Continental Divide Ride - the longest off-pavement route in
the world.
The Great Divide Mountain Bike Route (GDMBR) is Adventure
Cycling's premier off-pavement cycling route, crisscrossing the Continental
Divide north to south (we will follow this route on our off-road motorcycles). This route is defined by the word "remote."
Its remoteness equates with spectacular terrain and scenery. The entire route
is basically dirt-road and mountain-pass riding every day. In total, it has
over 200,000 feet of elevation gain.
The route is geographically divided into five regions. The
diverse nature of the regions makes for an incredible visual, sometimes
spiritual experience. The route offers something different every day — whether
it be riding conditions, scenery, points of interest, or folks along the way.
It is a route to be enjoyed for its diversity.
A wide variety of road conditions exists along this route.
Surfaces range from pavement, good gravel roads, four-wheel-drive roads,
singletrack, or old railroad beds. There is an excellent opportunity to view
wildlife such as bear, deer, wild horses, pronghorn antelope, eagles, osprey,
sandhill cranes, and other birds and animals. The route is rich in history,
with ghost towns, deserted mines, wagon routes, and old Spanish land grants.
The route is near or goes through several national parks such as Glacier,
Yellowstone, and Grand Teton. Temperatures tend to be chilly at night and cool
to warm in the days as you are in mountainous regions most of the way. Wind
really isn't a factor along the route because you spend a lot of time in the
cover of trees, with the exception of the Great Basin area. Snow, hail, and
afternoon thundershowers can be a factor. Getting up and riding early to avoid
the afternoon thundershowers is advisable. Medical help is often a long
distance off of the route, so riding within your abilities and being aware of
dangers is a must. Mosquitoes are a fact of life — take repellant.
Beginning at the Canadian border and heading south to
Helena, Montana, you are in the deep woods and steep mountains near Glacier
National Park and the Bob Marshall Wilderness. This area is native to grizzly
bear, elk, moose, mountain lion, thick woods, and has some difficult climbing.
Montana is characterized by mountainous riding in tall forests with occasional
dips into small towns. It is also noted for its friendly people. The capital
city in Montana, Helena, has less than 40,000 people and a nice small-town feel
to it. The other big town along the route is Butte, which has a definite
blue-collar, mining flavor. Montana also has the toughest downhill on the route
— nicknamed "thermarest hill" for all the thermarests it has eaten.
Even the hardiest riders have to walk this one.
From Butte to Pinedale, Wyoming, you'll be riding through
wide-open mountain valleys. The vegetation thins out into valleys with many
different varieties of sage and high-elevation alpine woods. The route crosses
the Continental Divide many times, and the climbing is longer with very steep
sections on some of the roads. You'll see many cows. You leave Montana crossing
the divide into Idaho. You are only in Idaho for 72 miles and ride along some
blue-ribbon fishing streams and an old railroad bed on the west side of
Yellowstone National Park. You'll cross into Wyoming between Yellowstone and
Grand Teton National parks on a very scenic road with some great backcountry
campsites and a genuine undeveloped hot springs. The route cuts through a
corner of the Tetons before heading east up over the divide again and then down
the west side of the Wind River Range. The prettiest alpine region on the whole
route can be found here. Just south of Pinedale, is a stretch with the worst
mosquitos on the entire route but makes for a great character builder. Farther
on there's the unforgetable sensation of riding on the crest of the divide for
several miles. You then hit an extremely picturesque section of high desert
following the Lander cutoff — part of one of the westward wagon routes. Water
is very scarce through here, so carry plenty. After dropping into the twin
ghost towns of South Pass and Atlantic City, you will cross the Great Basin — a
place of almost no drinkable water and no trees. Big northwest winds blow
across vast open territory marked with wild horses and antelope. Rawlins,
Wyoming, marks the end of the desert.
From southern Wyoming to northern New Mexico, you'll be in
the Colorado Rockies. The ascents on the route stretch out to long mountainous
climbs at elevations starting at 8,000 feet or above. Incredible aspen stands,
huge mountains, beautiful alpine meadow flora, historical tourist towns, and a
less remote wilderness setting are the characteristics of this state. Expect
early evening thunderstorms and cold nighttime temperatures. The highest pass
of the route is Indiana Pass, elevation 11,910 feet, in southern Colorado. Soon
after crossing it, you get to see firsthand what kind of scars mining can leave
on the land as you pass right through a federal Superfund site. Heading into
New Mexico, the road surface deteriorates, with much more rocky riding. Here
the countryside turns much drier, and water sources can be few and far between.
Climbs get shorter and steeper. Geographically this region is as remote as any
place in the continental United States. Mesas, cliff lines, volcanic
formations, and mountain ranges that seem to pop right out of the desert floor
are major visual features of this area. Many different cactus and grass
varieties somehow provide habitat for small rodents, snakes, and lizards.
Townspeople are right out of Old Mexico, with Spanish spoken more than English.
Late-summer monsoon rains turn roads into sloppy, red clay and can fill many of
the dry creek beds on the route in seconds. Roads are impassable until they dry
out. This area is both historically and anthropologically dominated by the rich
Native American and southwestern Spanish culture. Coming down the east side of
the Gila Wilderness is a welcome relief, with water once again available as you
head into Silver City, New Mexico, a place noted for learning about Anasazi
culture with the Gila Cliff Dwellings National Monument north of town and a
good museum at the local university. From there it is a sprint south (mostly on
pavement) to the border crossing, which consists of one building on the border
and nothing else for miles and miles.
