Heading west from Route 130, Route 131 passes by a pair of Trainers (in Pokémon Emerald only) before coming to the mouth of the winding channel that leads to the Sky Pillar. In Pokémon Ruby and Sapphire, there is a female Swimmer west of the channel mouth. In all Hoenn-based Generation III games, there are two more Swimmers to her west.
Northwest of the second Swimmer in this group is a lone Swimmer in the middle of the route. To his northwest is a Sis & Bro Trainer team. South of the duo in Pokémon Emerald is yet another Trainer.
Pacifidlog is a short swim to the west from this point.

However, he informs the player that he cannot allow them entry unless they defeat him in battle again. After he is defeated, he leaves and grants the player access.

Route 131 was first mentioned in Claydol Unleashes, where Professor Cozmo verified the calculations that proved that a giant meteoroid was headed there, threatening to destroy the world if it hit.
The route was mentioned again in PS612 when Ruby instructed Rayquaza to go there.
