First you need to have the movie regigigas that was distributed in the debut of the 11th movie. Then, with him in your party, you go to route 228 and you will find a small cave near the exit to route 226 named Rock Peak Ruins. Inside it are a statue and some circles on the floor. Pass through all the circles and talk with the statue and Regirock will appear. The same for the other Regis. Regice cave is in the last part of Mt. Coronet before route 216 (it's named Iceberg Ruins), and Registeel is in the final part of Iron Island cave before the exit (Iron Head Ruins). If you enter in Regirock cave without the movie Regigigas, there will be a Hard Stone. In the Regice cave you will find a NeverMeltIce and in the Registeel cave you find a Metal Coat.
You will find Regirock at rock peak ruins route 228.
