Beaver Brook Cascades, Kinsman Notch – When it comes to waterfalls in the New Hampshire White Mountains, the waterfalls in Kinsman Notch are often overlooked. I can only guess Kinsman Notch’s reputation of having rough terrain is what keeps most away from exploring this incredible Notch.
Kinsman Notch has a number of named and unnamed waterfalls, and one of the better known ones is Beaver Brook Cascades. These cascades are located on Beaver Brook, and the Appalachian Trail (Beaver Brook Trail) runs on the side of them. The earliest reference I have found to them is from the 1890s.
