Route 128 (Japanese: １２８ばんすいどうSea Route 128) is a water route located in southeast Hoenn. Like Routes 125to 127, Route 128 has many locations where Trainers can Dive to the ocean floor and travel along underwater passages. One such underwater passage near the center of Route 128 continues north into Route 127. The northern terminus is at Route 127. The southern terminus is at Route 129. The eastern terminus is at the location of Hoenn Pokémon League -- Ever Grande City.
This route can be divided into 2 parts. The western part is a north-south route linking Route 127 and Route 129. The eastern part is an east-west channel leading to Ever Grande City. In some ways, this channel can be compared to Route 23 in GenerationsI to III and Route 26 to Route 27 in II and IV.
Route 128 retains the north-south alignment of Route 127 as it proceeds south past a pair of islands with one Trainer each. The route turns to the southeast as it swerves to avoid the top of the Seafloor Cavern. On the east side of the cavern's surface, Route 128 splits into two paths, the main north-south path and an east-west path leading to the base of Ever Grande.
The main path of Route 128 continues southwest from this junction, passing two more islands and a Trainer before turning to the south and becoming Route 129.
Ever Grande connector
To bypass an island located due east of the path's western terminus, the connector heads to the northeast, then to the southeast before taking on an easterly alignment near a large island playing host to a Fisherman. After passing a Triathlete, the path enters the city limits of Ever Grande a short distance to the east.
Underwater
Most of the western portion of Route 128, including the area around the Seafloor Cavern, contains underwater passages that can be reached using Dive. The entrance to the Seafloor Cavern is, fittingly, on the seafloor near the southern terminus of Route 128. North of the cavern, the underwater passage continues onto the floor of Route 127.

Trainers
This section is incomplete. Please feel free to edit this section to add missing information and complete it. Reason: Japanese names
Trainers with a PokéNav by their names will be registered in the Trainer's Eyes or Match Call function after the first battle, and may have a rematch with the player with higher-level Pokémon.

Trivia
It is possible for Cooltrainer Ruben to walk over the spot where a hidden Heart Scale is before initiating battle with him. This prevents the player from acquiring the item until they leave and re-enter the route which resets his position.
