The Grand Canyon is one of the wonders of the natural world. Since it is a National Park, there are very few opportunities for mountain biking, as mountain biking is not permitted in most National Parks. The Grand Canyon South Rim is roughly 1.5 hours of driving from Flagstaff.
That said, a bicycle is a great way to get from and to Tusayan and around the South Rim Grand Canyon Village, as there are many multi-use paths and roads where bicycles are permitted. Traffic congestion can get pretty bad at the Canyon in the prime seasons, so a bike might be faster than a car, and an infinitely more enjoyable way to get around. Because of traffic and lane widths, we don’t recommend road riding on the road between Grand Canyon Village and Desert View.
The North Rim of the Grand Canyon does afford some mountain bike friendly opportunities. Be aware that it takes roughly 4.5 hours to drive to the North Rim of Grand Canyon from either Flagstaff or the South Rim, as there are no roads across the Canyon. The road in and out of the North Rim from Jacob Lake is pretty nice for road riding as well.
