Remember the boulder? That is an entrance, to which the cave is the exit. So, the cave is the only place any and all of the tunnels and passageways lead to. Since we are heading away from the cave, there are infinite 'exits' to chose from. I have decided this is the best choice, as it is the fastest, farthest, and least guarded entrance. Turning back toward the tunnel, she began to pace downward, glancing back. Any more questions or can we go?
