Three Isle Port is a small section of Kin Island, which in turn is a part of the Sevii Islands. The port consists of a Seagallop boarding station and dock, also including a small grassy knoll where Dunsparce can be found. A cave between the port and the knoll can not be fully accessible until after the player has beaten the Kanto Elite Four and has the National Pokédex. A gold-seeker inside the cave claims to have discovered the cave and was exploring it for any gold, and when talked to after the player defeats the Elite Four, he will give a player a Nugget.
