If if its a lower level like 10-20 you should probably go to the cave on the mountain where you fight team aqua.

Some people will argue with me but i think the best place to train is at the Pokemon lugue you can battle them over and over again
victory road is a pretty good place

In my opinion, Rayquaza is the best! but even if you do not train rayquazaq properly....It might just be a ordinary legendary Pokemon With good skills...............Happy training, people! ^_^
The best way to evolve a Pokemon is to train them often. If they have evolved to their last state then they can't evolve anymore.
find a place that has wild Pokemon the same level as it.
elite 4
ANYWHERE
An area with grass Pokemon would be best.
