And that's just on easy difficulty!
Also, there's a trainer called "Cal" in viridian city that you can battle once a day, He's very strong and gives a huge amount of XP and moneyzzz (Specially on hard diff)

If you can get through Twirl Forest and survive its surprise, you're set on EXP. Also, it depends on how many gym badges you have.
