Pokémon Ruby and Sapphire/Route 131

Route 131 leads up the ocean town of Pacifidlog. Again, there are trainers here.

It also leads up to ../Sky Pillar/, which is unlocked after beating the Elite Four in Ruby and Sapphire. In Emerald, it is available a bit earlier in the game, after Groudon and Kyogre are awakened and begin fighting in Sootopolis City.
