Vermilion City is a rather large city in the Kanto region. There's a port at the southern edge of town, along with an electric-type Gym, whose leader is Lt.Surge. The HM Move Cut is required to reach the Gym.
The Kanto region's Pokemon Fan Club is also located here. In the first Generation games and their remakes, this is where you receive the Bike Voucher, which allows the player to get a Bike from the Bike Shop in Cerulean City.
Diglett's Cave has an entrance just east of the city.
