Franconia Ridge Trail Loop

This roughly 8.1-mile loop climbs Falling Waters Trail to Little Haystack, crosses the exposed Franconia Ridge over Mount Lincoln and Mount Lafayette, then descends Greenleaf Trail past Greenleaf Hut and returns on Old Bridle Path. It gains about 4,000 feet and is exceptionally strenuous; allow a full day, with around eight hours a realistic planning estimate before longer breaks or difficult conditions. Official sources describe it as just over eight miles, while independently mapped versions run longer because tracks and route details vary. The mapped loop follows the current official alignment.

The first long climb stays in the forest beside streams and waterfalls, with steep, rocky footing on the way to the falls viewpoints. Falling Waters was realigned in 2026: follow the current signs and new trail tread, and do not use the closed former streamside sections shown on older tracks. A separate signed spur reaches the falls; it is not part of this loop’s stored line. Once the path reaches Little Haystack, it breaks out of the woods and onto the ridge.

From Little Haystack, the route follows open, rocky alpine terrain over Mount Lincoln to Mount Lafayette, with wide views across the Pemigewasset Wilderness, the Notch, and surrounding ranges when skies are clear. This stretch is the defining reward and the main exposure. Cairns mark the high path; fog can obscure them and make the route harder to follow. Weather on the summits can be markedly colder and windier than at the trailhead, and fog or lingering snow can occur outside winter. Check the higher-elevation forecast before choosing this hike.

From Lafayette, descend Greenleaf Trail to Greenleaf Hut, set near the small alpine tarns around 4,200 feet, then take Old Bridle Path back toward the trailhead. The hut is the loop’s only confirmed on-route service stop: water refills, hot drinks and bathrooms are available seasonally, while service level and day-hiker options vary. Do not count on it as an open or stocked stop without checking its operating information. Old Bridle Path is steep and rocky in places; wet, smooth rock makes the descent more demanding. Agony Ridge offers a view back toward the summits before the path drops into the forest.

The northbound Falling Waters / Old Bridle Path trailhead is the route’s starting point. Lafayette Place Campground on the southbound side is another official access, connected beneath I-93 by a pedestrian tunnel. Both trailhead areas have limited parking and can fill early. Seasonal overflow parking and a shuttle from the Cannon Aerial Tramway may be available; verify the current schedule before relying on it. Parking on the I-93 shoulder is prohibited. Pets are permitted on the hiking trails; keep dogs leashed, including at developed trailheads, and follow the state’s six-foot maximum leash rule.

The four-trail loop was built between 1826 and 1958 and is now maintained through a partnership involving New Hampshire State Parks, the White Mountain National Forest, the Appalachian Mountain Club and other trail crews. The ridge contains one of the largest connected alpine tundra areas in the eastern United States. Its low-growing plants recover slowly after trampling, so stay on the constructed tread even where the rocks make a tempting shortcut.
