Go to Viridian City then go left to route 22and keep going straight then you will encounter your rival. beat him then keep going your path until you till you reach a big house-like thing. go in and a cop will say "oh, that's the boulderbadge go right ahead" leave the house thing and keep following a path with cops inspecting all your badges. Before the soulbadge cop you will have to surf so bring a Surfing Pokemon. Then after the badge cops you will reach victory road. get through victory road(which is a big cave with about 3 floors) then when your out the league will be right in front of you.
