Backbone Rock and the “shortest tunnel” on TN-133 are classic Appalachian roadside photo stops: a tall, stratified rock face along the ridge and a small tunnel framed by road leading lines. Best light is sunrise to mid-morning (soft sides) and late afternoon for warm backlighting. Arrive early to beat passing traffic; photos are quick and low-cost.
