Mount Washington State Park, a 60.3-acre parcel perched on the summit of the Northeast's highest peak, is surrounded by the extensive 750,000-acre White Mountain National Forest. On a clear day, views from the 6,288-foot summit extend beyond New Hampshire as far as 130 miles to Vermont, New York, Massachusetts, Maine, Quebec, and the Atlantic Ocean.

The Sherman Adams building, a modern summit building, houses The Sherman Adams Visitor Center, a cafeteria, restrooms, gift shops, the Mount Washington Observatory and its museum. The historic Tip-Top House is located adjacent to the summit building.

The Tip-Top House Historic Site

The Historic Tip-Top House is located adjacent to the geological summit. Renovated in 1986 to simulate its first construction with period furnishings.

In 1853, the Tip-Top House was the second stone house built on the summit. All materials were hauled nine miles on horses over rough trails from Randolph, N.H. Originally it was built as a competing hotel, but eventually was combined with the other as a dining room, barroom and parlor. As Access to the summit improved and the Tip-Top House fell into disuse. It went through many operations through its life span, including a printing office for Among the Clouds newspaper. After being used to house employees and hikers it was renovated into a historic site.
