Mount Washington State Park

Mount Washington State Park is a mountain summit park in New Hampshire at the highest point in the northeastern United States, located at 6,288 feet elevation. The park covers about 60 acres around the summit and includes several buildings, including a museum and historic structures.

The area was first developed in the 1850s when the Tip Top House was built as a hotel and printing office to serve visitors. The original structure remains on the summit and became part of the state park system established in the mid-20th century.

The Sherman Adams Summit Building contains the Mount Washington Observatory Museum, where visitors can learn about the scientific work conducted on the mountain. The museum tells the story of how this location became important for understanding weather and climate in the region.

Visitors can reach the mountain via the Auto Road, Cog Railway, Appalachian Trail, or various hiking trails from nearby notches. It is wise to prepare for changing weather conditions and bring warm clothing, as the summit is significantly colder than the valley below.

On clear days, visitors from the summit can see across multiple states and even to the Atlantic Ocean. This far-reaching view makes any sunny day on the peak particularly rewarding.
