Where and How to Get into Submerged Island Blox Fruits

In Blox Fruits, the Third Sea introduces new areas filled with stronger enemies, hidden locations, and powerful rewards. One of the more mysterious places is the Submerged Island, a unique underwater island that many players want to explore. If you’re wondering where it is and how to get inside, this guide will walk you through the details.

Where is Submerged Island?

The Submerged Island is hidden beneath the sea of the Tiki Outpost in the Third Sea. To reach it, you cannot simply dive underwater; instead, you’ll need to interact with the Submarine Worker NPC inside Sub Port 01, which is located near the second dock of Tiki Outpost. This NPC will take you into the Submerged Island once you meet the requirements.

How to Enter Submerged Island!

• You must first defeat the Tyrant of the Skies before you can gain access to the Submerged Island.

Without completing this requirement, the Submarine Worker will not allow you to enter. This makes the island more of a late-game area designed for higher-level players.

What You’ll Find Inside

The Submerged Island is designed with a coral-filled, abandoned look. Upon spawning, you’ll appear at a dock with the Submarine Worker NPC.

From there, you can explore structures fused with coral, gigantic clams, and even find a blue chest on top of the highest clam. The left side of the island features a small dock area with barrels and crates, as well as a coral-covered mountain with a cave that connects back outside.

The Secret Cave

Behind two buildings near the Coral Pirates, you’ll notice a cracked stone archway. This looks similar to the entrances for other hidden trials like the Trial of Flames.

While the official method to open this secret cave has not been revealed yet, some players have tried glitching in with Flash Step. Inside, there’s a narrow path leading to a water pool and a den containing a single chest. However, an invisible barrier currently blocks access, suggesting this area might be part of future content.

The Submerged Island is one of the most intriguing areas in the Third Sea, offering unique visuals and secrets for players to discover. To get there, you’ll need to beat the Tyrant of the Skies and then talk to the Submarine Worker at Sub Port 01. While the secret cave remains locked for now, it’s worth keeping an eye on future updates as this area may hide more rewards down the line.
