The true summit of Duncan Knob is a nondescript point in the woods in George Washington National Forest. It is situated on one of the smaller ridges in the northern part of the Massanutten Mountains. However, Duncan Knob is still frequently visited (although not as much as Shenandoah National Park) because of the spectacular views from an overlook near the summit. It is also the only peak in the Massanutten Mountains that requires a Class 3 scramble to reach the summit.
From the overlook, views to the east include the main eastern Massanutten ridge and the Blue Ridge Mountains. To the west, views include the main western Massanutten ridge, Short Mountain, and the Shenandoah Mountains. To the south, Strickler Knob and Big Mountain can be seen.

When to Climb
Duncan Knob can be climbed nearly all year round. Fall colors are at their peak in mid to late October. Summer is the worst time for mosquitoes, ticks, and other hostile little critters. The heat and humidity are also at their worst in summer, and views tend to be more limited by haze. The best time for a summer hike is early in the morning.
Hiking should be avoided in the National Forest during the period in late November when it is permissible to hunt deer with modern firearms. In 2017, deer season runs from November 18 through December 2.
