Mount Liberty is a 4,459-foot mountain in the Franconia Range of the White Mountains. It is one of 6 mountains in the Franconia Range, though, only 4 of them being 4,000 footers. Mount Liberty is the second shortest, after Mount Flume.

Many people choose to hike Mount Flume and Mount Liberty on the same hike, this is known as Peak-Bagging (also mountain bagging, hill bagging, summit to summit). It is a great way to cross multiple mountains off your list in one day, not to mention have multiple views! If you choose to hike both mountains, it is wise to hike up to Mount Flume via the Flume Slide Trail, then over to Mount Liberty, and down the Liberty Spring Trail, which is also part of the Appalachian Trail. The Flume Slide Trail is extremely steep for around a mile starting at the summit. It is called the Flume Ledges. Both the views on each mountain are incredible and breathtaking.

In the decades prior to 1911, the unregulated logging practices of private timber companies in the White Mountains had resulted in a damaged landscape susceptible to both fire and flood. Fires had burned thousands of acres, and flash floods affected the water power necessary to the mills of major industrial centers downstream, such as Manchester, New Hampshire, and Lowell, Massachusetts. Concerns over losses to industry, business, and tourism, and the growing conservation movement led to citizen action. The Appalachian Mountain Club (AMC) and Society for Protection of New Hampshire Forests (SPNHF) spearheaded an effort to ensure the permanent protection of the White Mountains from further depredation. After years of lobbying and intense public pressure, Senator John Weeks of Massachusetts, a native of Lancaster, New Hampshire, introduced legislation that became known as the Weeks Act. The Weeks Act was passed by Congress in 1911, appropriating 9 million dollars to purchase 6 million acres of land in the Eastern U.S. In turn, this led to the creation of the White Mountain National Forest (WMNF) in 1918, and twenty-one other national forests throughout the north and southeast. Many of the groups who were instrumental in the passage of the Weeks Act, including the SPNHF and the AMC, are still active today, and the WMNF has grown from 7,000 acres to almost 800,000. Today, the reforested mountains and hillsides supply forest products and provide magnificent recreational opportunities while maintaining healthy watersheds and ecosystems.

The shortest trail up to the summit of Liberty is the Liberty Spring Trail, 8.2 miles there and back. It will take 10.1 miles to peak-bag both Liberty and Flume.
