White Mountains (New England)

The White Mountains are a mountain range in northern New Hampshire, United States, forming the most rugged portion of the northern Appalachian chain and containing New Hampshire’s highest summit, Mount Washington (6,288 ft / 1,917 m).

The area is known for its concentrated high peaks and alpine ridgelines. Popular highlights include summit access on Mount Washington, the exposed traverse of Franconia Ridge including Mount Lafayette (5,249 ft), and extensive hiking on marked trails; the region also contains many downhill ski areas and winter climbing routes. Scenic routes such as the 34.5-mile Kancamagus Highway and deep glacial passes like Crawford Notch provide roadside viewpoints and trailheads.

The mountains were shaped by tectonic uplift and repeated Pleistocene glaciation; human use shifted from seasonal subsistence and timbering to 19th-century recreational tourism. The Mount Washington Cog Railway opened to the summit in 1869, and the Mount Washington Observatory was established in the 20th century, reflecting the area’s long association with mountain weather, science and visitor access.

Geographically the range sits mainly within northern New Hampshire, with a small portion extending into western Maine, and much of it lies inside the federally managed White Mountain National Forest. The region is accessible by multiple state highways and is a few hours’ drive north of the Boston metropolitan area.
