Vast Poni Canyon

Vast Poni Canyon is a location on Poni Island in Alola. It connects to the Ancient Poni Path in the south and to the Altar of the Sunne / Altar of the Moone. It is the location of a natural trial site, and in Pokémon Sun and Moon, it is also where the player battles Hapu in her grand trial and meets Mina, the sole captain of Poni Island. The area produces a special magnetic field that allows Magneton, Nosepass, and Charjabug to evolve when leveled up here.
