Location: Jasper, Alberta (Canada) to Antelope Wells, New Mexico
Why you should ride it: This epic 3,083-mile route, the longest off-pavement route in the world, crisscrosses the Continental Divide from Jasper in Alberta, Canada to Antelope Wells, New Mexico with more than 200,000 feet of elevation gain.
While riding on the primarily dirt-roads and mountain passes, you may see an array of wildlife, including bears, deer, wild horses, pronghorn antelope, eagles, osprey, and sandhill cranes, says Trek Travel guide Terra James. The route also charts directly through or otherwise skirts several of the most popular National Parks, including Glacier in Montana, and Yellowstone and Grand Teton in Wyoming. Because of snow, the route is best tackled in the summer or early fall months.
