Main Wall is a climbing area in Maine's Little Concord Pond State Park, managed by State Park and Recreation. It sits among several named climbing areas, including Shagg Crag, Left End and Right End, all within about a tenth of a mile. The area draws climbers to its range of sport routes, which sit at the 5.11D to 5.14A level of the YDS scale, with the hardest of them, Vin Diesel, at 5.14A. Summer is the most comfortable time to climb. Typical July highs reach about 79°F with lows near 58°F, based on averages from a nearby weather station in Rumford. That station sits roughly 760 feet lower than the wall, so temperatures on the crag run cooler. The wall pairs well with other outings close by. Paddlers can find the Androscoggin River Trail about 2 miles away, and the J-n-J Backcountry Trail and Buck's Ledge Trail are both within 7 miles for hikers.
