Route 15

18 Pokémon can be caught at Route 15 in Alola — highlighted on the map below.

Water and scattered islets make up most of this route linking Tapu Village with Route 16 on Ula'ula Island, home of the Aether House. Rocks clutter the sea, so full exploration requires Ride Sharpedo, granted by Grimsley, formerly of Unova's Elite Four. One island holds a construction site in Sun and Moon; the Ultra versions place a Mantine Surf Association facility there instead, and in those games the player also briefly runs into Guzma during Mina's trial.
