The area right before Ice Path, as well as Route 45 are sort of good training spots.
of if you have finished the game you can re-battle the elite four.
trade them to heartgold
There really isn't a quick way to get to level 100 fast without cheating. The best way would be to re-battle gym leaders and the elite four, along with wild pokemon. Sorry, you'll just have to be patient.
Defeating Pokemon that are a higher level that it, or Rare Candies.
O.O you can't and why would you want to?
IN MY OPINON master, ultra,heavy,great,net,fast.

Depends on the level of your Pokemon. BUT good places to train are the Elite 4 (Just use type difference to your advantage and WALLAH), and Mt. Silver. If your Pokemon arent up to that level yet, try Ice Path or Victory Road.

Pokemon day care or put exp.share on a weak Pokemon
take them from loest to highest gym leader towns ang they will get to about 60 the take them to mount silver and do it till they get to 100
You can keep beating the league over and over but this will take some time as there are five trainers that will take a while to beat and then you have to watch the credits which is a drag... I trained all my level 100s at mt Silver It takes a LONG time, but is necessary if you want level 100 pokemon (without cheating)
in Pokemon silver you can catch Pokemon as how you catch in other versions. in the Silver version is where the use of special Poke balls were introduced just like Fast Ball, Heavy Ball and Lure Ball.
To get a Pokemon level up quickly is to have a Pokemon hold exp. Share and then just battle a bunch of trainers or wild Pokemon.
