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?
RI RIC73 ·
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?
RI RIC73 ·
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...

Visit to Bannack. This town, founded in 1862 on the site of a major gold mine, was the first capital of Montana.

Today, the abandoned gold-rush town of Bannack has been turned into an open-air museum.

Three days where we played tag with the storm in the afternoons. We met friendly people who helped us find shelter. We crossed vast valleys and a huge desert plateau at 2,500 meters (8,200 feet) above sea level, then a very long and stunning canyon to reach Lima.

A real treat, these rolling stages, even if they make us tackle quite a bit of elevation gain each day.

A cattle guard like the hundreds we crossed throughout our trip...

Bon appétit! We feasted on beef jerky (lean beef sliced and dried), pepper jack (cheese spiced up with chili peppers), and generous chocolate cookies...

Upper Lake. A gorgeous sunset over the lake with ducks, trumpeter swans, and other birds in this wild lakeside refuge...

Pronghorns. These are North America's antelopes that live in the vast prairies and desert areas. They move in herds and are quite skittish.

Goodbye, Montana! We're entering Idaho after the Red Rock Pass.

A quick pass through Idaho, just long enough to cross a very agricultural plateau (wheat and potatoes) in the middle of harvest season—super efficient with their massive equipment.

... We also had time to see our first black bear cross right in front of us—it didn’t wait around for a photo before taking off!!

Here we are in Wyoming, after 2,000 kilometers. We’re skirting Yellowstone Park and entering Grand Teton National Park.

A little touch of the Wild West. Climbing Togwotee Pass (2,909 m).

After spending an evening with an American family who kindly invited us to share a meal around a campfire, we tackle the climb up Union Pass (2,810 m). Ouch, first mechanical issue: Bernadette’s bike’s freehub body breaks, and she’s pedaling in the air. We hitch a ride—a pickup stops and loads up the bike and cyclist, taking them to the Strawberry Creek shelter, a good distance past the pass. Richard keeps biking, and we all meet up in this cabin for the evening, which we share with an Irish couple also riding the GDMBR.



The next day, we swap bikes; Richard turns the broken one into a fixie by attaching the freehub to the spokes to keep moving. He manages the makeshift repair as best he can, but he loses the pedals on a descent and ends up taking a good tumble!! Luckily, he can keep going, and a few kilometers later, we spot the only vehicle of the morning: a cowgirl heading to Pinedale with her pickup. She helps us with a big smile, loads up the bike and Bernadette. While driving, we have a really interesting chat about her job, life in this semi-desert area, and her winter work in leather crafting... Thanks, Brittany! Richard takes his bike back and sets off on the route again...

With some momentum, he catches up with me 70 kilometers later in the afternoon, in Pinedale.

The next day, with the help of a car mechanic who kindly lends us some tools we were missing, Richard replaces the faulty part under the watchful eye of Logan, the mechanic, who’s really interested in this bike mechanics he’s not familiar with. We had a spare part in our panniers, along with other repair gear and tools.

A few last farms, and then the start of the Great Divide Basin desert, which ends 220 miles later in Rawlins...

This is exactly the kind of trip that dreams are made of, but unfortunately, I won’t be able to do it anymore. Too physical, and especially not enough bike experience. (Handling breakdowns, specific mechanics) I’ve never set foot in the American West, but those two states—Montana and Wyoming—have always drawn me in, even though I don’t know why.

Le Great Basin est un désert où aucune eau de pluie ne s'écoule dans un océan. Nous traversons ce vaste espace de 350 kilomètres, inhabité et désertique , en cinq étapes. De belles lumières ... Pas un véhicule en 200 kilomètres... Sol variable de la piste facile bien compactée, au terrain pierreux malaisé, parfois tôlé ou dans le sable. Les cyclistes et les vélos sont mis à rude épreuve.

Après une nuit à South Pass City, nous arrivons à Atlantic City, villes minières . La ville a décliné après la fin de la ruée vers l'or vers 1870.



La ville a préservé un fameux saloon connu pour ses burgers. Mais il était fermé lors de notre passage.

Chance, à côté un restaurant était ouvert, proposant aussi de très bons burgers ! Nous nous sommes régalés.

Un rare parasol dans le désert avec une ombre bienvenue...

Bivouac dans le désert, seuls au monde. Juste les coyotes qui hurlent au crépuscule et à l'aube.

Chaque soir à l'étape, nous trouvons un point d'eau (ruisseau). Ce soir-là, c'était à la source de Diagnus well. De l'or dans le désert !! Nous repartons le lendemain bien chargés en eau, comme chaque matin, pour être autonome toute la journée. Inquiétude quotidienne: savoir si on trouvera de l'eau le soir suivant.

Sur ces plateaux, le vent balaie le paysage (souvent de face pour nous). Les deux dernières étapes étaient bien soufflées et particulièrement éprouvantes.

Cette traversée du désert est redoutée de tous les cyclistes à cause des températures élevées pouvant dépasser les 40°. Nous avons eu de la chance avec 30° environ en cette fin août.

Le ciel s'assombrit et nous n'atteindrons pas Rawlins sans qu'un violent orage de grêle nous arrête et nous arrose copieusement. Trempés, nous finissons la journée dans un motel 6, à 90$ la nuit.



Nous quittons Rawlins sous le soleil après une bonne nuit réparatrice, linge propre et sec... Après une heure de pédalage, la pluie est de retour nous obligeant à passer trois heures à l'abri d'une buse sous la route.

Les jours suivants, beau temps le matin. Puis le vent se lève, de face, violent et en fin d'après-midi, l'orage éclate.

Sortie du désert. Nous retrouvons les arbres qui nous abritent puis les prairies. Bye bye le Wyoming ardu par ses montées incessantes et ses vents qui balaient les immenses espaces inhabités. Nous voilà au Colorado. Nous retrouvons les ranchs spacieux et colorés avec davantage de chevaux. See you up the road...
