The path to mount cornet is also the path to hearthome city so you will see 2 doors. One is the city and one is a path to mount cornet.Check them out!
It depens on what Pokemon your talking about. I only know where a few are. Darkri is in the locked door in canalave. Palkia is in the top of mount cornet. Aurceus is also at the top of mount cornet, but you need a auzure flute. You can get that after you defeet the elite 4 at a pokemart.
You can find mount cornet near the battle zone, after you deafeat the ellite four.
