You cannot find Garchomp, or Salamance anywhere in the wild. You have to get them by evolving their pre-evolved form. You can catch Regigigas at the bottom of the Snowpoint Temple. To be able to awaken Regigigas, you have to have Regirock, Regice, and Registeel in your party. Regigigas will be at Lv. 70, and this is the only time you can catch them.

For a garchomp evole your gible 2 times(you find gible in Wayward Cave under bicycling road,for regigigas migrate regirock regice and registeel to your diamond put them in your party and go tothe snowpoint temple, then press "a" on regigigas statue then just catch it. For salamence migrate a Bagon or shelgon from Pokemon R/S/E and evole them to level 50. Or migrate a salamence from Pokemon ruby sapphire or emerald(R/S/E)

Here are tips on how to obtain them:

1. You must first get Gible, in the secert entry to Wayward Cave, then evolve it to Gabite, then Garchomp.

2. To get Regigigas, you must obtain Regirock, Regice, and Registeel.

3. In Pearl: Go to 210 north and use the pokeradar, to obtain Bagon, then evolve it twice.
In Diamond: Trade or Migrate.

Hope you get them!!!
