Take the train to the desert. Go up along the rail until you reach the top left corner of the desert.
Go inside the cave. Use Power Gem in a battle with a wild encounter and end the battle in a Crystal Cavern to make the crystals appear. Activate the red crystal to make the breakable door appear. Break it and go inside.
Use Power Gem and end the battle in a Crystal Cavern again in a battle with a wild encounter to make the crystals appear. Activate the green crystal. Break the rock.
Go back to the previous area, and return. This time, go all the way to the top wall, like in the left photo. Then Use Power Gem and end the battle in a Crystal Cavern again in a battle with a wild encounter to make the crystals appear. The reason you have to do that near the top wall is that you need access to the red crystal near the top wall to proceed, but after the transformation, there will be a rock blocking the way to it. After you make the crystals appear, activate the red crystal, smash the wall, and go in further.
Use Power Gem and end the battle in a Crystal Cavern again in a battle with a wild encounter to make the crystals appear. Activate the green crystal. Break the rock.
Go back to the previous area, and return. Go to the opening in the top right corner of the room. Use Tailwind in a battle with a wild encounter to change the weather into Strong Wind.
Start from the tile above the area. Jump right and down and land on the middle area. 
Jump down and left.
