Shaymin is at the top of route 224. You need Oak's Letter. After you beat the Pokemon League, go to route 224 with Oak's Letter and talk to him. He will show you the stone tablet and ask you whom you give your thanks to. When you tell him, the ground will change and there will be flowers everywhere. There will be a narrow path up ahead. Then shaymin will appear. Shaymin will look at you, then it will run away. Go down the Seakbreak Path to find Shaymin. (use your bike) Shaymin is located at the Flower Paridise.
There is a road behind the Pokemon league where Shaymin can be found if you get Oak's letter.
