The Johto Safari Zone is a special Pokémon preserve where Trainers can capture certain types of Pokémon. The Johto Safari Zone made its debut appearance in Pokémon HeartGold and SoulSilver, where it was shown to be located northwest of Cianwood. It is located at the Safari Zone Gate, a bazaar that sprung up due to the Safari Zone's popularity. It is owned by Baoba, the owner of the former Safari Zone, which was, by then, made into a Pal Park by his son.
For 500, the player will receive 30 Safari Balls. Akin to previous Safari Zones, there is a large area to cover, but the six areas of the Zone can uniquely be rearranged to suit the player. Also, there is no time or step limit to how long the player can try to catch Pokémon. The only ways to leave are to retire, to walk back through the entrance or to run out of Safari Balls.
When a wild Pokémon appears, no Pokémon may be sent out to battle it; catching Pokémon here, as in all Safari Zones, requires sheer luck. There are four options in the battle screen: throw a Safari Ball, throw Bait, run away, and throw Mud. Throwing Bait makes a Pokémon less likely to run, but makes it harder to catch, while throwing Mud does the reverse, making it easier to catch but more likely to run.
Access to the Safari Zone is part of the storyline. When a player first arrives at Olivine City, the Gym is empty. The player must heal the Glitter Lighthouse's sick Ampharos, Amphy, to cause the Gym Leader to return to the Gym. Only then will Baoba phone the player and announce that the Safari Zone is open for business. Players can then traverse Routes47 and 48 to get to the Safari Zone whenever they wish.
