Cerulean City

Cerulean City (ハナダシティ Hanada City) is a city in the Kanto region. It has a few notable locations such as the bike shop and the Cerulean Gym. It is the third major city of the Pokémon Red and Blue and FireRed and LeafGreen series. It is also the location of the third gym/second gym battle. Its Gym leader is Misty. It is located between four different routes: Routes 24, 5, 4 and 9. Its motto is: Cerulean City: A mysterious, blue aura surrounds it in Japanese it is Hanada is the color of Aqua mysteries.

Cerulean Gym
The Cerulean City Gym is located near the northern part of the city. The gym is run by Misty and the primary type is Water.

Bike Shop
Here, you can buy a bike for 1,000,000 (which is impossible as the limit for the player to carry is 999,999 ) or the player can take a Bike Voucher from the Pokémon Fan Club chairman to receive a free bike.

In Generation II, the Bike Shop was closed due to it moving to Goldenrod City. In Generation IV, the building was open, but nothing was in it.

Cerulean Cave
On the Northwestern point of Cerulean City, there's a cave blocked by someone. Beat the Pokémon league (and in the remake beat the Pokémon League and get the National Pokédex and also deliver the ruby and sapphire gemstones to Celio at one island) and you can enter this dark dungeon filled with strong Pokémon. On the bottom floor floats a level 70 Mewtwo.
