Are you tired of roaming the First Sea and wondering where is the Underwater City in Blox Fruits?
Let this guide serve as your compass.

One of the challenging parts of navigating the First Sea is the large distance between islands with no map to guide you.
The compass is only useful if you have a quest on a certain island. Otherwise, you’ll be groping for directions yourself.
It’s extra hard to find the Underwater City because unlike other islands in Blox Fruits, its silhouette can’t be seen from afar.
In this guide, I’ll teach you how to get to Underwater City in Blox Fruits and give you a map of the First Sea so you won’t lose your way again.
Where Is the Underwater City in Blox Fruits?

The Underwater City in Blox Fruits is located in the First Sea, between the Frozen Village and the Prison.
To enter this submerged island, you need to look for a large whirlpool surrounded by three rocks.
Step into the whirlpool and you will be teleported to Underwater City.
The Underwater City in Blox Fruits is a unique location that can be found under the sea. This underwater island is covered with a dome preventing water from flooding in.
