The rules about vehicles on the Appalachian Trail are very clear. You can’t ride a bicycle on it. Nor
can you use a motorized vehicle.
36 CFR 7.100 – Appalachian National Scenic Trail. (a)What activities are prohibited? (1) The use of bicycles, motorcycles or other motor vehicles is prohibited.
The US Forest Service knows this and says so on the website for the George Washington & Jefferson National Forest:
The A.T. is marked with white vertical paint blazes, two-inch by six-inch. It is a foot trail – travel by horse, bicycle, or motorized vehicles is not allowed.
And according to a more specific order for this national forest, “Vehicles, horses, pack animals’ and bicycles” are prohibited on the A.T. unless there is “a permit specifically authorizing the otherwise prohibited act or omission.” We have seen no such permit, nor does any closure order we have seen state that Forest Service personnel are authorized to use motorized vehicles on the A.T.
“Violations of these prohibitions are punishable by a fine of not more than $5,000 for an individual or $10,000 for an organization, or imprisonment for not more than 6 months, or both. (16 U.S.C. 551, 18 U.S.C 3559 and 3571).”
