bike touring on GDMBR (Great Divide Route)
The Grand Tetons and the mountain vistas we’d been expecting on the Great Divide Route.

As we zipped past the towering peaks of the Tetons, hail pelted us with a devious force.  We were cold.  And under normal circumstances we’d have been miserable.  But not today.  The Tetons rose before us, and we were awestruck by their beauty.

Finally, here were the views we’d been expecting from Great Divide Mountain Bike Route.  The mighty Rockies in all their splendor.

All the stormy weather gave me a chance to try out my new Showers Pass rain gear. Happy to report I stayed surprisingly dry.  Very happy to see the National Parks working hard to cut down on plastic waste!

GDMBR in Wyoming

The official Great Divide Mountain Bike Route Route darts out of the Tetons fairly quickly and leads riders up Union Pass.  Wildfires had been raging in this part of Wyoming and conflicting information was bouncing around.   Some sources claimed the pass was closed and wouldn’t re-open for several weeks.  Others insisted the fire had already jumped across Union Pass road and travel in the area was now safe.

Not being able to nail down concrete road closure info (and pleased at the thought of spending more time in the Tetons) we opted for an alternate route passing through the popular resort town of Jackson.  It was August, so naturally, Grand Teton National Park was overrun with visitors.  Busloads of camera-toting tourists disembarked at all the scenic spots and jostled for space,  snapping selfies posed in front of majestic mountains and pristine lakes.  Luckily we could trundle by on our bikes and steer clear of the hoards.

Water on the GDMBR

In the pleasant town of Pinedale, we rested up for a few days and prepared for the Big Empty.  So far on GDMBR, stocking up on water and provisions had been fairly straightforward.  We’d stumble into towns with grocery stores every couple of days.  Fast-flowing streams were plentiful and with the help of our Sawyer filter, we’d have clean drinking water within minutes.

Dry days ahead

Outside of Pinedale, lay Wyoming’s Red Desert. On the entire GDMBR, this section is one of the driest and most sparsely inhabited.  Careful planning is essential.

This is more typical of GDMBR scenery.


The Red Desert

This 6 million-acre region of southwestern Wyoming is the largest unfenced area left in the Lower 48.  I’m pretty sure The Red Desert is larger than at least a couple of countries we’ve biked (Swaziland, Lesotho).

The unforgiving land is inhabited by herds of wild horses, 50,000 pronghorn and very few humans.  Energy companies in search of oil, natural gas, uranium and coal have recently started exploiting the desert’s riches.   Oil wells, drilling machinery and worker camps now blight the bleak and barren landscape.

The area has been compared to the steppes of Mongolia.  For us, the Red Desert conjured up parts of Oman.  After mountains, deserts are our favorite terrain.  We love the quality of the light and the endless vistas.  The biggest challenges of desert riding are water and wind.

Since the GDMBR is such a popular route, info on water is readily available.  The longest stretch without water is the 60 miles (100 kilometers) between Diagnus Well and A&M Reservoir.  Luckily for us, the weather was cloudy and we didn’t drink much.  Winds in the Red Desert can be ferocious, but we were mostly spared their force.

Not far out of Pinedale we hit a series of roller-coaster ups and downs. These were fairly fun as velocity took us nearly to the top of the next climb.


Our first night camping out of Pinedale. We’d put in a long day but wanted to make it to near a water source near a river.


The entire Great Divide Mountain Bike Route is packed with history. South Pass City has been restored to its glory days in the 1800’s as a gold rush city.


Riding towards remote Diagnus Well (and one of the few known sources of water).


The land is empty and remote. We pass just a handful of cars and motorcyclists. Luckily our GDMBR GPS tracks are easy to follow.


Wild pronghorns roam the Red Desert.


Oil wells are a less welcome sight.

Adios Wyoming…the high mountains of the Colorado section of the GDMBR await.
