You know in victory road there's that one passage that's blocked by the old guy? Well after you've completed the national pokedex he moves away and you go up the path that happens to be in the sea. You find Arceus at the end of it.
Seabreak Path wasnt available in Diamond Pearl or Platinum (maybe it was) but now you have to hack to get there, good luck!
North of the Pokemon league (Take the seabreak path)
There is a Shortcut way Turnback Cave. You go to Seabreak Path and there two way road. One leads to Turnback Cave while the Other leads to Flower Paradise which is the way you straight.
Shaymin can be found on Pokemon Diamond, Pearl and Platinum in the Flower Paradise. Flower Paradise is in the most North Eastern part of the map at the end of Seabreak Path. This area can only be accessed with Oak's Letter which is an event exclusive item.
You will need to use the Action Replay and walk/run with the walk-through-walls cheat enabled to Flower Paradise, which is north of Seabreak Path. Shaymin can be encountered at the ending of Flower Paradise at level 30. You can also trade for it as well with a friend.
OK, I'll answer since I have Shaymin on Diamond. You have to go to Route 224 and find a special rock. My friend said that you need to press A on that rock and it asks you who your friend is. Then, it walks behind you. If you press A on that special rock and it says that it is polished like a mirror, what I did was that I walked north from that rock. You come across a path called Seabreak Path and you run north until you reach Flower Meadow. Walk up the steps, and there's Shaymin!
Get Oak's letter and run across Seabreak path until you are in Flower Paradise and talk to Shaymin battle and Catch it if you like.

i think you need an action replay but i don't have one soo...
When you come to route 224 (Proffeser Oak wants you to in Oak's letter) you can thank anyone you want. It doesn't matter. After that, shaymin appears, and you chase her down seabreak path. Make sure your Pokemon isn't a high level, though. Shaymin is level 30. Hope this helped! ( P.S: use your bike on seabreak path, it's LONG!)
The best way to hatch Pokemon eggs is to cycle from solaceon town to twinleaf town and back .Or cycle up and down seabreak path
you must get oaks letter then go to route 224 where you will meet oak. he will tell you about the large rock on route 224 then ask you to put who your thankful for. suddenly seabreak path will appear.
The island to the right is where you can catch Shaymin. The one in the southeast is Seabreak Path. The one in the east is Flower Paradise, where you can catch Shaymin.
Press L and R to get the Oak's Letter, which activates the Shaymin event in Seabreak Path. 94000130 FCFF0000 B2101D40 00000000 0000B5D4 00000009 D2000000 00000000
You need the cheat "Walk through walls" to pass over the water. Then you are on the Seabreak Path, you have to ride till the end, there you find Shaymin and you can battle against him.
You can find him if you trigger the Shaymin event, where he asks you to write down the name of a trained that inspired you to open Seabreak Path, which leads to Flower Paradise, where you catch Shaymin.
get the mystery gift and go to any pokemart you will see a green guy talk to him and then go to the top of route 214 talk to professor oak then go through seabreak path. hope this helped :)
