Why Mount Washington is famous
At 6,288 ft (1,917 m) Mount Washington is the highest point of the north-eastern United States and of the Presidential Range, and with about 6,150 ft (1,875 m) of prominence it is the most topographically prominent mountain east of the Mississippi River. In the eastern United States only Mount Mitchell and Clingmans Dome are higher; what sets it apart is the weather.
Several storm tracks converge over northern New England, and the north–south wall of the Presidential Range stands across the prevailing westerly winds. The result is a summit where the annual mean temperature is about 28 °F (−2 °C), gusts reach hurricane force on around 110 days a year, precipitation falls on more than 200 days, and the sun shines for only about a third of the possible hours. On the afternoon of 12 April 1934 the staff of the young Mount Washington Observatory recorded a gust of 231 mph (372 km/h). It stood as the world's highest measured wind speed until 10 April 1996, when an automatic anemometer on Barrow Island off Western Australia recorded 408 km/h (253 mph) during Cyclone Olivia; the World Meteorological Organization recognised that reading only in 2010. Mount Washington still holds the record for the strongest wind measured outside a tropical cyclone or tornado, and for the Northern and Western Hemispheres.
The slogan "Home of the World's Worst Weather" goes back to a 1940 article by Charles Brooks, the scientist credited with founding the Observatory, titled "The Worst Weather in the World", although the article itself concluded that it probably did not. The cold is real enough: the official record low is −50 °F (−46 °C), set on 22 January 1885, and on 3–4 February 2023 a temperature of −47 °F (−44 °C) with gusts over 100 mph produced a wind chill of −108 °F (−78 °C), the lowest ever recorded in the United States.
Where it is and how to get there
The mountain stands in Coös County in northern New Hampshire, almost entirely within the White Mountain National Forest. The summit itself is Mount Washington State Park, a parcel of about 59 acres (24 ha) owned by the state. The east side drops into Pinkham Notch (2,032 ft, 619 m) on Route 16, where the Appalachian Mountain Club runs the Pinkham Notch Visitor Center, the main trailhead for Tuckerman Ravine; the Auto Road starts a few miles to the north near Gorham. On the west side, off Route 302 near Bretton Woods, are the Cog Railway's Marshfield Base Station (2,700 ft) with the Ammonoosuc Ravine and Jewell trailheads, and Crawford Notch. The two sides are about 50 miles apart by road.
There are three ways to the top:
- Mount Washington Auto Road — a private toll road on the east side, 7.6 miles (12.2 km) long, climbing 4,618 ft (1,408 m) from 1,527 ft to 6,145 ft. The average grade is about 12%, with long stretches of 18% and a final 50 yards of 22%; there are no guardrails. Cars take about 30 minutes up and descend in low gear. In 2026 the toll was $36 per adult and $15 per child aged 4–12; the road usually opens in late May (weekends from late April) and closes in late October or early November, weather permitting. A one-way hiker shuttle cost $60 per person in 2026, first come, first served and never guaranteed.
- Mount Washington Cog Railway — the world's first mountain-climbing rack railway, about 3 miles (5 km) up the west slope from Marshfield Station, with an average grade over 25% and a maximum of 37%. Biodiesel locomotives make the climb in about 45 minutes, the coal-fired steam engines in about an hour; the round trip takes just under three hours, including an hour at the top. In 2026 trains ran to the summit from 2 May to 25 October; from late October to early May they stop at Waumbek Station (about 4,000 ft).
- On foot — by a dozen or more trails; the most popular are described below.
At the summit the Sherman Adams Building houses a visitor centre, cafeteria, restrooms, gift shops, a post office and the Observatory with its museum. It is open only in the warm season (in 2026 from mid-June, with lobby and restrooms until 18 October); the stone Tip-Top House of 1853 next to it was closed for renovation in 2026. Out of season there is no public shelter on the summit at all.
Hiking routes
Tuckerman Ravine Trail (east, most popular). From Pinkham Notch the trail climbs 4.1 miles (6.6 km) with 4,280 ft (1,300 m) of gain. The first 2.4 miles follow a wide, steady track to the floor of the ravine; at about 2.1 miles the Hermit Lake Shelters have a well pump, toilets and snacks. Above the bowl the path climbs the headwall on steep rock steps, then crosses the boulder field of the summit cone. Plan on 4–5 hours up for an average fit hiker and nearly as long down. In winter and spring the headwall is avalanche terrain and the usual route is the Lion Head Winter Route, which leaves the Tuckerman Ravine Trail and climbs the ridge of Lion Head (5,033 ft) north of the bowl.
Ammonoosuc Ravine Trail (west). From the trailhead near the Cog Railway it is 3 miles and about 2,600 ft of steep, slabby climbing (3–4 hours) to the AMC's Lakes of the Clouds Hut (5,012 ft) beside two small tarns that are the highest lakes in the United States east of South Dakota; the summit is another 1.3 miles up the Crawford Path.
Crawford Path (south-west). Cut in 1819 by Abel and Ethan Allen Crawford, it is considered the oldest continuously maintained hiking trail in the United States: 8.5 miles (13.7 km) and about 4,900 ft of cumulative climbing from Crawford Notch, the last part along the open ridge of the Southern Presidentials past Mount Pierce, Mount Eisenhower and Mount Monroe. It forms part of the Appalachian Trail.
Other routes. The Lion Head, Boott Spur and Nelson Crag trails also climb from the east. The Huntington Ravine Trail scrambles up the steepest and highest headwall on the mountain; local search and rescue teams consider it the most dangerous hike in the White Mountains, and it is usually impassable until late May or June. The full Presidential Traverse covers about 19 miles (31 km) with over 8,500 ft (2,600 m) of gain; strong hikers do it in a summer day.
Tuckerman Ravine and spring skiing
The winds that scour the summit dump enormous amounts of snow into the east-facing cirques. In Tuckerman Ravine the snowpack can build up to around 55 ft (17 m), and from April into June, sometimes July, thousands of skiers climb on foot to ski runs of 40–55° such as Left Gully, the Chute, the Lip and Right Gully. The headwall was first skied in 1931, and in the 1939 "American Inferno" race from the summit the Austrian Toni Matt schussed straight over its lip, finishing in 6 minutes 29.4 seconds. Avalanches, falling ice and undermined snow are real hazards: the ravine records around 100 avalanches a year, and the Mount Washington Avalanche Center, run by the US Forest Service with a foundation, issues forecasts in winter and spring.
Permits, costs and rules
No permit or fee is needed to hike to the summit. Costs come with the alternatives: the Auto Road toll, Cog Railway tickets (book ahead; steam trains often sell out months in advance), a $10-per-person fee for hiker parking at the Cog's base station (2026), and AMC hut stays with dinner and breakfast. One-way Cog tickets down are sold only at the summit, if seats are free.
New Hampshire can bill hikers for rescue costs if they acted negligently. The voluntary hikeSafe card, sold by New Hampshire Fish and Game, covers the calendar year and protects the holder from that liability except in cases defined by state law. There is no camping on the summit or overnight parking there. Above treeline the alpine vegetation is fragile: stay on the trail and do not move rocks.
When to go and weather
The hiking season runs roughly from late May to mid-October, when the summit building, the Auto Road and the full Cog service operate. July is the warmest month, but even then the average summit high is only about 54 °F (12 °C) and nights average 44 °F (7 °C); snow can fall in any month, and William B. Curtis, a founder of American amateur athletics, died of exhaustion near Lakes of the Clouds in a snowstorm on 30 June 1900. In January the average high is about 14 °F (−10 °C) and the low −4 °F (−20 °C). The summit receives about 91 inches (2,320 mm) of precipitation a year and about 280 inches (7 m) of snow; the snowiest winter, 1968–69, brought 566 inches (14 m). Treeline is unusually low, around 4,400 ft (1,340 m) in exposed places, so most routes spend hours above it. Before setting out, read the Observatory's Higher Summits Forecast and turn back early if it is bad.
Water
There is no reliable drinking water on most trails, and the Cog Railway advises carrying food and water for a 10–12-hour round trip. In the warm season water can be refilled at the summit building, at the Lakes of the Clouds Hut (full service June to mid-September), at the well pump by the Hermit Lake Shelters in Tuckerman Ravine and at the Cog's base station. Out of season all of these may be closed. Treat any stream water, carry more on the long western and southern routes, and an insulated bottle in winter.
Mobile coverage and internet
The summit is a major communications site: the Yankee Building next to the Observatory houses equipment for cellular providers, so a signal is usually available on and near the top and in line of sight of it. Lower down, in the ravines and forest, coverage is unreliable or absent; the AMC says reception at the Lakes of the Clouds Hut is limited, and there is no Wi-Fi or charging there. Carry a paper map, as the Cog Railway and the Observatory advise. The emergency number is 911; even when a call gets through, a rescue on the mountain takes many hours to organise.
Dangers and safety
The terrain on the standard trails is not technical, and a fit novice can reach the top in good conditions. The danger is exposure: the upper mountain is open, boulder-covered ground where cloud, wind and freezing rain can arrive within an hour on a warm day in the valley. As of 2019 more than 161 people had died in the Presidential Range since record-keeping began in 1849, and a public list compiled from news reports counts 178 deaths and missing persons up to 2025, the large majority on Mount Washington, mostly from hypothermia and falls. The first recorded victim, the Englishman Frederick Strickland, died of exposure in October 1849. Avalanches and icefall in Tuckerman and Huntington ravines have killed skiers and climbers, and New Hampshire Fish and Game carries out around 200 rescues a year across the state.
The basic rules: start early, check the Higher Summits Forecast, carry warm and waterproof layers, a hat and gloves even in summer, a headlamp and a map, and turn around when the weather turns. In high winds the summit building, Auto Road and Cog can all close, and walking down is the only way off.
History and name
The Abenaki knew the mountain as Agiocochook, usually translated as "the place of the Great Spirit" or "of the Concealed One", and did not climb the summits out of respect for the spirits who lived there. In 1642 the settler Darby Field made the first recorded ascent. The mountain was probably named after George Washington by Manasseh Cutler's survey party in 1784; the name first appears on a map in 1796.
From the mid-19th century the summit became one of America's first tourist destinations. The stone Summit House, held down by chains over its roof, opened in 1852 and the Tip-Top House in 1853. The carriage road, today's Auto Road, opened on 8 August 1861. Sylvester Marsh, who had nearly died on the mountain in 1852, built the Cog Railway and it reached the summit in July 1869. The US Signal Service kept a weather station there from 1870 to 1892, one of the first mountain observatories in the world, and the present Observatory began its records in 1932.
Interesting facts
- The Observatory still measures temperature and humidity with a sling psychrometer, two thermometers whirled by hand, to keep its long climate record consistent.
- Mount Washington carries about 65 acres of alpine tundra, more than any other mountain east of Colorado.
- The Mount Washington Hillclimb Auto Race on the Auto Road dates from 1904; Travis Pastrana set the record of 5 minutes 28.67 seconds.
FAQ
How high is Mount Washington? 6,288 ft (1,917 m). It is the highest peak in the north-eastern United States and the most prominent east of the Mississippi.
How long does it take to hike up Mount Washington? By the Tuckerman Ravine Trail (4.1 miles, 4,280 ft of gain) an average hiker needs 4–5 hours up and almost as long down; strong hikers may do it in about two hours. Plan a full day of 7–10 hours, and up to 10–12 hours on the longer western and southern routes.
How difficult is it? Non-technical in summer but strenuous, with steep, rocky trails and several hours above treeline. In winter it is a serious mountaineering objective with extreme cold, wind and avalanche risk.
Can you drive or take a train to the top? Yes. The Auto Road (in 2026 $36 per adult and $15 per child) takes about 30 minutes each way in season, and the Cog Railway climbs the west side in 45–60 minutes. Both close or turn back in severe weather.
Is there water on the way? In summer you can refill at the summit building, the Lakes of the Clouds Hut, the Hermit Lake pump in Tuckerman Ravine and the Cog base station. Otherwise carry enough for the whole day and treat any stream water.
Is there mobile phone coverage? Usually on and near the summit, which hosts cellular equipment, but often none in the ravines and forest. Carry a paper map; the emergency number is 911.
When is the best time to climb Mount Washington? From late June to September, when the summit facilities are open and conditions are mildest. Even then, check the Higher Summits Forecast and carry winter layers.
Do I need a permit? No permit is needed to hike. The voluntary hikeSafe card protects against rescue bills in most cases.
