Pokémon world locations

(Japanese: 地底遺跡 Underground Ruins) is an area located within the Clay Road.

The legendary golems, Regirock, Regice, and Registeel, can all be found here. Which is found depends on various conditions. Regirock is found in the Rock Peak Room once a puzzle is solved, while Registeel and Regice require the Steel Head Key and Iceberg Key, respectively, to unlock the Iron Room and Iceberg Room, respectively. The Iron Key can only be found in Black 2 and the Iceberg Key can only be found in White 2; the key that cannot be found in one version can be sent through Unova Link from another game. If all three legendary golems are caught here and present in the player's party, then Regigigas can be awakened in Twist Mountain.
