"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

This is a US Top 10 Most Scenic Bike Climb.

This is an absolutely gorgeous climb - there is no room for debate about this.  The climb throughout is fairly mild and it is the length, elevation gain and altitude that puts the climb legitimately in the Top 100 U.S. Climbs - it would be in the Top 25 Most Scenic Climbs if we were to create such a list.  

Climbing Bear Tooth Pass North by bike - start of climb - roadway sign

Beartooth Pass from the north begins in Redlands, Montana.

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

We enter Custer National Forest at mile 4.8 and begin climbing up a canyon where the roadway begins a six mile series of spectacular switchbacks (see slideshow) at mile 14.

Mile 7.3 - Custer National Forest

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

This is the alternate start spot - paved parking here.

The more scenic Beartooth North route begins eight miles from Red Lodge at the beginning of the Beartooth Scenic Byway.  At this location, there is a public parking lot where you can park your car and begin our climb, thus eliminating 7.3 miles from Red Lodge that gain you only 790’ at 2% (dropping the FIETS index only a bit from 7.80 to 7.62).  Here is a link to the RideWithGPS map for this alternate climb route.

Beartooth Pass is, not surprisingly, in the Beartooth Mountains of south central Montana and northwest Wyoming.

Exceptional views as we climb towards the switchbacks.

Bicycle ride up Bear Tooth Pass North - roadway far below

Very few trees - minimal visual obstructions of the surrounding views.

Seven giant hairpins for six miles from mile 14.3 to 20.2

The hairpin section is 6 miles at 4.5% from elevation 7,900’ to 9,300’ at 4.5%.

The views up towards the roadway to come, and back at the roadway already travelled 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.

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!).

Montana and Wyoming state lines

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.  

Cycling to summit of Bear Tooth Pass North - Cyclists with bike at pass and and elevation sign.


Beartooth Highway is the highest paved highway in the northern Rocky Mountains and 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.

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, although we are very partial to these, the switchback views, particularly looking back at the roadway that we had already travelled in the far distance well below us (representative photograph).

The Challenge:  We have mapped and recommend for anyone interested in: (a) a significant climbing day/challenge, and (b) expanding the spectacular experience of Beartooth Pass North - the following out-and-back ride from the beginning of Beartooth Scenic Highway North to the start of Beartooth Highway Climb South and back which involved 88 miles riding and 9,866’ of climbing (Map).
