This is best done in steps.

The Mega Ring upgrade is necessary to find the Gyaradosite and many other Mega Stones, so make sure you do it!2.Make sure the time on your 3DS clock is 8:00 PM - 8:59 PM. If it is not, the Gyaradosite will not appear.3.Go to Couriway Town.If you visit an area that overlooks some of the waterfalls, you should find a sparkling object. It is the Gyaradosite.

Unfortunately you can’t steal Mega Stones, so this is the only way you can get one besides trading.

You can only get it post-game.

You can find it inCouriway Town.Head into the south part of the town and then head to the east where a man is standing in front of a small area of flowing water. In this area you can see three waterfalls, and the Gyaradosite can be found in the middle.

You can only get it between8PM and 9PM and after touching the Sundial, so make sure you do that first.
