Diglett's Cave is a tunnel in Kanto that goes from Route 11 to Route 2 as a shortcut. Only Digletts and Dugtrios are found in this location. This place is near Viridian City and Vermilion City. The cave's length has fluctuated between games, but during Generation III the cave seemed to be at its longest.
