In Blckthorn City
cindber island
Yes.
beat the 8th gym leader and then talk to to professor elm :)
you go to blackthorn city to fight the 8th gym leader
Blue (The eighth gym leader) is waiting on Cinnabar. He won't battle you unless you've beat the rest of the gym leaders
In the original Pokemon Silver you had to beat the 8th gym leader, Claire, then she allowed you to pass.
Blackthorn city, in kanto you find him at cinnibar island show him your 7 kanto badges to make him go back to the gym then you can battle him.
You need to have the HM whirlpool which I belive you get from the 7th or 8th gym leader in Johto
blackhorn city i think its next to mahogany town
Defeat Blue the 8th gym leader in kanto and then go talk to prof. oak. He should give you rockclimb
Well Claire has dragon types so you need Ice types to defeat her.
The answer is simple: defeat the 7th gym leader. That would be Blaine, who is found in the Seafoam Islands. Defeat him to gain access to the 8th.
