I'm at Hearthome City right now, and my starter is Lvl. 27 right now while the rest of my team is in between Lvl. 17-26. Is there a good place to grind for levels anywhere before Hearthome?
I think the best way to grind is the grass before you go into Hearthhome city. You can find the highest Pokemon there based on where you are in the storyline now. I Hope I helped :)
Catch a Buizel at valley windworks and grind it into a floatzel . if you do this you can whiz past the third gym .
