Best time to visit Mount Washington State Park
Late June through early September is the prime window, when the Mount Washington Auto Road and Cog Railway are fully open, summit trails are snow-free, and the Sherman Adams summit building is staffed daily. July and August bring the mildest temperatures but also the thickest crowds and frequent fog, so weekday visits are best. Early fall, especially mid-September to early October, delivers peak foliage in the valleys and clearer long-range views, though summit temperatures drop sharply and high winds become more common. Late spring and late fall are shoulder seasons when roads may open or close depending on snow.

Things to do at Mount Washington State Park
- Drive or Ride the Mount Washington Auto Road EasyRV parking available
The Auto Road is the classic way to reach the summit, climbing 7.6 miles from NH Route 16 to the parking area beside the Sherman Adams summit building. Guided stage tours in vans are available for visitors whose vehicles cannot make the climb, including most RVs. Earn the famous This Car Climbed Mount Washington bumper sticker at the base.
- Ride the Mount Washington Cog Railway EasyRV parking available
The Cog Railway is a historic rack-and-pinion train that climbs the west side of the mountain from Marshfield Base Station near Bretton Woods to the summit. The ride takes about three hours round trip and offers expansive views above tree line. Large paved parking at the base accommodates RVs.
- Hike the Tuckerman Ravine Trail StrenuousRV parking available
One of the best ways to experience the mountain is to hike up the Tuckerman Ravine Trail from the Pinkham Notch Visitor Center. The route climbs about 4.2 miles and 4,250 feet to the summit through a glacial cirque famous for spring skiing. Always check in at the Center before leaving on a hike, as the weather is highly variable and can change quickly.
- Explore the Extreme Mount Washington Museum Easy
This interactive museum inside the Sherman Adams summit building is operated by the Mount Washington Observatory and explains the mountain's legendary weather. Exhibits include a hurricane-force wind simulator and displays on the record 231 mph gust recorded at the summit. It is the best indoor activity on a foggy day.
- Walk the Summit Loop and Observation Decks Easy
Short paved and stone pathways circle the summit from the Sherman Adams building to the actual high point marker and observation decks. On clear days visitors can see across four states, Quebec, and out to the Atlantic Ocean. Stay on marked paths to protect fragile alpine vegetation.
- View Alpine Wildflowers Easy
Wonderful arrays of blooms stand out in sharp contrast to the green forests and gray broken rocks of the alpine zone, but visitors must not stray from the trails when visiting alpine zones, as this fragile environment can be destroyed by one misplaced step. Late June and early July are best for rare arctic-alpine species. Trails near the summit offer easy viewing.
- Hike Lion Head Trail StrenuousRV parking available
Lion Head is a popular alternative summit route starting from Pinkham Notch, often used when Tuckerman Ravine is closed for avalanche danger. The trail climbs steeply above tree line with panoramic views of Huntington Ravine and the Presidential Range. Round trip is roughly 8.4 miles with significant elevation gain.

How to get to Mount Washington State Park
The park sits at the summit, but vehicle access is via the Mount Washington Auto Road off NH Route 16 in Gorham, roughly 2.5 hours north of Manchester and about 3.5 hours from Boston. You can reach Mount Washington via Interstate 93, then route 3 north to its intersection with route 302, following route 302 east to Glen, New Hampshire. The Auto Road prohibits most RVs, trailers, and oversized vehicles due to its steep 12 percent average grade, narrow lanes, and sharp drop-offs, so RV travelers should park rigs at the base and take the guided stage tour or hike and ride the Cog Railway from Bretton Woods instead. The nearest airport for fly-and-rent trips is Portland International Jetport in Maine, about 2 hours away, with Manchester-Boston Regional as another option.
