Iron Gate

Development Route

Note: This is a Development Route, meaning that it is a work in progress and currently does not meet the Dirty Freehub 5 Star standard for great routes.

This route deserves further exploration! We only had a chance to ride a portion of it, but what we did ride left us wanting more.

The route features rolling hills, long stretches along the Klamath river and a circumnavigation of Iron Gate reservoir and Copco lake. We recommend that you take the time to stop at the information kiosks and learn about the history of the river and the associated dams.

The crux of the ride is series of stair steps that gain 1300 feet over 9 miles, starting at mile 10. All on gravel.

The views along this route have the potential to change radically over the next few years as several dams along the Upper Klamath river are removed including those that establish Iron Gate reservoir and Copco lake.

The Dirty Freehub Team has not ridden this route, thus the Development Route designation.

Terrain & Technical Riding Difficulty[what this means]


This is a best guess based on the sections we rode.

When we like to ride this …

The route has the potential to “go” almost anytime of the year. Our exploration ride took place in early March. The Klamath river had a roaring, beautiful flow. But … we were too early for the bloom of spring colors.

The Start

The Randolph E. Collier Rest Area along Interstate 5. Flush toilets. Water.
Lat / Long:  41.853478, -122.572609
