HeartGold & SoulSilver Route 42

Rockfalls and ledges step down the mountain road east toward Mahogany, where one of Mt. Mortar's mouths gapes open partway along.

Route 42 is in Johto, with Mahogany Town to the east and Ecruteak City to the west. In the story it comes after Cianwood City and continues north to Mt. Mortar.
