High Peaks Wilderness - Unit Management Plan

The High Peaks Wilderness Complex is comprised of three distinct, but interrelated units: the Ampersand Primitive Area, the High Peaks Wilderness, and the Johns Brook Primitive Corridor. While its topography varies considerably, the area is predominantly high mountain country, containing many of New York's highest peaks. The primary attraction is Mount Marcy, the state's highest peak at an elevation of 5,344 feet. The eastern portion of the wilderness is heavily used by recreationists. Western segments of the wilderness are more remote, receive substantially less use, and offer some of the best opportunities for solitude in the northeast.

For a description of recreational opportunities in the unit, please visit the High Peaks Wilderness recreation page.

Status of the UMPs

The Department adopted a Unit Management Plan (UMP) for the High Peaks Wilderness in 1999. In 2018, the Adirondack Park State Land Master Plan was amended to add the former Dix Mountain Wilderness into the High Peaks Wilderness. A UMP for the Dix Mountain Wilderness was adopted in 2004. If you have questions about either UMP, please email us at

2000 Amendment - Little Porter Mountain Trail Relocation
