Vermilion City is located on the southern part of the main area of Kanto. This city has a dock in which you can gain access to the SS Aqua on Wednesdays & Sundays. In addition to that, it houses the Pokémon Fan Club and is where Steven Stone will first encounter you, after you bring power back to Kanto. In the north-east of the city is a building site where an old man and his Machop are building a house.

Gym
The Vermilion City Gym is one of the gyms of the Kanto region. This gym has you activate various switches within bins to try and get to the end, but the location of the switches changes. The second switch is always located next to the first one until you reach the Gym Leader; Lt. Surge. Earning the Boulder Badge does not give access to any hidden moves outside of battle.
