How do you get into cerulean cave on gold?

Answer 1

You go to the Dragon's Den behind the Blackthorn City Gym, have a Pokemon with HM Whirlpool and HM Surf. I used max repel, because I have higher leveled Pokemon and hate the wild weak ones. You think you can just go STRAIGHT, but DON'T. Because it leads to a dead end. Go to the left or right, and go down and use Whirlpool, then continue and go into the entrance, but before that, SAVE. If you want a good Dratini, answer the questions he asks like this:

What are Pokemon to you?

FRIEND

What helps you win battles?

STRATEGY

What kind of trainer do you want to battle?

STRONG

What is most important for raising Pokemon?

LOVE

Strong Pokemon. Weak Pokemon. Which is more important?

BOTH

If you answer as before, the Dratini you get will have Extreme Speed. The move is good, you'll always go first when you use it, so if you want the Pokemon right away, go to the Dragon's Den with one slot open, and when you finish the test, talk to him again and get it. If not, come back later.

Answer 2

Beat each leader, get the part back to the power plant, and finaly see every pokemon. I don,t know if mewtwo is in the cave because I died.

Answer 3

you can get into the dragon's den when you beat the 8th gym

Answer 4

You can, but i think you must defeat the gym leader first!
