Thirty Mega Stones, half of which only appear after the League, and only between 8 and 9 PM. Collecting them all takes planning. Here is every stone, its exact location, and a route to pick them all up over two evenings.
Reminder: to see the hidden stones, you must have upgraded your Mega Ring at the sundial in Anistar City, after beating the League, playing at the Battle Maison in Kiloude City and defeating your rival in the city’s park. A hidden stone glows on the ground, and only between 8 and 9 PM, console time.
Five stones are exclusive to each version: Charizardite X and Mewtwonite X, Manectite, Pinsirite and Tyranitarite in X; Charizardite Y and Mewtwonite Y, Houndoominite, Heracronite and Aggronite in Y. For the others, a trade is required.
