This is an amazing adventure! Did the whole loop (Baker Creek, Osberg Ridge and finished on Alden Gulch) on a perfect day which was cool, breezy with some rain the night before. When I ride with my wife, she always stops to take pictures of flowers, today, and for the first time - I did too, pretty amazing. The burned out forest next to the bright flowers was pretty spectacular and the riding was excellent. A lot of good trailbuilding on display here! Highly recommend, Alden Gulch wasn't very black, I'd say the whole thing is blue, the climbs and overall elevation did zap our strength pretty good.

Super fun trail! Very flowy but also has a remote backcountry feel to it. I donated some $$$ to the WRTC after riding it.

Trail is running great. Super fast and flowy, but don’t expect bike park grooming. Shuttled up baker rd. Road Osberg ridge to Alden gulch, which was excellent. Nice backcountry riding and gorgeous wild flowers. High point around 9500, then a fast decent to Alden gulch.
Also recommend adding on Curlys, if you have a shuttle or don’t mind 5 miles of road to get there.

The trail was in kinda rough shape, but still a lot of fun. Was not expecting how big the loop really is. Definitely make sure to pack 2-3 energy bars and a decent amount of water. I'd probably shuttle this when the access road isn't closed.

Between all the riders and the sheep, this trail is really beat up. Too bad.

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!

Rather beaten up as of July 2020. Not so flowy. Be ready for some steep switchbacks and some fairly rocky sections.

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.

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.

Osberg Ridge Trail

Hero dirt. This Ridgeline trail is soooo good. Maybe a Downed tree or 2, but not worth mentioning in my book, but honestly, it's in a burn area so one should expect that will happen regularly.

Hero dirt. Maybe the best public lands trail in Idaho. This is incredible, kudos to the trail crew who maintains this and built it!!! Again, this is in a burn area, so trees will come down regularly throughout the year...
