Map of Underground Path in Pokémon FireRed and LeafGreen
Underground Path 5-6 (in-game map)

The Underground Path is two short, encounter-free tunnels that run beneath Saffron City: one links Route 5 to Route 6, the other links Route 7 to Route 8. They are mainly a shortcut around the closed Saffron gates, and you can use them any time after reaching Cerulean and Vermilion.

Tips

  • No wild Pokémon appear here, so it is a safe way to cross the map and to heal or rearrange your party.
  • Each tunnel hides seven items that are easiest to find with the Itemfinder, mostly status healers (Potion, Antidote, Burn Heal, Ice Heal, Awakening, Parlyz Heal) plus an Ether.
  • At the North Entrance (Route 5 side) a girl trades Pokémon: in FireRed he swaps your Nidoran♂ for a Nidoran♀ named Ms. Nido, and in LeafGreen he swaps your Nidoran♀ for a Nidoran♂ named Mr. Nido.
  • The north-south tunnel takes you from Cerulean's side of the map to Vermilion City, while the east-west tunnel connects Celadon City to the Lavender Town side.
