Where to find it in X and Y

Match the version, area and method before travelling. Grass, flowers, Horde Encounters, fishing, Rock Smash, ambushes, gifts and the Friend Safari are separate encounter methods.

Rows marked “X only” or “Y only” are version-specific. Friend Safari rows need the postgame Kiloude City safari and a friend whose safari contains this Pokémon.
