Route 124

Pokémon Emerald guide · Diving and surfing to Mossdeep

Route 124 is a sprawling ocean route connecting Lilycove City directly to Mossdeep City. It features vast deep-water trenches that require HM08 Dive to fully explore, navigate underwater mazes, and locate sunken items. While traveling this route, trainers can also visit the Diving Treasure Hunter's house located on a small island.
