Osberg Ridge is a sublime ribbon of alpine single track. Summiting at just under 3000m (9800ft), Osberg masterfully follows the mountain contours to twist and turn through meadows, burned forest and past rock faces to offer views at nearly every pedal stroke. While best, and most popularly, travelled from west to east, this trail can be ridden in both directions. Expect to be sucking air before enjoying the fast and flowy downhill.

      Dry and dusty for most of the trail. Was smoky when I rode it, but still a bunch of fun.

       We accessed it via Adam's Gulch (a.k.a. Adam's Rib) which was a tough double black climb up. We dropped down Castle Creek (see my note on the Castle Creek segment) to Warm Springs Road. Would recommend accessing from Baker Creek road, start and finish. It was in great condition and very beautiful. Lots of big open slopes of blue and yellow lupine (this was a very heavy snowfall winter). Still some snow up top. Great trail.

       Thanks for posting! Just to be clear, do you recommend accessing the Osberg Ridge trail from what is marked as the "finish" on this page and possibly ending via Curly's trail? Dumping you near the beginning of Baker Creek rd. This would mean riding the Osberg Ridge trail in the opposite direction than you did. I guess what I am asking is do you think riding Osberg in the reverse direction would be fun/doable? Thanks for any advice.

       Follow up to my question above. Yes, riding the Osberg Ridge Trail in the reverse direction to what is posted here is super fun! I rode this trail 7/22/17. We ended up shuttling and got dropped off at the end of Baker Creek Road. Though spinning the road was pretty common, judging by the number of people we passed. The climb out of the creek is beautiful, and contains some punchy stuff characteristic of the area, but is generally pleasant. Nearly the entire ride is in a burn, and the wild flowers have really made the best of it! The initial climb was about 45min and then you get into some more traversing terrain before the last decent climb topping out around 9500ft. From there there is a lot of traversing and down. We got a bit confused and ended up on a detour via the Osberg-Adams connector to the Fox Peak Connector which was nice too and dumped us back into Osberg Ridge Trail. We ended up finishing on the Oregon Gulch Trail which was a blast! Highly recommend, with a few caveats. The last mile+ before the Oregon Gulch Trail was 2-track and pretty hot and boring. Then the first bit of Oregon is UP and LOOSE. But it quickly changes over to fast and DOWN! We spun into town, I'm guessing 6 miles or so to finish with a beer.

       Gorgeous trail. Not obvious when EBaker ends and Osberg’s begins, but it doesn’t matter. Following the trail will naturally route you on the counterclockwise fork around Fox peak as well. Did this w a buddy who was on a gravel bike, and he raves about it. Cut out half way to descend Alden gulch, but next time would prefer to ride the entire ridge. Next year!
