It's impossible, my friend. In Pokemon Sapphire the Kanto, Johto, and Sinnoh regions are inaccessible. The above statement is correct. However, you could be talking about the two islands that can be visited. There are only two other 'regions' in Pokemon Sapphire and they consist of a few steps of land. These are accessed when you receive a Nintendo event for a certain Pokemon to be unlocked - either Deoxys or Latios. Those two Pokemon can be caught on their respective islands, which can almost be counted as other regions.
No but i think you can trade it from other Pokemon games

no, but you can migrate it from other games
Light Mountain is not an existing location in Pokemon FireRed. Light Mountain doesn't exist in any other Pokemon media including the movies and comics.
The only way is to trade with someone who has one of the other starters and can trade with firered. I know that leafgreen can and so can another firered
Not regions seen in other games, but you can visit some islands that are introduced in the FireRed and LeafGreen games.
there is only one, whitch is kanto.
Unfortunantly you cant go to other regions in Pokemon diamond and pearl. its not like leafgreen,firered,gold,silver and crystal version where you travel to different regions. You can't, Sinnoh is the only region available in the game.
kanto -- Kanto, with the addition of the Seven Sevii Islands!
No, there are no other regions in Pokemon Diamond.
