Pokémon Diamond and Pearl/Route 210

Route 210 is a huge route connecting Celestic Town and Solaceon Town. At first, the path north and west to Celestic Town will be blocked by a pack of Psyduck suffering from debilitating headaches. There is nothing you can do for now, so head east to Route 215.

Wild Pokémon
''Different Pokémon appear on different parts of the route. For the purposes of the wild Pokémon tables, the part of the route below the point where the fog appears will be labeled "Route 210 A" and the part above the fog will be labeled "Route 210 B".''

Note: More Pokémon can be caught by smearing Honey on the golden tree and returning in 12 to 24 hours. If the tree is wiggling, there is a Pokémon inside!

Events
Get TM51 (Roost): Speak to the girl on the ledge above the golden tree. She will give you a TM containing Roost, a healing move for Flying-type Pokémon.

The Café Cabin: The cabin where Route 210 intersects Route 215 has several functions. Here, you can battle several trainers and buy MooMoo Milk for 500.

What To Do For Now: The Psyduck will stay in the same spot until you can find a cure (secretpotion), so there is no way past for now. Head east through Route 215 to Veilstone City.
