How do you get into Mt. Silver?

First get all eight badges in Kanto. At the entrance to victory road,the path on the left will be no longer blocked and go through there.And you are in Route 29 (or 28, I can't remember). Just walk through the long grass and you are in Mt. Silver.

You need all 8 badges from kanto I think.

Collect all 8 of Kanto's badges and talk to Prof. Oak. Then you can go to Mt. Silver.

You need to get all sixteen badges to get to Mt. Silver.

Get all 16 badges from kanto and johto and you will get access to mt silver.

get all 16 badges go to professor oak then go to victory road and theres the entry unbloked simple!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I already have all the badges from johoto and kanto region, and I already talked to oak and he says"if I find anything new, i'll tell you." and I still can't get to mt.silver becuzz the guys blocking my way.

You get all 16 badges and then uyou talk to professor oak

You must have forgotten beating a gym in Johto.

After getting the eight Kanto badges, go to Pallet Town and talk to Prof Oak. He'll grand you access. Then go to the Indigo Plateau via Viridian City and the man blocking the way to the left will have moved.

You have to talk to professor oak once you get all 16 gym badges and he will let you into mt. Silver
