After you go south through Cycling Road (Route 206), you can cut through some trees and go north to reach Wayward Cave.
Use Flash
The cave is dark, so it helps to have a pokémon that knows Flash. You can get the TM for Flash in Oreburgh Gate (the cave west of Oreburgh City).
Catch Pokémon
In Wayward Cave, you can find Bronzor, Geodude, and Zubat.
Explore the Cave
Go north, then check on the rock to break it with Rock Smash. Then go north from there and check on the rocks to the right to find a hidden Potion. Then go to the left and check on the rock to break it with Rock Smash. Go north from there, then west and check on the rock to break it. Keep going west until the path goes south. At the crossroads, go to the right, then south.
You will find two Hikers that you can either battle separately by talking to them from above, or battle them at the same time by walking between them.

Go back the way you came. When you reach the crossroads, keep going east. You will find an Escape Rope along the path. Go east from there and follow the path. At the next crossroads, go east until you find another Camper and Picnicker. You can either battle them separately talking to them from above, or battle them at the same time by walking between them.

Go north past the crossroads and continue following the path. Eventually you reach a dead end and find Mira, who needs help finding the exit and will follow you. Mira will heal your pokémon after every battle.
Before you leave the area with Mira, check on the rock to the south to find a Nugget.
You won't be able to use an Escape Rope while Mira is following you. Go back the way you came. Here are the correct directions to go at each of the crossroads that you encounter: west, north, and then south until you reach the exit.
