4th Gen What part of Sinnoh was your favorite place to train?

[PiPVoda]

Mine for weak (like 35 and below) was route 206 from Eterna and Route 207 (trainers there were good for training). For stronger pkmn I found myself on route 214 from Veilstone. Route 217 was okay too but really getting stuck in the snow got annoying after awhile.

hmm pre E4 was beside sunnyshore after was route 224 and the sandstorm route by the resort area

 

[Toa Hyro]

North of the fight area for battle tower/frontier training.

 

[GoldvsRed]

Route 222 for the trainers there, and Victory Road for the wild Pokemon battles.

 

[Leonardo10]

Anywhere where trainers have Pokemon that are level 55+ actually. Before then I just trained anywhere where they had half-decent trainers.

the sandstorm route by the resort area

This. The Chansey there especially helped with getting some of my lower leveled pokemon to grow.

 

[MaikeruS]

That volcano, uhmm, stark mountain, its good because the pokemon are strong. and you can only get there if youve proven worthy, by beating elite four.

Pre-E4, I would say the Victory Road and that lil pond of water above the waterfall leading to Victory Road.

Post-E4, Stark Mountain, Sandstorm Area, etc... basically just that giant piece of land northeast of the E4 area.
