Great Divide Mountain Bike Route

The prime season for cycling the Great Divide Mountain Bike Route typically runs from late June through September. However, be prepared for variable weather; snow can occur at higher elevations at any time, and early evening thunderstorms and cold nighttime temperatures are common in the Colorado Rockies. Starting southbound in mid-June often allows snow to melt in the northern sections while avoiding the peak heat in New Mexico later in the season.

Generally, no specific permits or fees are required to cycle the Great Divide Mountain Bike Route itself, as it primarily utilizes public lands and existing roads. However, if you plan to camp in designated campgrounds within National Parks or other specific areas along the route, standard camping fees may apply. Free camping is often available in National Forest lands.

The Great Divide Mountain Bike Route stretches from Alberta, Canada, to Antelope Wells, New Mexico. Common starting points include Roosville, Montana (near the Canadian border) for southbound riders, or Antelope Wells for northbound riders. Given its immense length, there isn't a single designated parking area. Riders typically arrange parking in towns near their chosen starting or ending points, such as Whitefish, Montana, or various towns along the route. Many sections are accessible from smaller towns with limited parking options.

The Great Divide Mountain Bike Route traverses a vast array of public lands, including National Forests, BLM land, and some private property. While dogs are generally permitted on leash in many of these areas, specific regulations can vary. Given the route's remoteness, potential encounters with wildlife (including grizzly bears in Montana), and the need for extensive self-sufficiency, bringing a dog requires significant planning and preparation. It's crucial to research local regulations for each section you plan to ride and ensure your dog is conditioned for such a strenuous journey.

The route is predominantly unpaved, with about 90% consisting of high-quality dirt and gravel roads, and some unmaintained tracks. You'll encounter varied surfaces, from smooth pavement to rutted dirt, and even sections that may require walking your bike. Expect constant elevation changes and long, steep mountainous climbs, especially at higher elevations. The southern sections in New Mexico often feature deteriorating road surfaces and more rocky riding.

The route offers abundant opportunities for wildlife viewing. You might encounter bears (including grizzlies in Montana), deer, wild horses, pronghorn antelope, and various bird species. Being prepared for wildlife encounters, especially with bears, is essential, and carrying bear spray is recommended in certain areas.

Cycling the entire 2,700 to 2,800-mile route is a significant undertaking. For touring cyclists, it typically takes anywhere from 6 to 10 weeks, depending on daily mileage, fitness levels, and the amount of time spent exploring or resting. Racers in the self-supported Tour Divide often complete it in under three weeks, but this is an extreme pace.

The Great Divide Mountain Bike Route is a challenging and remote route, generally not recommended for beginner cyclists. It requires intermediate off-road mountain biking skills, significant physical and psychological endurance, and strong self-sufficiency. Riders will face over 200,000 feet of elevation gain, variable weather, and long stretches between resupply points. While not highly technical, its scale and remoteness demand experience.

The route is celebrated for its remote and spectacular scenery. Highlights include the Flathead Valley in Alberta, Grand Teton National Park, the vast Great Divide Basin in Wyoming, South Park, Boreas Pass in Colorado, Polvadera Mesa, and the Gila Wilderness in New Mexico. You'll traverse wild river valleys, remote mountain wilderness, open grasslands, and high deserts. While not directly on the main route, nearby attractions like Historic Whitefish, Fish Trails Bike Path, Brush Bay, and Lazy Bay offer additional scenic beauty.

Yes, while primarily following its own dedicated path, the Great Divide Mountain Bike Route does intersect and utilize sections of other trails. Notably, it incorporates parts of the Great Divide Mountain Bike Route (80% of the route), and in specific areas like Whitefish, Montana, it may briefly share paths such as the Fish Trails Bike and Pedestrian Path, Colorado Ave Shared Use Path, Baker Underpass South, and the Whitefish Trail - Swift Creek Loop.

The highest point on the Great Divide Mountain Bike Route is Indiana Pass in Colorado, reaching an elevation of 11,910 feet. This section, like many others in the Colorado Rockies, presents significant climbs and can experience snow even in summer months.

Yes, the Great Divide Mountain Bike Route offers numerous opportunities for free camping, particularly within National Forest lands and Bureau of Land Management (BLM) areas. This allows for a truly adventurous and self-sufficient touring experience. Riders should be familiar with Leave No Trace principles and local regulations for dispersed camping.
