Things You'll Need
Instructions
Entering the Safari Zone
Go to Fuscia City in the Kanto region by walking or by using the fly ability that one of your Pokemon knows; alternatively you can use the surf ability for traveling with water Pokemon.
Head north of the city and enter the Safari Zone.
Talk to the guy at the entrance and agree to pay 500 Pokemon dollars to receive 30 Safari Balls.
Catching a Pokemon
Walk through grass or surf on water until you find a wild Pokemon.
Throw bait at the Pokemon to make it less likely to run away but harder to catch; throw a rock to make it more likely to run away but easier to catch.
Throw a Safari Ball to attempt to catch the Pokemon; you are unable to weaken the Pokemon since battling with your own Pokemon is not allowed in the Safari Zone.
Continue this process until you've caught the Pokemon you want or all your Safari Balls are gone; if you run out of Safari Balls, exit the Safari Zone and pay another 500 Pokemon dollars to obtain 30 more.
