Mount Lanakila

Mount Lanakila is the tallest mountain in Alola, located on Ula'ula Island. It is located north of Tapu Village and its peak is the site of Alola's newly established Pokémon League. While the area is initially under construction, the construction will be complete by the time the player has ended the situation with Lusamine in Ultra Space or has completed all of their island challenge trials, creating Alola's Victory Road. After the player has completed all of their trials, Nanu / Hapu tells them that in the past, prior to the establishment of the Pokémon League, Mount Lanakila was the location of the final trial, where, similar to the Elite Four, a Trainer had to defeat all four island kahunas in a row in order to become the island challenge champion.
