Kanto Route 13
From Bulbapedia, the community-driven Pokémon encyclopedia.
Route 13 is south of the Silence Bridge on Route 12. It's a fenced in-maze with many opponents. A small grassy area can be accessed with Cut. There is also some water that connects to Route 12's river areas.
South-west of the fenced-in maze is Route 14, to Fuchsia City.
A Calcium can be found hidden on Route 13.
