Located north of New Hampshire's central plateau, lies the White Mountains National Forest, cloaked with forests and laced with streams. Among the ranges and ridges are the highest mountains in the Northeast, the Presidential Range, which culminate in the bare granite summit of 6,288-foot Mount Washington, Mounts Adams, Jefferson, Monroe and Madison also exceed 5,000 feet in elevation. The Appalachian Trail in New Hampshire runs mainly through the White Mountains, including a section along the Presidential Ridge that is the longest section of the trail above the treeline.
