Route 17 (Japanese: １７番水道Water Route 17) is a route in southwestern Unova, connecting Route 1 to Route 18. It is accessed by Surfing west from Route 1. The player spends most of the time here surfing, although there is shallow water on some parts of the route where the player can land. There are a lot of water currents here, and the water currents going down will lead the player to Route 18.
Route 17 is a mid-sized sea route littered with shallow spots and currents. Because of the currents, a few players may find difficulty in accessing Route 18. The electric billboard inside of the gate from Route 1 to Route 17 is off due to the lack of news in the area. The guide claims it is 'kind of refreshing.'
