O’Leary Landslide Loop

5 Star Route

This route may have been impacted by the unprecedented and historic wildfires in Oregon during the summer of 2020. Thus, we are uncertain of the route condition and are uncertain if the route description is accurate. If you attempt the route, we would really appreciate your feedback in the comment section at the bottom of the page. 

A big climb! Beautiful views! And one of the best gravel descents in the region!  And Gravel Girl’s Favorite Ride.

After a short warm-up, the ride attacks a demanding and majestic climb of 3500 feet in 10 miles. From mile 3 to 9 the grade is always between 6 to 12 %. The ride surface varies from light chip seal to short sections of gravel, to broken tarmac. You will also have to “hike a bike” for about .25 miles across several old landslides. The higher you climb, the better the views become.

At  ~ mile 17 you leave the pavement behind. At times the gravel is course and deep, but it is mostly fine and fast. The ride rolls for several miles and then begins a nearly 10-mile descent, all on gravel, to Cougar Reservoir. At the bottom of the descent veer right ~20 yards to the boat ramp and go for a swim. Now traverse around the reservoir in a clockwise direction taking in all its beauty. Then a quick descent down to Belknap covered bridge and the McKenzie River. Your almost home!
