Before you could get round Mirkwood in the North you would be right among the slopes of the Grey Mountains, and they are simply stiff with goblins, hobgoblins, and orcs of the worst description. Before you could get round it in the South, you would get into the land of the Necromancer; and even you, Bilbo, won’t need me to tell you tales of that black sorcerer. I don’t advise you to go anywhere near the places overlooked by his dark tower!
