Do you want to get Sevii Islands in Pokémon FireRed? Here is all you need to know about it. Follow the steps inside the guide to get to these islands and see what you can find. So, let’s get started.

About the Sevii Islands

The Sevii Islands can be considered the endgame expansion of Pokémon FireRed. Wait for Celio to invite you to this archipelago, which feels like a total tropical getaway, and it’s a good break, to be honest. It’s split into two parts, the first being Islands 1–3, which are accessible early. On the other hand, 4–7 islands open up after you defeat the Elite Four. These islands are utterly important for linking up with the Johto games, and they host unique side quests. These quests include names like the hunt for Ruby and Sapphire plates. If you want a break and a drift through the islands, then this is your opportunity!

Steps to get Sevii Islands in Pokémon FireRed

If you want to get to the Sevii Islands in Pokémon FireRed, then these are the steps that you can follow.

Beat Blaine

In the beginning, you must earn the Volcano Badge from the Cinnabar Island Gym. This is really important, as you will learn a little ahead.

Meet Celio

Once you have the badge with you, you must head to the Pokémon Center on Cinnabar Island. Bill will be there and will invite you to the One Island Pokémon Center to meet his friend, Celio. You must hop along!

The Ticket

Once you accept it, you will travel to One Island on the Seagallop Ferry. Celio will give you the Rainbow Pass, which is your key to accessing islands 1 through 7. Therefore, make sure that you do it well.

The Ruby Quest

To access islands 4–7, you have to complete the main story, which means to beat the Elite Four, and return the Ruby and Sapphire gems to Celio’s network machine.
If you like some post-game treats, then this is something you will probably find well.

What are all the islands in FireRed?

This archipelago is a treat in itself! Let’s break it down to understand.

Islands 1, 2, and 3

These form the “Knotosa” chain and are accessible as soon as you meet Celio on Cinnabar Island.

Islands 4, 5, 6, and 7

These are known as the “Kinna” chain and are locked until you become the Champion and upgrade your Tri-Pass into a Rainbow Pass. Every island is unique, and there will be different surprises on each one of them.

And that is all you need to know about the Sevii Islands and your way of accessing them.
