Hello, Following our trip on the Great Divide Mountain Bike Route this summer, we’re sharing our experience in this travel journal. We’re Richard and Bernadette, both 64 years old, and we’re gravel bike-packing cyclists. We’ve completed several gravel bike trips in France and neighboring countries, and Richard has also done some in South America. We left on July 22, 2026, from Geneva to Calgary via Frankfurt with our bikes carefully packed in boxes, and we returned on October 8 from El Paso to Geneva via Chicago and Frankfurt.

The GDMBR is a mountain route that closely follows the Pacific/Atlantic continental divide, starting in Banff, Canada, and ending at the Mexican border in Antelope Wells, New Mexico. This crossing of the American West is one of the longest mountain biking routes in the world, winding through wild valleys, mountain ranges, and desert plateaus. It stretches about 4,400 km with a total elevation gain of around 60,000 m. The average altitude is 2,000 m, and the highest point reaches 3,600 m. The route is 80% off-pavement (gravel roads, dirt, and a few trail segments). It’s also known for the annual Tour Divide race, which brings together the best riders in the discipline every June and follows roughly the same route.

We prepared for this trip over several months, using a few websites and an older guidebook (the 2013 English edition).



With this, we were able to organize our journey with as much information as possible, a GPS track, and gear suited to the weather conditions, terrain, and sparse resupply points in remote areas.

Once we arrived in Banff, we picked up bear spray to handle a particular challenge: the wildlife we weren’t familiar with.



After landing in Calgary, we assembled and equipped our bikes at the airport. That first evening, we were welcomed by Mike, who invited us to his place when we were looking for a spot to pitch our tent. Then we made our way to Banff over two days, taking a fairly quiet road to Canmore and then a bike path.



A visit to Banff, a charming tourist town in the national park. Its famous Fairmont Hotel.



The starting point of the GDMBR at the arch of this hotel complex.



Here we are, immersed in the wilderness—just a few pedal strokes away from the town, the contrast is striking. Powerful rivers, vast landscapes, and our first encounter with a mule deer.



Spray Lake, our first basic campsite: no showers, dry toilets, no water fountain—we filter lake water. Most GDMBR campsites are like this.





We took the west side of the lake—a longer and wilder route. A few fallen trees blocked the path, forcing us to carry our bikes. But the stunning landscapes made it all worth it!



Our first single track through a forest marked by past wildfires.





Most campgrounds have tables and metal fire rings for safe campfires, which makes setting up camp much easier—especially nice after a long, tiring day! During this trip, we mostly slept in our tent, either in established campgrounds or wild bivouacs.

We're leaving Alberta to enter British Columbia via Elk Pass.

Here are our rides, P'tit Vélo and Tori, two old 26-inch mountain bikes, refurbished (new chain, tires, brakes, etc.) and equipped with waterproof panniers. They weigh 25 and 35 kg when loaded (food, water, etc.). Less efficient than current bikes, they’re reliable and simple, easy to repair if something breaks down. Blue Lake, just before Elkford.

Sparwood and its Titan, the largest truck in the world at the time, now on display in this mining town (coal).

Fernie and its red-brick buildings. Morning encounter with a deer.

Climbing toward Harvey Pass, pretty dusty when logging trucks pass by.

We feel so small in these vast landscapes... Our cabin in Canada... We love this log shelter in bear country. We’ll sleep peacefully. Good night, little ones!

A very wild stage to reach Ram-Wigwam Recreation Site via Cabin Pass. The descent had rough pavement and a steep slope that was tough to ride. A deer joined us at our table. We met and chatted with our neighbors, who were fishing for trout.

Hello!

If you’ve completed this entire route by bike, I’ve got to say—bravo, and even a big bravo! Even at your age, I never could’ve taken on such an adventure. I’ve got to admit, I’ve never been much of a cycling fan!

I’ll be following your journey with pleasure, to keep discovering this America I love so much through your eyes. Best regards. 😊

Hi there, What an incredible adventure—hats off! It’s hard for me to imagine, since I’ve never ridden longer than a week on the road, and even then, mostly on rough trails in our Massif Central, with a gîte to stay in every night. 😕 Just a quick question: Are those log cabins you stayed in something you can rent in Canada? Do you have to go through an agency? I’d love to know how you handled your bivouacs—always at campgrounds? No need to book in advance?

And we're off... Thanks for your messages!

The campgrounds are unsupervised campsites, usually located near water (lake, stream, river, spring) which you need to filter. Each site often has a table, a spot for a campfire, and a "bear box" to protect food from those hungry bears; don’t keep anything scented in your tent for safety. There are dry toilets on the grounds. Most campgrounds are free; some are paid (you slip your contribution in an envelope into a box at the site entrance). No reservations, first come, first served. The log cabin is open access on the same principle; it was mentioned in our guide. From Wigwam, we reached a very tough and wild pass, Galton Pass, after tackling the famous GDMBR section "the wall"—a very steep, narrow, slippery path full of roots where you have to lighten your bikes and carry them. Entering the USA. We each had an ESTA ($40 per person); at the border, we each had to pay an additional $30.

Near Red Meadow Lake. Start of the descent toward Whitefish.

Freight trains run a lot in the USA, especially at night. We were surprised by their length and load: we saw one with eight locomotives spread at the front, middle, and back to pull 268 cars, each loaded with two stacked containers! We took the time to count them—we were that impressed. Between Whitefish and Bigfork, rural landscape, ranches dot the road across these plateaus.

Bigfork, on the shores of Flathead Lake.

Campsite with riders and their horses. Big pickups towing very long trailers, some shared between living space and horse vans.

"Hey bear!" "The grizzliest place in North America," they said. Here’s the only one we came across on our route!!

Descent via a single track toward Seeley Lake through forests ravaged by wildfires.

Passing through Ovando, a really charming typical village. Sometimes it feels like we're in a movie set...



Rolling plains, herds of black cows, horses in huge enclosures, irrigated meadows for haymaking—the landscape has changed.



Black bear or grizzly? We find fresh tracks along our route but no bears in sight so far. They’ve definitely spotted us, though...

Four kilometers of brutal uphill pushing our bikes over rocks led us to a pass near Stemple Pass, where we could switch to a beautiful, long descent in the setting sun...

...and arrive at Llama Ranch. The owners offer cozy cabins for passing cyclists and hikers. We didn’t meet our hosts—they were away. They don’t want money but hope every visitor will pay it forward by spreading this generosity in their own future encounters.

A night indoors now and then does wonders! So much kindness along the way: coolers filled with water bottles, sometimes cookies... There’s a real sense of respect and camaraderie here. Everyone respects each other’s belongings—no need to lock everything up. Drivers wave and sometimes stop to check if we’re okay. Passersby wish us a good trip, "God bless you."

Another tough stretch of about four kilometers before Priest Pass, then downhill to Helena. Helena is the capital of Montana. Along with Butte, these are the two major towns on the entire GDMBR. In sparsely populated Montana, the only crowds we encounter are these herds of black cows!

And another rocky descent—so much fun... on foot!! Preceded by a long sandy climb, ruts, and logs to cross: hike-a-bike. ...

Is the GDMBR mostly "gravel"? Are there still some sections of tarmac?

Arrival in Basin, a picturesque little town. Spent the night at the community center for $20. The town makes this communal space available to passing cyclists. You can take a shower at Judy’s place—she welcomes travelers.

The community center.

We continue our journey to Butte, the largest town we’ll pass through on the GDMBR.

Butte developed starting in 1880 with the exploitation of its copper mine. Spent the night at a comfortable campground like the ones we know in Europe (34 € per night). We even found gas cartridges at the front desk!

At Wise River, we had to change our route: wildfires forced a detour because the road was closed. We continued on the road through Wisdom and Jackson. Disappointed to leave our planned route because the passage through Elkhorn Hot Springs was described as a stunning road.



In the end, it was a great surprise even though we added thirty kilometers to the odometer: we followed the Big Hole River, and the landscapes were magnificent. The weather turned bad, with a strong headwind. Desert-like landscape with lots of sagebrush. We shared part of the route with the TransAmerica Trail—it’s the very first transcontinental bike route in the U.S., stretching 6,800 kilometers, created in 1976. We met a few cyclists crossing from east to west, from Yorktown (Virginia) to Astoria (Oregon).

And we arrived in Bannack just in time to take shelter from the storm rolling in...

Visite de Bannack. Cette ville, fondée en 1862 sur l'emplacement d'une importante mine d'or fut la première capitale du Montana.

Actuellement, ville abandonnée de la ruée vers l'or, Bannack est transformée en musée à ciel ouvert.

Trois jours où nous avons joué avec l'orage l'après-midi. Nous avons rencontré des gens amicaux qui nous ont aidé à trouver des abris. Nous avons traversé de grandes vallées et un immense plateau désertique à 2500m d'altitude puis un très long canyon magnifique pour arriver à Lima.

Un vrai plaisir ces étapes roulantes même si elles nous font faire pas mal de dénivelé chaque jour.

Un cattle guard comme nous en avons franchi des centaines au fil du voyage...

Bon appétit ! Nous nous sommes régalés avec le beef-jerky (viande de boeuf maigre tranchée et séchée), le pepper jack (fromage relevé par l'ajout de piments), les cookies généreux en chocolat noir ...

Upper Lake. Couchant magnifique sur le lac avec canards, cygnes trompettes et autres oiseaux de ce refuge de vie lacustre sauvage...

Pronghorns. Ce sont les antilopes d'Amérique du Nord qui vivent dans les grandes prairies et les zones désertiques. Elles se déplacent en troupeaux et sont farouches.

Au revoir Montana ! Nous rentrons dans l'Idaho après le Red Rock Pass.

Passage rapide dans l'Idaho, le temps de traverser un plateau très agricole (blé et pommes de terre) en pleine moisson, très efficaces avec leurs matériels d'une autre dimension.

... Le temps aussi de voir notre premier ours noir traverser devant nous; il n'a pas attendu la photo pour se sauver !!

Nous voilà dans le Wyoming, au terme de 2000 kilomètres. Nous longeons le parc de Yellowstone et rentrons dans le parc du Grand Teton.

Un petit air de Far West. Dans la montée du Togwotee Pass (2909 m).

Après avoir passé une soirée avec une famille américaine qui nous a gentiment invités à partager le repas avec eux autour d'un feu de camp, nous attaquons la montée du Union Pass (2810 m). Aïe, premier souci mécanique: le corps de la roue libre du vélo de Bernadette casse et elle pédale dans le vide. Nous faisons du stop, un pick-up s'arrête et embarque le vélo et la cycliste jusqu'au refuge de Stawberry Creek à bonne distance après le col. Richard continue à vélo et nous nous retrouvons dans cette cabane pour la soirée que nous partageons avec un couple d'Irlandais qui parcourt également la GDMBR.



Le lendemain, nous échangeons nos vélos; Richard transforme le vélo en panne en Fixie en attachant la roue libre aux rayons pour continuer à avancer. Il gère au mieux ce bricolage mais il perd les pédales dans une descente et finit par se prendre une bonne gamelle !! Heureusement il peut repartir et quelques kilomètres plus loin, nous voyons le seul véhicule de la matinée: c'est une cow-girl qui descend à Pinedale avec son pick-up. Elle nous aide avec un grand sourire, embarque le vélo et Bernadette. Tout en roulant, nous aurons un échange très intéressant sur son métier, la vie dans ce milieu semi-désertique, et son activité d'hiver sur l'artisanat du cuir... Merci Brittany ! Richard reprend son vélo et repart sur l'itinéraire...

Avec élan, il me rejoint 70 kilomètres plus loin, dans l'après-midi, à Pinedale.

Le jour suivant, avec l'aide d'un garagiste-auto qui nous prête gracieusement quelques outils qui nous faisaient défaut, Richard remplace la pièce défectueuse sous le regard du mécanicien Logan très intéressé par cette mécanique qu'il ne connait pas. Nous avions une pièce de rechange dans les sacoches ainsi que d'autre matériel et pièces de dépannage.

Quelques dernières fermes et c'est le début du désert du Great Divide Basin qui se termine à Rawlins, 220 miles plus loin...
