From Bulbapedia, the community-driven Pokémon encyclopedia.
- This article is about the Underground Path in Routes 5 and 6. For the Underground Path in Routes 7 and 8, see Underground Path (Routes 7-8). For the Underground Path in Goldenrod City, see Goldenrod Tunnel.
The Underground Path between Route 5 and Route 6 is located directly underneath Saffron City and terminates just to the north and to the south of Saffron City.
In the games prominently featuring Kanto, the path is the only way to travel between Cerulean and Vermilion until the gatehouses surrounding Saffron are opened with a drink from Celadon City.
The path is a long, dark hallway that travels under Saffron. Despite the cave-like lighting of the path, there is no threat to be attacked by wild Pokémon. Occasionally, by using an Itemfinder, items that Trainers have dropped along the path can be found and retrieved.
Differences among generations
Across all generations, the design is virtually the same, only with updated graphics.
