Start by passing the closed gate and heading up the orange blazed FS road that is part of Massanutten Trail. In 1.1 miles cross Little Passage Creek then in another 0.9 miles orange blazed Massanutten Trail will turn left. At this point you can either continue straight on the FS road or take the orange blazed Massanutten Trail left. They both meet on the other side of the reservoir in 0.6 miles.
After the trails meet and the FS road once again becomes the orange blazed Massanutten Trail continue for 0.3 miles and arrive at the intersection of the blue blazed Tuscarora Trail.
Turn right on the blue blazed trail immediately crossing Little Passage Creek and climbing Green Mountain, arriving at the ridge and intersection of the Meneka Peak Trail in 0.8 miles.
Turn left on the white blazed Meneka Peak Trail where the ridge line gradually ascends then descends to meet up with orange blazed Massanutten Trail in 1.0 mile.
Turn left on the orange blazed trail (also yellow blazed as the Signal Knob Trail) winding around Green Mountain and passing the transmission tower in 1.0 mile. Continue straight crossing the FS road (this is the same FS road you followed up in the beginning of the hike) and in 50 yards reach Signal Knob Lookout.
Return to the FS road turn right downhill and in 1.3 miles arrive back at the intersection of the Tuscarora Trail you took earlier. Continue straight on the orange blazed FS road retracing your route and arriving back at the parking area in another 2.0 miles.
