Iron Gate

Development Route / by Captain ‘O’ & Gravel Girl

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 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 to early for the bloom of spring colors.

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.

For safety, we recommend that you carry dog repellent and a have a red blinky light. The dogs we encountered seemed friendly … but got our attention.

The Dirty Freehub Team has not ridden the entire route, thus the Training Route designation. The route is an adaptation of the Upper Klamath Honey Badger route found on RideWithGPS. Note, we have mapped it in the opposite direction to that of others and added some river miles in the beginning.
