HikerNerd rates the Wildcat A via Carter Notch Very hard on a six-tier scale from Easy to Most demanding. The rating comes from the route itself: its 8.6 miles, 2,912 ft of gain, and the steepest quarter mile of trail, with routes known for scrambles or ledges rated a step harder. It is the same scale our NH 4,000-footer difficulty ranking uses. Above-treeline exposure, water crossings, and winter conditions can still make a well-rated route the hardest day of your year, so check current conditions before committing.
