Make your way through Duthie Hill Park and you’d better keep an ear out for rattling chains, spinning spokes or a yell of “On your right.”

Cycling enthusiasts with the Evergreen Mountain Bike Alliance have made the park, located between Fall City and Sammamish, their own.

With funding from King County, Alliance members created a 120-acre mountain bike park for riders of all experience levels.

“This will be a jewel for King County,” said Glenn Glover, interim executive director of Evergreen Mountain Bike Alliance.

The bike park’s first phase includes a 600-foot boardwalk leading into the biking trails, a 450-foot log ride, four cross-country cloverleafs and a number of free-ride and downhill lines with mandatory jumps and drops. That first phase cost about $235,000.

King County provided $200,000 in two different grants, while Evergreen also brought in funding of about $30,000 in outside money and provided more than 6,000 hours of labor equaling to more than $90,000.

A second phase will build more trails, features and fun elements.

“Features are anything along the trail that’s more interesting then just a dirt path,” Glover said.

But as elements are added, Mike Westra, project manager for Duthie Hill Moutain Bike Park, emphasized that this trail should not scare the average or novice biker.

“People shouldn’t be intimidated,” he said. “There’s something for everybody here. We have cross country for absolute beginners and kids and they love it. It’s still fun for experts, as well. There’s also little jumps and practice features for people who want to go airborne and want to start small and work themselves up.”

Not officially open, King County and Evergreen are building boundaries but not trying to take the fun out, so they’ve allowed people to get on the trails and ride as soon as possible.

A grand opening for the park is Saturday, May 22. That event is expected to include a ribbon cutting ceremony with King County Executive Dow Constantine, vendor tents throughout the park, food and drink, raffles and activities for adults and children.

The entire bike trail will be complete within a year.

With usage off the charts, Westra said the park is drawing far more than he expected.

“As you can see, people are out everywhere,” Glover added. “They like the opportunity to progress and they like the challenges.”

Duthie Hill Mountain Bike Park is located at 27101 S.E. Duthie Hill Rd., Issaquah.
