The Mount Washington Cog Railway is located in Bretton Woods, New Hampshire, USA. It climbs Mount Washington, the highest peak in the Northeastern United States.The railway is about 3 miles (~5 km) long, and it climbs from an elevation of approximately2,700 feet (820 meters) at its base to the summit of Mount Washington at 6,288 feet (1,917 meters).
The average grade of the track is more than 25%, with the steepest ection being around 37.41%. The round trip is about three hours, including a stop at the summit, and let me tell you, this is New Hampshire's (and probably the whole East Coast’s) most epic adventure!
