Route 15

Route 15 is a route consisting mostly of water and small islands. Due to the rocks littering the route, Ride Sharpedo is required to fully explore the area, which can be provided to the player by Grimsley, a former member of the Unova region's Elite Four. In Pokémon Sun and Moon, one of the islands has a construction site on it. In Pokémon Ultra Sun and Ultra Moon, the same spot now houses a Mantine Surf Association building. Also in Ultra Sun and Ultra Moon, the player briefly encounters Guzma here during Mina's trial.
