Can you get Riolu before defeating the Elite 4 in Pokemon Sun and Moon?

Question

How to get into Poni Garden? Do I have to defeat the elite 4 and the champion to enter it?

Answer 1

Nope.

Riolu is only available in Poni Grove, which is only accessible post-game.

Hope I could help!

Answer 2

You could easily get one in the GTS until you can access Poni Grove.
