Go up when going to Stark Mountian and it is there when going down. It is near a Ace Trainer. :)
If you got the special lv 100 regigigas, go to the route above the resort area that has a sandstorm. There will be a cave there, and if you have Regigigas in your party its eye pattern will appear.
It is in the desert between the Survival Area and Resort area. You have to have beaten the Pokemon league and completed you Sinnoh Pokedex.
You can get a syther above the Resort Area. there will be a patch of grass above the Resort Area.(You have to have a pokeradar)
no regigigas was a new Pokemon in Pokemon platinum
Regirock is in a cave in the sandy part of the Resort area. First you need the special event lv100 Regigigas on your team. If you don't have it, the only way to get one, now, is from the Global trade station (GTS) in Jubilife city.
you can find dustox above the resort area in the grass
Regirock - Above The Resort AreaRegice - Take The Path To The Spear Pillar And You Will See It On Just Before The Cave Exit To The Snowy Area.Registeel - You'll Find it in A Cave On Iron Island. The Cave Is Near The Exit.You Need The Regigigas Form The Pokemon Movie 08 To Get Them.
You can get Regiice in Mt.Coronet. I think Regirock Is In the desert between the resort area and survival area. And Registeel Is at Iron Island. Oh and also you can get it from Pokemon Emerald Version. Hope This Helps
Regirock is not in Mt. Coronet, but on the route above Resort Area, the route with the sandstorm in it. It is reached with the bike and it's entrance is very hard to see within the storm......but you can find it like i did. The only Regi in Mt. Coronet is Regice. Registeel is in Iron Island.
above the resort area which you unlock by getting the sinnoh dex
