"Likely the most difficult ascent in Montana, the north side of Beartooth Pass is a long and specular hill climb into the rugged Beartooth Mountains of southern Montana near the border with Wyoming. The grade begins as quite shallow and gradually steepens (but is never steep) as you generally head south. Once you have gained some altitude you encounter some amazing views down into the valley as you ascend multiple switchbacks with exposure in places. Around mile 22 the climb pops out above treeline and heads across spectacular alpine terrain as you cross into the state of Wyoming. At mile 27 there is a descent before the final push up to isolated Beartooth Pass at 10,947 feet..."(This quote is presented with the approval of John Summerson, from his book, The Complete Guide to Climbing (by Bike), 2nd Edition, pg. 191.)
The altitude is more a factor than the gradient on this climb (nearly 11,000' and 33% less oxygen).  The average grade is 3.3% (4.1% climb only).  57% of the climb is at 0-5% grade and 30% at 5-10%. The steepest quarter mile is 10.2% and the steepest mile 6.6% (see Steepest Gradient tool in Gradient Tool section).

Roadway:  Excellent.  Beartooth Highway is closed during winters.  Check roadway conditions at - Beartooth Hwy.

Traffic:  Moderate and slow moving.  There will be many Harley Davidson motorcycles cruising this road leading up to the South Dakota Sturgis Motorcycle Rally, which is in the first week of August each year. 

Parking:  We parked on a side street near the start when we climbed Beartooth Pass.  See also Google Maps - Parking in Red Lodge.  You can avoid the first 7.3 miles of riding at 2% on Highway 212 by parking at the parking lot with the Custer National Forest sign:  MapStreet View.
Clothing:  This climb finishes above 10,000', which is 5,000' above the start.  Consult the PJAMM "Full Forecast" feature for the time you expect to arrive at the finish to assess what clothing to bring on your ride. 

Provisions:  This is a 60 mile out and back with no water or food along the way - plan accordingly.

This is a nice climb to do on your way to Yellowstone National Park.  We rode Beartooth Pass then drove 68 miles to the Northeast Entrance Station to Yellowstone and then another 28 to Roosevelt Lodge (Google Map + Reviews)  where we stayed before doing the Yellowstone Grand Loop the next day (Map of Route).  On the Grand Loop you pass many Yellowstone attractions, including Old Faithful and the Continental Divide. 

This climb starts in Red Lodge, MT where there are many hotel options for your stay.  If you are staying in the area for a longer visit, there are many great cabin rentals in the area too.

Spectacular ride. The views as you gain elevation are exceptional. This is a long climb however it stays around 5%. I saw 8% once. The switchbacks in the middle reminded me of Horseshoe Meadows Road, just not as steep.

I didn’t finish this ride because the wind was a bit too strong after rock creek vista but the climb I did do wasn’t steep and the road was in good condition. I finished 40 of the 60 miles starting at US forest service beartooth ranger station (I found other cyclists also park here) finishing at the rock creek vista. Although most of the ride there is very little/no shoulder the limited traffic made this okay. Highly recommend! Above I find the traffic rating a bit confusing! It was light traffic..5 makes it seems heavy

Cycling Beartooth Pass (Montana-Wyoming)

Ride 30 miles gaining 6,040’ to elevation 10,949 at 3.4% average grade.

Climb summary by PJAMM’s John Johnson.

Beartooth pass is one of the greatest bike climbs in the United States. This climb has been hailed for the past 50 years as “the most beautiful road in the United States.” The climb is in the Beartooth Mountains and Gallatin and Custer National Forests and connects Red Lodge Montana wth Cooke City and Yellowstone National Park in Wyoming.

This is a US Top 10 Most Scenic Bike Climb.

"Ascending Beartooth Pass from the north is an unequivocally stunning experience; its beauty is beyond dispute. The gradient of the climb is relatively gentle throughout, but the combination of its length, elevation gain, and altitude rightly secures its position among the Top 100 U.S. Climbs. Additionally, it is celebrated as one of the Top 10 Most Scenic U.S. Bike Climbs due to its breathtaking landscapes."  


Beartooth Pass from the north can begin in Redlands, Montana.

Population 68,747 (2017); elevation 1,358’.

The more scenic Beartooth North route begins in the charming Montana town of Red Lodge (2020 population:  2,257), at the beginning of the Beartooth Scenic Byway.  We enter Custer National Forest at mile 7.3 and begin climbing up a canyon where the roadway begins a six mile series of spectacular switchbacks  at mile 14.  


Mile 7.3 - enter Custer National Forest

Established 1908 by Teddy Roosevelt; 1,188,130 acres.

This is the alternate start spot - paved parking here.

The first 14 miles are a great warm up the next 16 miles of high altitude climbing.  This segment averages 3% and leads up to the alpine surroundings which end as we climb above tree level at mile 17 at just over 8,000’.

An alternate start point if you prefer to eliminate the first less scenic miles from Red Lodge is to start at the Custer National Forest sign at mile 7.3 where there is a public parking lot.  The first 7.3 miles from Red Lodge average 2% with 790’ of elevation gain.  We started in Red Lodge the two times we climbed Beartooth Pass and enjoyed the entire experience - at just over 30 miles, Beartooth Pass is the10th longest climb in the United States.

Scenes along the first 14 miles of the climb.

Beartooth Highway (Route 212) opened in 1936 and is generally closed due to snow all but 5-6 months of the year from around May to October.


Beginning at mile 14.4 there are 6 hairpins for 5.8 miles averaging 4.5%.

"Beartooth is ranked among the top 10 best hairpin bike climbs in the United States."

Beartooth Pass is situated in the Absaroka-Beartooth Wilderness and spans the Beartooth Mountains, which are part of the greater Rocky Mountains range. The pass crosses through the Custer and Shoshone National Forests.

The lack of trees combined with the imposing cliffs provides expansive views of the winding hairpins as we ascend. The views up towards the roadway to come, and back at the roadway already traveled are magnificent along the switchback corridor (see slideshow).  It is along this stretch that we fully appreciate being on the bike as we have none of the restrictions of motorists along this scenic route - we can stop where we please, cross the road (when safe, of course), go any speed we please and, quite simply, fully appreciate the splendor of this magnificent climb.  Words do not do justice to the climb, although we believe the photographs in the slideshow above prove our point.  

MILES 19.5 TO 26.5


Rock Creek Vista is at mile 19.5 and at the very end of the first set of Beartooth hairpins.

This climb is never “difficult” in the sense of steepness or challenging grade, but it is long and climbs to high elevation.  We had trained and were prepared for many days of back-to-back-to-back Top 100 climbs, yet Beartooth was more demanding than anticipated.  We feel it’s primarily the altitude that taxes the rider, particularly those from lower elevation venues that cannot train for altitude before tackling this climb.  The first ten miles of the full route gain only 1,165' at 2% average grade, while miles 10-26.5 pick up to 4.5% average grade, gaining  4,075' along the way.  At mile 26.5 there is a 1.3 mile -4.9% average grade descent (-350') followed by a final two miles at 3.8% (we could have gone without that 350’ ascent on the way back to Red Lodge!).  

Enter Wyoming and Leave Montana at mile 23.7.

The route itself is very simple:  Climb east on Highway 212 (Beartooth Highway) out of Red Lodge, MT  for 30 miles until you reach Beartooth Pass.  This is a very long climb - the ninth longest in the US - PJAMM Cycling Top 100 Longest US Road Bike Climbs.


There is a stark contrast from the lush forests and alpine meadows of the first half of the climb with the  jagged rock formations and snow-capped peaks surrounding us the second half of the climb.  There are several glaially formed lakes visible along the upper part of the climb.

4 fun hairpins just before the finish for 1 mile at 4.5% grade.


Over the last 3 miles we encounter a 1.5 mile 5% descent from mile 26.5 to 28 and the second set of hairpins on one of the greatest hairpin climbs in the US.


You’ll feel it at nearly 11,000’ elevation.

This is the highest paved point in

Beartooth Highway was referred to by the late CBS news correspondent Charles Kuralt as "the most beautiful drive in America” which offers the following description of the roadway:

The Beartooth Highway is a 68-mile travel corridor, beginning (at its easternmost terminus), just south of Red Lodge, Montana at an elevation of 6400 feet and ending (at its westernmost terminus) near the Northeast Entrance to Yellowstone National Park and Cooke City and Silver Gate, Montana, at an elevation of 7500 feet. In between those two elevations, the road rises to 10, 947 feet at Beartooth Pass in Wyoming. The section of the Beartooth Highway that has been awarded the National Scenic Byways “All-American Road” status is a 54 mile section of the Highway beginning 8 miles south and east of Red Lodge and ending just east of Cooke City, Montana.

Cycling Beartooth Pass North, Montana - wildflowers along the route

Our research indicates there had been a race up Beartooth from Red Lodge in recent years past, but it is unclear if it has survived - we welcome and will include any input regarding the viability of this event.  A past post for the event Beartooth Blitz notes, “The run up Beartooth Pass was recently named one of the 5 top bike climbs in the nation, the Beartooth Pass is a once-in-a-lifetime ride.”

Roadway Surface and Traffic Report:  The roadway is in excellent condition.  Traffic was fairly heavy when we climbed the pass on August 3, 2015.  We were surprised that there were many more motorcyclists (the touring, not low slung racers) than cars on Beartooth - we later learned this was related to the beginning of the annual Sturgis SD Harley Davidson week-long festival was about to begin.

Bike climb Bear Tooth Pass North - cyclist on perfect road

The roadway is in pristine condition. 

In a nutshell - if you ever have the opportunity to do this climb - DO IT!  Do not pass up the opportunity - it is a Bucket List Climb.  We loved the scenery, the altitude challenge, the spectacular views and the switchback views, particularly looking back at the roadway that we had already traveled in the far distance well below us.

Cycling Beartooth South from Cooke City

Ride 21.5 miles gaining 4,378’ at 3.6% average grade (4.7% climb only)

The Challenge:  We did the full up-over-back up-down from Red Lodge which is quite the challenge at 88 miles riding and 9,866’ of climbing.  This route tacks on the descent+ascent of Beartooth Pass South.

The descent of Beartooth Pass is one of the most enjoyable in the US.
