“This trail traverses Green Top and Rich Knob then connects to the Mountains to Sea Trail which is closed to bicycles.
— Nora Velp
From Yellow Gap, there are three climbs, the second and third of which are named Green Top and Rich Knob, respectively. Green Knob is a beast that will force you off your bike. The trail joins into the Mountains to Sea trail at the base of Ferrin Knob. It is at this point that bicycles are not allowed to proceed any further in either direction, so you'll have to return the way that you came.
