The trail measured 2,168.1 miles in 2001. The total distance of the trail changes slightly from year to year as trail maintenance groups reroute the trail as needed. An Appalachian Trail thru-hike takes between five and seven months to complete the entire trail. (About 20 percent of hikers who begin the trail will complete it.) The average cost of an Appalachian Trail thru-hike is approximately $3,000 (about $1.50 per mile), not including gear.
As such, many cost estimates leave these expenses out of final cost calculations. On the Appalachian Trail Costs. The Appalachian Trail Conservancy recommends $1,000 per month for the average hiker. Given the average completion time of five to seven months, total on-trail spending can be from $5-7,000 per person. Many hiking blogs and forums corroborate this estimate with outliers in either direction. Experienced thru-hikers with a knack for budgeting will spend less, while some treat the AT like a long vacation and spend $10,000 or more.
