Overview
Mount Washington stands 6,288 feet above sea level, the highest point in the northeastern United States and the most prominent peak east of the Mississippi. It holds a well-earned reputation for having some of the worst weather on Earth. The summit sits at the convergence of three major storm tracks, producing average annual temperatures of 27 degrees Fahrenheit, fog or cloud cover about 60 percent of the time, and hurricane-force winds on more than 100 days per year.
The Tuckerman Ravine Trail, in the White Mountain National Forest, is the most popular route to the summit and the one most hikers choose for their first attempt. The 4.2-mile trail starts at the Pinkham Notch Visitor Center (2,032 ft) and climbs 4,250 feet to the summit, passing through forest, the dramatic glacial bowl of Tuckerman Ravine, and finally the exposed alpine zone above treeline. Round trip is 8.4 miles. Most hikers complete it in 6 to 9 hours depending on fitness and conditions.
This is not a casual hike. The elevation gain is relentless, the upper mountain is fully exposed to weather that can turn lethal with little warning, and the summit weather station exists precisely because conditions here are extreme. More than 150 people have died on Mount Washington since records began. Preparation, good judgment, and a willingness to turn back are more important than fitness on this mountain. Hikers who want to build toward Washington should consider Mount Lafayette via Old Bridle Path as a comparable 3,500-foot elevation gain in above-treeline terrain, or Crawford Path to Mount Pierce for a Presidential Range summit at lower commitment. The Leave No Trace principles are particularly relevant on the alpine cone above treeline, where fragile plant communities survive only by being walked on as little as possible.
The Route
Pinkham Notch to Hermit Lake Shelters (2.4 miles, 1,800 ft gain)
The Tuckerman Ravine Trail begins behind the Pinkham Notch Visitor Center, where you can fill water bottles, check current conditions posted on the bulletin board, and use the restrooms. The first 2.4 miles climb steadily through mixed hardwood and spruce-fir forest on a well-maintained, rocky trail. The grade is moderate to steep, gaining about 750 feet per mile.
At 2.4 miles, you reach the Hermit Lake Shelters area at the base of Tuckerman Ravine (3,875 ft). This is the halfway point in terms of distance, though less than half the total elevation gain. The area has eight open-front shelters and several tent platforms operated by the AMC on a first-come, first-served basis ($15 per person per night). A caretaker is on-site during summer season. There are also composting toilets and a water source.
Hermit Lake is a good rest stop and turnaround point if conditions above look bad. From here, you can see into Tuckerman Ravine, the massive glacial cirque that gives the trail its name. In spring, the ravine's headwall is a famous backcountry skiing destination, but by summer the snow is mostly gone and the route is a hiking trail.
Tuckerman Ravine Headwall (0.8 miles, 1,600 ft gain)
This is the crux of the hike. From Hermit Lake, the trail crosses the floor of the ravine (a snowfield may linger here into June or early July) and then ascends the headwall, the steep back wall of the glacial bowl. The headwall section gains about 1,600 feet in roughly 0.8 miles. It's steep, rocky, and in places requires scrambling over large boulders and ledge.
In early season, the headwall may be covered in snow and ice, which makes it significantly more dangerous. Crampons or microspikes and an ice axe are required if snow is present. Check with the Pinkham Notch Visitor Center for current conditions before starting. Once the snow melts (usually by mid-June to early July), the route is a steep but straightforward rock scramble.
At the top of the headwall, the trail emerges onto the upper cone of Mount Washington above treeline. The transition is abrupt: you go from sheltered ravine walls to a fully exposed alpine landscape.
Summit Cone (1 mile, 850 ft gain)
The final mile follows cairns across alpine tundra and rock fields to the summit. The terrain is relatively gentle compared to the headwall, but you are completely exposed. Wind, fog, rain, and cold can hit with little warning. On a clear day, the summit buildings are visible from the top of the headwall, and the walk feels straightforward. In fog, the cairns can be difficult to follow, and disorientation is a real risk.
The summit complex includes the Mount Washington Observatory (a private weather research station), a visitor center, restrooms, a snack bar, and the arrivals area for the Auto Road and Cog Railway. Yes, people drive and ride a train to the summit. After hiking 4,250 vertical feet, sharing the summit with tourists in flip-flops is part of the Mount Washington experience. Embrace it, buy a bumper sticker that says "This Car Climbed Mt. Washington," and enjoy the view.
On a clear day, you can see four states (New Hampshire, Vermont, Maine, and New York), the Atlantic Ocean to the east, and Mount Marcy in the Adirondacks to the west.
Weather: This Section Is Not Optional Reading
Mount Washington's weather is not an abstract concern. It's the primary hazard of this hike and the reason people die here.
Wind: The summit averages 35.3 mph annually. Gusts above 100 mph are recorded multiple times per year. In April 1934, the observatory recorded a wind gust of 231 mph, which held the world record for decades. Even in July and August, summit winds of 40 to 60 mph are common, and gusts above 80 mph are possible.
Temperature: The average summit temperature in July, the warmest month, is 49 degrees Fahrenheit. With wind chill, it feels much colder. On a windy day, effective temperatures at the summit can be in the 20s or 30s even in midsummer.
Visibility: The summit is in cloud cover roughly 60 percent of the time. Fog can roll in within minutes, reducing visibility to 50 feet or less. Route-finding above treeline in fog is disorienting, and hikers have become lost and died of exposure within a few hundred yards of the summit.
What to do: Check the Mount Washington Observatory's higher summits forecast at mountwashington.org before you go. This is far more useful than any general weather app. If the forecast calls for winds above 40 mph, cloud cover at summit level, or precipitation, seriously consider postponing your hike. If conditions deteriorate while you're on the mountain, turn back. The summit will still be there next weekend.
What to Expect
Terrain: The lower trail is rocky but well-maintained forest path. The ravine headwall involves steep scrambling on rock. The summit cone is exposed alpine terrain following cairns. Trekking poles help on the lower trail and summit cone but are awkward on the headwall scramble. Many hikers carry them and stow them for the headwall section.
Water: Reliable water is available at the visitor center and at Hermit Lake. Above the ravine, there is no water until the summit snack bar. Carry at least 2 liters per person from Hermit Lake.
Time: Plan for 6 to 9 hours round trip. Faster hikers do it in 5 to 6 hours, but there's no advantage to rushing. An early start (by 7 AM) is far more important than a fast pace, as it gives you time to deal with weather changes and gets you off the summit before afternoon storms.
Other hikers: Tuckerman Ravine Trail is the busiest route on the mountain. Expect company, especially on summer weekends. The trail can feel like a highway below Hermit Lake. Above the ravine, the crowds thin somewhat.
Dogs on Mount Washington
Dogs are allowed on the trail and occasionally seen on the summit. However, the conditions that make this hike dangerous for people are worse for dogs. The exposed rock above treeline is hard on paws, the weather can be life-threatening, and the headwall scramble is difficult for most dogs. If you insist on bringing your dog, keep them on leash at all times and be prepared to carry them if conditions demand it. Most experienced hikers leave their dogs at home for this one.
Permits and Logistics
WMNF Parking Pass: Required at the Pinkham Notch Visitor Center parking lot. Day passes cost $5, annual passes cost $30. The Interagency Annual Pass ($80) also works. Passes are sold at the visitor center.
No wilderness permit required for day hikes on Mount Washington.
Hermit Lake Shelters: First-come, first-served, $15 per person per night. Eight lean-to shelters and tent platforms. A caretaker is on-site during summer. This is a good option if you want to split the hike into two days: hike to Hermit Lake in the afternoon, summit the next morning when weather is typically calmer.
Cog Railway alternative: If the weather turns bad during your hike, you can potentially ride the Cog Railway down from the summit (one-way tickets are sometimes available, about $50). This is not guaranteed, and you should never count on it as a bail-out plan, but it's worth knowing about.
Tips
Start early. The single most important piece of advice for this hike. Aim to leave Pinkham Notch by 7 AM at the latest. Morning weather is generally better than afternoon weather above treeline, and you want to be off the summit cone before afternoon thunderstorms develop.
Bring more clothing than you think you need. Full above-treeline kit: waterproof shell jacket and pants, insulating layer (fleece or puffy), hat, gloves, extra socks. These items are non-negotiable regardless of the valley forecast.
Eat and drink consistently. The sustained climb burns serious calories. Eat snacks before you're hungry and drink before you're thirsty. Bonking on the headwall is miserable and potentially dangerous.
Consider the Lion Head Trail as an alternative. If Tuckerman Ravine still has snow on the headwall (common in May and June), the Lion Head Trail offers a summer route that avoids the ravine. It's slightly longer but doesn't require snow travel gear. Check conditions at the visitor center.
The descent is the hard part. After the exhilaration of the summit, you still have 4,250 feet of downhill on rocky trail. Most injuries happen on the descent when hikers are tired and less careful. Take your time, watch your footing, and use your trekking poles.
Don't skip Pinkham Notch Visitor Center. Stop in before and after your hike. The staff can give you current conditions on the mountain, and after your hike, the visitor center has food, drinks, and restrooms. The AMC also operates the Joe Dodge Lodge here if you need overnight lodging.
Getting There
Pinkham Notch Visitor Center is on Route 16, about 11 miles north of North Conway and 12 miles south of Gorham. From Boston, the drive is approximately 160 miles and takes about 3 hours via I-93 to Route 3 to Route 302 to Route 16, or via I-95 to Route 16 through North Conway. The Route 16 approach through North Conway is more direct.
The visitor center has a large paved parking lot, but it fills on summer weekends. Arrive before 7 AM on Saturdays and Sundays from June through September. An overflow lot is available nearby.
The nearest full services are in North Conway (grocery stores, restaurants, gear shops, lodging) or Gorham to the north (gas, food, basic supplies). Jackson, about 5 miles south, has several inns and restaurants. For a different style of White Mountains summit experience from the same Pinkham Notch starting point, Mount Chocorua to the south is a much more approachable above-treeline scramble at 3,490 feet. Arethusa Falls in Crawford Notch on Route 302 provides an excellent recovery hike the day after Washington. The America the Beautiful pass is accepted at the Pinkham Notch parking lot. For East Coast hikers looking to compare presidential-range terrain, the George Washington and Jefferson National Forests along the Virginia Blue Ridge share Appalachian ridgeline character without the extreme weather of the White Mountains.
