The region centred on the Northeast’s highest range (Mount Washington tops out at 1,917m/6,288 ft. and claims the highest wind speeds of any summit) is a beautiful playground - and makes a ravishing road trip - in all four seasons, and winter resorts such as Attitash, Cannon Mountain, and Cranmore famed for some of the region’s best skiing and snowboarding. Much of this area is covered by the 3,039-square-km (1,173-sq.-mi.) White Mountain National Forest, with 1,900 km (1,200 mi) of hiking and mountain-biking trails (some marked with explicatory panels); 23 campgrounds; and highlights such as several restored 19th-century farmhouses; the Mt. Washington Cog Railway (so called because of its toothed rails, meshed by cog wheels), at 151 the oldest mountain train of its kind. Adjacent with similar offerings and even more historic sites is Franconia Notch State Park (including the aforementioned Cannon Mountain). And other White Mountains attractions include the Conway Scenic Railroad; glacial caves; rock climbing; 29 mostly 19th-century covered bridges; local theaters and other performance venues; another Shaker site, the Enfield Shaker Museum; the 19th-century house-museum of one of the USA’s most beloved poets, Robert Frost; lake swimming, fishing, and boating.
