At what point of the game can a player access white forest/black city?

Question

How many gym badges would I have, before/after the league, etc.
I ask because I'm considering choosing white to get some interesting potential team-members there, but if it can't be reached until the post-game I'd like to know.

So what is the minimum amount of badges you would have to have by the time you get there?

Answer 1

You have to defeat the Pokémon League to access Black City/White Forest. It is part of the Unova region's post-game content. I'd be careful getting there though, as the trainers surrounding and in the place are all high-leveled.

In that case, I don't really care about them for my challenge run.
