Nimbasa City

After defeating Subway Bosses Ingo and Emmet in a double battle, they will leave. Your partner will then give you the Vs. Recorder.

Head back to the Pokemon Center and take the path north, crossing the bridge.

Immediately north of the bridge, you will see the Big Stadium. You can battle trainers here once per day, but not during event hours.

Next to Big Stadium is the Small Court, which functions similarly with different sports and event hours.

East of Big Stadium is the Musical Theater. You can only enter after defeating Elesa. Walk to your right and talk to the lady along the back wall, next to the Vending Machines, to receive TM49 - Echoed Voice.

Continue west along this strip to reach the gate to Route 5, which has trainers for training before facing Elesa.

Heading east from Big Stadium takes you to the gate to Route 16. Talk to the Black Belt at this gate to receive a Macho Brace. Route 16 has more trainers and leads to Lostlorn Forest.

The amusement park is located near the entrance to Nimbasa City. Enter it and move south off the path to find a Dropped Item.

Return to the path and follow it east, past the Old Nimbasa City Gym. Next to two Vending Machines is a bin where you can find a Revive.

Continue past the Ferris Wheel. When the path turns north, move east onto the grass. To the right of a giant Pokemon statue, you will find a Parlyz Heal.

Return to the Ferris Wheel. The Rondez-View Ferris Wheel offers a daily battle against a trainer whose identity depends on your character's gender and the current season. After defeating the trainer, you will take a ride on the Ferris Wheel.

It is recommended to tackle the Old Nimbasa City Gym, then Route 5 and Route 16, before challenging the New Nimbasa City Gym (Elesa's Gym).

Consider visiting Anville Town if you have spare time and haven't already.
