This loop is consistently rated as a strenuous and difficult hike, considered one of the hardest day hikes in the Northeast. Expect relentless steep ascents and descents, particularly on the Wildcat Ridge Trail, which includes a half-mile section dropping over 1,000 feet. It's physically and mentally taxing, best suited for very fit individuals.
The terrain is rugged and varied. You'll encounter rocky paths, large and small boulders, mud, and tree roots, often requiring scrambling. In flatter, wetter areas, bog bridges are present to help with navigation. Be prepared for significant elevation changes and uneven footing throughout.
The trail offers spectacular views despite its difficulty. Mount Hight is frequently highlighted for its exceptional panoramic vistas. From various points along the ridges, you can enjoy stellar views of Mount Washington, the Presidential Range, the Great Gulf, and the Baldface Range. The summit of Wildcat D also provides sweeping views of the Presidentials across the valley.
Yes, the route incorporates sections of several official trails. A significant portion follows the Appalachian Trail (73% of the route). You'll also hike on the Wildcat Ridge Trail (34%), Imp Trail (19%), North Carter Trail (11%), and Carter Dome Trail (9%).
Generally, dogs are permitted on trails within the White Mountain National Forest, but they must be kept on a leash at all times. Given the extreme difficulty and rugged terrain of this specific loop, it might be overly challenging for some dogs. Consider your dog's fitness and experience with strenuous, rocky hikes before bringing them.
The best time to hike is typically from late spring through early fall (June to October) when the weather is more stable and snow/ice are less prevalent. Fall offers beautiful foliage. Winter conditions can be extremely harsh, requiring specialized gear and experience due to deep snow, ice, and high winds, making it suitable only for experienced winter mountaineers.
While there are no specific permits required for hiking the trails themselves, parking at many trailheads within the White Mountain National Forest requires a recreation pass. The most common is the 'America the Beautiful' pass or a local White Mountain National Forest pass. Daily passes can often be purchased on-site at trailheads via self-service envelopes. Always check the specific trailhead for current requirements.
Beyond the stunning views, you'll pass several significant features. These include the beautiful Carter Notch Pond and the AMC Carter Notch Hut. The route also traverses six of New Hampshire's 4,000-footer peaks: Wildcat Mountain (Wildcat A), Carter Dome, South Carter Mountain, and Middle Carter Mountain. You'll also find Zeta Pass and the picturesque Glen Ellis Falls nearby.
Specific parking information can vary, but common access points for sections of this loop are often found near the Wildcat Ski Area or along Route 16. Given the length and difficulty, some hikers arrange shuttles or use two cars for a point-to-point hike if not completing the full loop. Always arrive early, especially on weekends, as parking lots can fill quickly.
Yes, the AMC Carter Notch Hut is located directly on the route. This provides a unique opportunity for an overnight stay, allowing hikers to break up the challenging traverse into a multi-day trip. Reservations are typically required for hut stays.
Given the trail's difficulty and length, essential gear includes sturdy hiking boots with good ankle support, plenty of water (more than you think you'll need), high-energy snacks, rain gear, extra layers of clothing (even in summer), a map and compass/GPS, headlamp, first-aid kit, and sun protection. Trekking poles are highly recommended for the steep ascents and descents.
