Pokemon Emerald: Stuck After Getting the Go-Goggles in Lavaridge Town

Go back to Petalburg City and challenge the Gym there.

Situation#

After getting the Go-Goggles, the desert on Route 111 becomes accessible.

Inside, you can explore the area, battle a few trainers, and sometimes find Mirage Tower, although it doesn’t always appear.

It feels like a new area you’re supposed to explore next.

But even after checking the desert, nothing changes, and there’s no clear way forward.

Petalburg City is where the next major step happens.

This is where the Gym becomes available to challenge, allowing the story to continue.

Go back to Petalburg City and challenge the Gym to continue the story.
