Route 128 Underwater

Route 128 Underwater is a Hoenn underwater route. There are a few Dive spots that can be used to access from Route 128. However, the main area, which leads to the story-important Seafloor Cavern, can only be accessed from Route 127 Underwater.

Notable miscellanies

Seafloor Cavern

Main article: Seafloor Cavern

Certainly, one of the biggest points of interest from underwater, the Seafloor Cavern is the next story location after completing Mossdeep City‘s gym and accepting Steven’s request. The cavern can however only be entered during that moment, and once the cavern has been completed, it is no longer possible to reenter.
