Sinnoh Route 212

Route 212 is the longest route in the Sinnoh region. There are two parts of this route, a marsh trail and then a locale next to Mr. Backlot's Mansion.

Description
The marsh part of Route 212 has many trainers, most of them being Poké Rangers and Fishermen. This part has rain most of the time, and it rarely doesn't rain. Only one home resides in this part. The people who live here can trade shards for something in exchange. In D/P, they'll give you a TM. In Platinum, they'll teach a selected Pokémon a move. The list of moves teachable is found in the northern part of the house. The second part of Route 212 resides near Mr. Backlot's mansion. Around the mansion are rich trainers and Policemen.
