"The most difficult climb in Wyoming, the ascent of giant Alternate 14 starts out on a shallow, steady grade. For the first few miles the road is very straight and you can clearly see your objective ahead. After 6.4 miles the grade increases as you start to clearly see your objective ahead. After 6.4 miles the grade increases as you start to switchback up the hill. Eventually the road clings to the side of a cliff with great views. After entering a gorge, the grade eases, there is a small descent, climbing resumes and then the climb ends (unmarked) at a brake check area for cars which is on your left as you ascend. After a small descent the road continues to gain in elevation but significant climbing has ended..." (This quote presented with the approval of John Summerson from The Complete Guide to Climbing (by Bike), 2nd Edition, p 234.)
Average grade is 6.7% (7.8% with descent eliminated from the gradient equation).  The grade ranges wildly on this one:  10.5% (1.4 miles) is descent;  23% (3.1 miles) is in the 0-5% range; 42.5% (5.6 miles) 5-10%; 20% (2.7 miles) 10-15%; 2.6% (.miles) 15-20% and 1% is at ≥ 20%. Steepest quarter mile is 14.1% and steepest mile 11.3%.

Roadway:  Two lane highway in excellent condition with a shoulder to ride in as needed. 

Traffic:  Mile to moderate with a lot of big rigs going over the pass - this is not a climb (at least for the first few miles before the big right turn at mile 4.2) for for the traffic averse.  Traffic does not seem as much as problem as we begin to climb up the mountain higher and higher. 

Parking:  Not a problem in these parts - park off the side of the road on the side of the unnamed dirt road at climb start - Map;  Street View. 
Provisions:  None on the route.  Closest are in Lovell 18 miles west. 

Weather and Gear:  You finish this climb just over 9,000', nearly 5,000' above where you 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.

This climb was harder than expected. Rode Onion Valley and Horseshoe Meadows Rd last month but I think this was the longest section of sustained 10-11% I have climbed. The start is from a mining access road. Lots of truck traffic there but it won't affect your ride. There is a shoulder for the first 3.7 miles however the rumble strip takes up part of it so it was not always possible to be out of the lane. 5 to 6 miles in the road gets rough from damage and repaving.. However after 6 miles there was brand new pavement all the to the top. There is no water but there are some streams I was willing to try. We ride it with two large water bottles and had plenty of water.. This is a remote ride and like most climbs the beautiful parts are in the last few miles. If you have a reason to get in this area I recommend it.

Cycling Alternate Route 14, Wyoming - sign for 10% grade next 13 miles

Cycling Alternate Route 14, Wyoming.  

Ride 13.2 miles gaining 4,840’ at 6.7% average grade (8.4% climb only).

This challenging ascent is ranked as the twenty-first most difficult bike climb in the United States, leading riders into the Bighorn Mountains from the Bighorn Basin.

The Alternate Route 14 climb is the hardest road cycling climb in Wyoming.

Alternate U.S. 14 runs east-west across northern Wyoming.  This bike climb is exceptionally scenic, yet one of the more remote Top 100 U.S. Cycling Climbs.  This is the only signed alternate route in Wyoming and is just 65 miles from the start of the other Top 100 Climb in Wyoming (Granite Pass, #58).   The distant views to the south of Wyoming's northern plains and mesa formations are phenomenal.  These exceptional views are to our right as we climb out of the “flatlands” (keeping in mind we start the climb at 3,745’) and are with us for at least half the climb until the brutal grade softens a bit as we enter the last segment consisting of rolling hills and grasslands.  


View at the start of the climb.

We chose to begin our climb adjacent to a gravel mining/quarry road, as this location not only reduces the distance traveled on highway straightaways but also offers convenient parking and stunning views. At the 1.7-mile mark, the road inclines sharply, significantly slowing down any trucks beyond this point.

This is one of many gravel roads that we would have loved to have explored had we brought a gravel bike or 30mm tires.  There are many gravel roads off Alternate Route 14 that are open range and seem available to ride with the proper tires and bike.

Old US 14A is another gravel opportunity at mile 4.3

 Highway 14A is also known as the Medicine Wheel Passage Scenic Byway, formerly Dayton-Kane Highway.

The first mile up the giant hairpin averages 9.2%.

We leave the Bighorn Plains far below us as we cycle up Alternate Route 14.

There’s no doubt about the steepness of this climb.  Along the way, we encounter (a) 2 runaway truck ramps, (b) 2 brake check/brake cooling points and (c) several % grade and use low gear signs.

We enter Bighorn National Forest just after mile 7 although the monument is at Crystal Creek Overlook at mile 9.8) .  This is one of the oldest forests in the US (established 1897) and consists of 1,107,571 acres. Bald Mountain Campground is a few miles past the summit.

There are great views of Bighorn Basin from this overlook. 


The final 3 ½ miles average 8.3% with one brief descent around mile 12.2 and a fairly flat final 150 yards.

This is not a “pass,” neither on the map nor by definition, as the east side does not drop off but rather continues eastward but not downward from the peak elevation on the west side of the climb (no out-and-back here; 10 miles past our stop point we are still above 9,000’ elevation).  

Traffic and Roadway Surface Report:  The roadway is in good shape, in spite of the several “Road Damage” signs we encountered in August 2015 and September 2023 along the brutally steep section of the climb – it appears roadway repair had been completed, but the signs not removed.  Traffic can be quite disconcerting until about five miles in -- essentially all of the big rigs that seemingly “fly by” over the first five miles turn onto a dirt road that by our review appear to lead to a couple of quarries (born out by the sign at the beginning of the turnoff which includes several warnings not encountered on normal rides – e.g., “Heavy Truck Haulage,”  “Explosives in Use,” “Warning Signal: Prior to Blast Short Audible Horn Sounds,” etc.).  Traffic from mile 5 to the top is mild.

Cycling Alternate Route 14, Wyoming - cyclist riding on straight stretch of roadway

In a nutshell:  This is an incredibly scenic climb that is highly recommended and can comfortably be included in a Yellowstone/Beartooth Pass/Chief Joseph/Granite Pass trip.  Highway 14 Alternate Route bike climb begins 59 miles from Cody, Wyoming (the start of the Chief Joseph Highway/WY Highway 296 climb), 84 miles from Red Lodge (the start of Beartooth Pass North), 134 miles from the beginning of Beartooth Pass South, and 178 miles from the northeasternmost Yellowstone National Park Lodge (Roosevelt Lodge).


The out and back from Granite-Alternate 14 or Alternate 14-Granite is an epic adventure with stunning scenery and great challenge at 123 mile ant 14,000’ of climbing.  Beware there is no support along this route  a except the Bear Lodge Resort, if it is open - check in advance.

  • Elite ultra runner Gary Gellin describes the ride: “It's pretty epic, John. A very long ramp to the base of the climb followed by endless sections of 10%. Great views of the Bighorn Valley if you stop to take a breath.”
  • Mark Seedall of Oakland, California describes the ride: “I found this climb rather difficult. The bottom from Bighorn Lake is quite exposed and there are strong winds in this area. Once you get to the meat of the climb, it certainly does impress. It has a 10%+ grade section for about 10 miles as I recall. A local bike shop owner in this area told me it was 12% for 12 miles. As I recall once you pull up out of the Bighorn lake you can look up and see a road that is just carved out and steep up the side of the mountain and you really have to wonder at that point what you have got yourself into. Luckily there is a flatter spot just before this very long steep pitch. The steep hard pitch goes for a long time and I was riding slowly just trying to survive. I think just about everyone in our group was feeling this way. We rode this climb on day seven of a 1,000 mile ride in Wyoming. Once to the top of the steep section, the road flattens out some, but you still have a ways to go to the real top. But the upper portions of the climb are really nice, above the treeline with views in all directions. Very isolated. The drop off from the top is very long and stays well above 8,000 feet for many miles to the intersection of Highway 14. There is no water or anything until you get to the intersection of Highway 14 -- probably 50 miles from Bighorn Lake. So, this is a very remote area and there is not much traffic. I am not sure how I would rank it in terms of climbs and all. I know that fresh legs would have made it a touch easier and likely more enjoyable. The climb the next day up the other side out of Buffalo was much better for me as it was far less steep.”
