Overview
Mount Lafayette is the highest peak on Franconia Ridge at 5,260 feet and one of the most popular summit hikes in the White Mountains. The Old Bridle Path is the most direct route to the top: 3.8 miles one way with 3,500 feet of elevation gain, returning the same way for an 8.6-mile round trip (though many hikers extend their day by doing the Franconia Ridge Loop instead of retracing their steps). Directly below at the trailhead, Lonesome Lake provides the best easy-to-moderate option from Lafayette Place Campground for those in the group who aren't ready for 3,500 feet of gain.
The Old Bridle Path has been in use since the 1830s, when it served as a horse trail to Greenleaf Hut's current location. Today it's a well-trodden hiking route that passes through forest, breaks above treeline at about 3 miles, and reaches the AMC's Greenleaf Hut before a final exposed push to the summit. The views from the top are among the best in New England: the Pemigewasset Wilderness sprawls to the east, the Franconia Ridge extends south over Mount Lincoln and Little Haystack, and on clear days you can see the Presidential Range, the Green Mountains of Vermont, and the lakes region to the south.
This is a strenuous hike by any measure. The 3,500 feet of elevation gain over 3.8 miles translates to an average grade of about 17 percent, and some sections are steeper. The final mile above Greenleaf Hut is exposed to weather with no shelter. If you're comfortable with sustained climbing and above-treeline conditions, Lafayette via Old Bridle Path is a deeply satisfying day in the mountains.
The Route
Lafayette Place to Greenleaf Hut (2.7 miles, 2,500 ft gain)
The trail starts from the hiker parking lot at Lafayette Place Campground on I-93. A pedestrian tunnel takes you under the highway, and the trail begins climbing immediately through mixed hardwood forest (birch, beech, maple). The first mile is a steady climb through the trees with limited views but pleasant forest walking.
At about 1.2 miles, the trail crosses a small brook (the last reliable water source before Greenleaf Hut) and begins to steepen. The next mile gains about 1,200 feet as the trail transitions from hardwoods to spruce and fir. The footing becomes rockier, with sections of moderate scrambling over ledge and roots.
At roughly 2 miles, you'll reach the first open views as the trail passes over rocky knobs on the ridge. Looking east, you can see into Walker Ravine, a steep glacial cirque. These viewpoints offer the first real glimpse of the terrain ahead and a good excuse to catch your breath.
At 2.5 miles, the trail enters the subalpine zone. Trees shrink to stunted krummholz (the wind-bent spruce and fir that characterize the upper forest). At 2.7 miles, Greenleaf Hut appears on a shoulder at 4,200 feet, with Mount Lafayette's summit cone visible directly above and the Franconia Ridge extending south.
Greenleaf Hut
Greenleaf Hut is one of eight AMC backcountry huts in the White Mountains. It sits on an exposed shoulder at 4,200 feet with views of the ridge, Eagle Lake below, and the Pemigewasset Wilderness to the east. The hut operates at full service from June through mid-September, offering bunk rooms with dinner and breakfast (roughly $155 to $175 per person per night, reservations required). During the day, the hut sells snacks, lemonade, and hot soup to walk-in hikers.
The hut has a water source and composting toilets. It's a good place to rest, refuel, and assess the weather before committing to the final exposed mile to the summit. If clouds are building, wind is picking up, or you hear thunder, the hut is a sensible turnaround point.
Greenleaf Hut to Summit (1.1 miles, 1,000 ft gain)
From the hut, the Greenleaf Trail climbs steeply northwest toward the summit. Within a few hundred yards, you're above treeline. The trail is marked with cairns and yellow paint blazes on rock. The terrain is open, rocky, and fully exposed to wind and weather.
The first half-mile climbs the southeast face of Lafayette with increasingly expansive views opening up behind you. The grade is steep and the footing requires attention, with loose rocks and some scrambling. At about 0.7 miles above the hut, you'll reach the ridge proper. From here, the Franconia Ridge Trail comes in from the south, connecting to Mount Lincoln and Little Haystack.
The final 0.4 miles follows the ridge north to the summit, which is marked by a large cairn. The summit of Mount Lafayette offers a full 360-degree panorama. To the south, Franconia Ridge drops away toward Mount Lincoln. To the east, the Pemigewasset Wilderness fills the horizon, a vast roadless area of peaks and valleys. To the north, the Garfield Ridge extends toward Galehead Mountain. To the west, the view reaches into Vermont. On exceptionally clear days, you can pick out Mount Washington to the northeast, 15 miles distant.
What to Expect
Terrain: The lower trail is rocky with roots, typical of White Mountain trails. The section above Greenleaf Hut is exposed alpine terrain on rock and scree. Trekking poles are helpful throughout and particularly useful on the rocky descent.
Exposure: The final 1.1 miles above Greenleaf Hut is entirely above treeline with no shelter from wind, rain, lightning, or sun. The summit of Lafayette is one of the more exposed points in the White Mountains outside the Presidential Range.
Crowds: Old Bridle Path is one of the busiest trails in the forest. On summer weekends, you'll share the trail with dozens of other hikers, many heading for the full Franconia Ridge Loop. Midweek is notably quieter. September weekdays after Labor Day are ideal.
Water: A brook crossing at about 1.2 miles is the last reliable water before Greenleaf Hut. The hut has a water source. Above the hut, there is no water. Carry at least 2 liters for the round trip from the hut to the summit and back.
Time: Most hikers complete the out-and-back in 6 to 8 hours. Allow at least 3 to 4 hours for the ascent and 2 to 3 hours for the descent. The rocky trail punishes hurried descents.
Combining with Franconia Ridge Loop
Many hikers use Old Bridle Path as the descent route for the Franconia Ridge Loop. The standard loop goes up Falling Waters Trail to Little Haystack, traverses the ridge north over Mount Lincoln and Mount Lafayette, then descends Old Bridle Path. If you're considering this option, the full loop is 8.6 miles with 3,900 feet of gain and adds the spectacular 1.7-mile above-treeline ridge traverse between Little Haystack and Lafayette. It's one of the best hikes in the eastern United States and worth the extra effort if conditions are good.
However, doing Lafayette as an out-and-back via Old Bridle Path has its own advantages. You avoid the steep, slippery scramble on the upper Falling Waters Trail. You pass Greenleaf Hut on both the way up and the way down (handy for supplies and weather checks). And if conditions deteriorate, your retreat route is the same trail you ascended, so there's no route-finding uncertainty.
Weather
The weather warnings for Franconia Ridge apply equally to Mount Lafayette. The summit is above treeline and exposed to the same storm systems that affect the Presidential Range. Wind, fog, rain, hail, and electrical storms can develop rapidly.
Check the Mount Washington Observatory's higher summits forecast (mountwashington.org) before your hike. This forecast covers all major above-treeline peaks in the White Mountains, not just Washington.
Know your turnaround points. Greenleaf Hut is the logical place to decide whether to continue. If the summit is socked in, if winds above the hut feel stronger than you're comfortable with, or if you hear thunder in the distance, the hut is a perfectly good destination. The views from the hut area are excellent, and there's no shame in making a weather call.
Afternoon thunderstorms are common in summer. Plan to be off the summit and below treeline by early afternoon. An early start (before 7 AM) makes this easy.
Dogs on Mount Lafayette
Dogs are allowed on the trail. The lower portion through the forest is fine for most dogs. Above Greenleaf Hut, the terrain becomes more challenging: exposed rock, steep scrambling, and full exposure to weather. Many dogs can handle it, but you need to honestly assess your dog's fitness and temperament. The bigger concern is the fragile alpine vegetation. Dogs stepping off-trail above treeline damage plants that grow fractions of an inch per year. Keep your dog on leash and on the trail at all times.
Permits and Logistics
WMNF Parking Pass: Required at Lafayette Place. Day passes cost $5, annual passes cost $30. The Interagency Annual Pass ($80) is also accepted.
No wilderness permit required.
Greenleaf Hut reservations: Book through the AMC website for overnight stays. During the day, no reservation is needed to stop for snacks and water.
Tips
Start early. Arrive at the trailhead by 7 AM at the latest on weekends. This secures parking, puts you on the summit before the heat of the day, and gets you below treeline before afternoon storms.
Bring full above-treeline gear. Waterproof jacket and pants, insulating layer, hat, gloves. The summit of Lafayette can be 30 degrees colder and dramatically windier than the parking lot. Conditions can change in minutes.
Eat before the hut. The climb from the trailhead to Greenleaf Hut is the sustained effort of the day (2,500 feet in 2.7 miles). Eat snacks and drink water consistently during this section. Arriving at the hut depleted makes the final mile to the summit much harder than it needs to be.
Don't underestimate the descent. The 2.7 miles from Greenleaf Hut to the parking lot is rocky and steep. Tired legs and inattentive footing cause most injuries on this trail. Slow down, watch your steps, and use your trekking poles.
Consider an overnight at Greenleaf Hut. Splitting the hike into two days (hike to the hut in the afternoon, summit the next morning, descend) makes the experience more relaxed and gives you a better chance of catching a clear summit morning. The hut experience itself is memorable: a hot dinner, good company, and a sunrise over the Pemigewasset Wilderness.
Getting There
Lafayette Place Campground is on I-93 in Franconia Notch State Park, about 130 miles north of Boston. Take I-93 North the entire way. The drive takes about 2 hours and 15 minutes without traffic. The trailhead parking lot is separate from the campground. Follow signs for "Hiker Parking" when you exit I-93.
From North Conway, take Route 302 West to Route 3 North to I-93 South through Franconia Notch. About 1 hour and 15 minutes.
The nearest full services are in Lincoln, about 5 miles south on I-93. Gas stations, restaurants, grocery stores, and gear shops are all available. Franconia, about 2 miles north, has a few restaurants and a general store. For a White Mountains summit comparison, Mount Washington via Tuckerman Ravine is another 1,000 feet higher and significantly more demanding in weather exposure. Mount Chocorua in the southern Whites offers a similar above-treeline scramble at a more approachable 3,490 feet. The America the Beautiful pass is accepted at Lafayette Place WMNF day-use parking. The George Washington and Jefferson National Forests along the Virginia Blue Ridge offer a useful comparison for ridge hiking in the southern Appalachians for multi-region trip planners.
