual weekend rider hoping to sample the neighborhood's newest attraction, the honest answer is that right now it dead-ends into the hardest trail in the entire system. You'd need to already ride Chinquapin Chutes comfortably before Cedar Shark adds anything to your loop.
As Hill put it when the trail opened, the goal was "filling a missing piece of the Thurston Hills trail system." He's right that it fills a gap. It's just a gap most of us weren't equipped to notice, let alone ride.
The easier way in is a Tuesday night, not the trailhead
Here's where the actual opportunity sits for anyone who isn't running double black diamond lines. Disciples of Dirt hosts weekly Taco Tuesday rides at Thurston Hills through the summer, along with other group rides and volunteer opportunities. This is the accessible version of what's happening on Cedar Shark right now: you get the same crowd, the same trail talk, the same sense that something is actively being built in your own backyard, without needing to clear a chute built for experts.
It's also the more interesting story if you think about it for a second longer. The club that just spent 500-plus volunteer hours building a trail most residents can't yet use is the same group some of whose members logged nearly 100 hours apiece on trail maintenance in 2025, keeping the rest of the system rideable through the winter and ready by spring. Cedar Shark is the headline. The Tuesday rides are the actual civic infrastructure.
A park that doubled in size without most of us noticing
Here's a number that puts the whole thing in perspective. When Thurston Hills opened to the public in 2017, it had 6 miles of trail. Today it has more than 12, including five designated downhill mountain bike trails that open seasonally for dry-weather riding. That's not incremental growth. That's the trail system more than doubling in under a decade, largely on the strength of volunteer labor from a single nonprofit club and continued investment from Willamalane Park and Recreation District.
For hikers and families who have no interest in berms or jumps, none of this changes much on the ground. The Lower Mossy Maple Trail still offers a family-friendly 3-mile round trip from the north trailhead at 7575 McKenzie Highway, and the loop from Quartz Park to the foot-travel-only Cascadian Thumb Trail still climbs to the same basalt rim views over the Willamette Valley and the Cascades foothills that have been there since the land was timber ground on the old Gray family homestead. What's changed is the energy around the place. A park that used to be a quiet after-work walk now has an active build culture attached to it, visible in the fresh dirt, the new signage, and the trucks parked at the trailhead on a Tuesday evening that didn't used to be there.
The rest of the neighborhood isn't waiting on trail season
Thurston Hills is getting the attention this month, but it's not the only thing reorganizing the neighborhood's calendar. Splash at Lively Park, the indoor waterpark at 6100 Thurston Road, keeps its wave pool running at a steady 86 degrees through the summer, and this Friday, August 28, the usual 4:30 to 7:30 p.m. waterpark swim is replaced by a Dive-in Movie night. A bigger shift is coming soon after: Willamalane Park Swim Center is closing for maintenance, and Splash will pick up expanded hours to cover the gap, with the full schedule set to post in the last week of August.
A few miles away, the neighborhood's food scene has quietly turned over too. Cajun Claws Seafood Boil House took over the long-vacant former Shari's near Pioneer Plaza in late May, serving a choose-your-own seafood boil with corn, sausage, and beignets from 11 a.m. to 9 p.m. daily at 1807 Pioneer Parkway East. And if Sunday mornings used to mean driving into Eugene for produce, that's no longer necessary. The Lane County Farmers Market launched a dedicated Springfield Farmers Market on June 7, running Sundays from 9 a.m. to 2 p.m. through October in the Springfield Public Library parking lot on Fifth Street, with close to 50 vendors selling everything from flowers to ready-to-eat food.
None of these things are connected to each other in any official sense. But taken together, they describe a neighborhood where the default weekend routine looks different than it did a year ago. A Tuesday ride at Thurston Hills, a Sunday morning at the farmers market, a seafood boil that didn't exist five months ago. That's a more accurate picture of what's actually happening here than any single headline about a new trail.
What this means if you already live here
The obvious story about Cedar Shark is that Thurston Hills got better. That's true, but it undersells what actually happened. A volunteer club put in more hours than most people will spend on their own yard projects this year to build something that, for now, only benefits the smallest slice of riders in the park. The bigger win for everyone else is what that same club does every Tuesday night, and what it's already built over the past several years to take the trail system from 6 miles to 12.
If you're the kind of resident who reads local trail chatter and wonders whether to bother driving out to McKenzie Highway this week, the honest answer is: go for the Tuesday ride, the farmers market, or the pool night before you go looking for Cedar Shark itself. The shark-fin stump will still be there next summer, and by then the trail might actually connect to something you can ride start to finish.
