Route 210 is a route located in the Sinnoh region, connecting Solaceon Town in the south, to Celestic Town in the west, and Route 215 in the east. This route has 2 areas: The southern area, and the northern area. Before the players gets the Secret Potion (known as Secret Medicine in the remakes) from Cynthia, a group of Psyduck blocks the player from entering the Northern Area. The southern area is covered in long grass, making bicycles unusable. The Northern Area is foggy so Defog is useful to clear the fog covering this area, but not mandatory.
