HeartGold & SoulSilver Mt. Moon

The old cave road tunnels through the hills east of Pewter, where Clefairy still gather under the moonlit cracks in the ceiling.

Mt. Moon is in Kanto. In the story you arrive from Route 3 to the west and continue east to Route 4.

MT. MOON MAP

Mt. Moon is down to one short pass between Route 3 and Route 4, Mt. Moon Square open to the sky overhead and nothing left of its former labyrinth.
