Franconia Notch State Park is a public recreation area and nature preserve that straddles eight miles of Interstate 93 as it passes through Franconia Notch, a mountain pass between the Kinsman Range and Franconia Range in the White Mountains of northern New Hampshire, United States. The northern part of the park, including Cannon Mountain and Echo and Profile lakes, is in the town of Franconia, and the southern part, including Lonesome Lake and the Flume, is in Lincoln. Attractions in the state park include the Flume Gorge and visitor center, the Old Man of the Mountain historical site, fishing in Echo Lake and Profile Lake, and miles of hiking, biking and ski trails.
The park is home to Cannon Mountain, a state-owned ski resort started in the 1930s. The mountain is named for a rock formation in the shape of a cannon found on the summit, but the "Old Man of the Mountain" formation was by far the more famous; it collapsed in May 2003. Cannon is also famous for being one of the most challenging hills in New England. It boasts an aerial tram, which runs year-round, ferrying sightseers to the summit in the summer time and skiers in the winter.
