Pokémon Diamond and Pearl/Route 210 south

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.

''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".''
