In fire red what is the best place to train level 70-80 Pokemon?

Answer 1

I do this all the time trust me this goes quick: Head to seven island and go to sevault canyon keep going toward the tanoby chambers until you reach a house stop there go back up toward the four trainers there is a specific spot where if you use the VS seeker you can rematch all 4 trainers use one of your Pokemon to defeat each trainer and they will level up quick when there weak don't heal them with an item instead go to the house and talk to the guy say yes to his question and your Pokemon are healed then go back and repeat! Or rematch the two trainers right outside of the house each have 6 Pokemon ranging in the high 50's range. Of course the elite 4 is an option i prefer what i just wrote above though.
