Route 105 (Japanese: 105ばんすいどうSea Route 105) is a north-south water route in southwestern Hoenn. Although it is the fifth route in Hoenn numbering order, it is not the fifth route encountered by Trainers on foot or by Surfing. The only way for a Trainer to cross it early in the game, in fact, is by boat. After the player defeats Norman in Petalburg City and gains the ability to use Surf outside of battle, Route 105 is able to be more fully explored, bringing Trainers in contact with one of the three legendary golems, Regice, in the Island Cave.
Traveling south from Route 104 brings trainers to a rocky sea with six small islands along the western side of the route, one of the islands containing the Island Cave. Trainers who wish to visit the Island Cave cannot Surf straight to it due to a rocky barrier around the small island, and will have to navigate south to cross the largest sand isle; containing a small forest and Ruin Maniac Foster pacing back and forth. In Emerald, west of that isle holds a double battle with Bird Keeper Josue and Ruin Maniac Andres and a hidden Big Pearl.
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.
