3669 Gravel Watersheds & Pipelines

An irreversible mixed-terrain loop (⅓ unpaved) that visits the Cedar River Watershed, the Redmond Watershed Preserve, and the Tolt-Pipeline Trail. Also featuring Raging River State Forest, Snoqualmie Valley Trail, and Tolt-MacDonald Park/Ames Lake Forest.

⚠️ CAUTION! In addition to natural obstacles and features, this route also has water bars, which can be especially dangerous for bicycles!

The ride starts in Woodinville and heads to Issaquah along the Sammamish River and the west side of Sammamish Lake, continuing on to Hobart through the Squak-Tiger Mountains Corridor.

The climbing starts by heading inland through the Cedar River Watershed on a smooth gravel road, connecting to the rugged Raging River State Forest, skirting the foothills of Taylor & Rattlesnake Mountains to eventually end up in Snoqualmie.

Enjoy a brief fast descent down to Snoqualmie River with a breathtaking view of Mount Si, followed by a long gradual descent downstream to Carnation on the gravel Snoqualmie Valley Trail.

The beautiful Tolt-MacDonald Park/Ames Lake Forest provides a shortcut climb out of the valley.

A few rolling hills of pavement to Redmond Ridge rewards you with miles of soft-surface trails through the Redmond Watershed Preserve, which connects you to the Tolt Pipeline Trail for a gravel finale back to Sammamish River.

Active logging in Ames Lake Forest as of October 2019. Not recommended on weekdays until it's confirmed that the operation is completed.
