The Floating Island is a unique island biome in Subnautica. It is located towards the southwest of the Aurora. It is a large landmass completely supported by giant Floaters located underneath the Island.

The Floating Island was the rendezvous point for survivors of the Aurora. However, only two made it: Second Officer Keen, and CTO Yu. Keen left behind a signal for the rendezvous point at Lifepod 19.


The Floating Island is fully explorable, and very hot, the temperature on this island reaches upwards of 40°C. The island boasts a grand variety of colorful, terrestrial flora that covers most of the Island's surface. It can be accessed from one the main beach or via the underwater entrance at its center. The Island is a good source of edible plants, namely the Lantern Tree, Marblemelon, and Chinese Potato, which are exclusive to this Island and can be found in various abandoned growbeds.

The Floating Island Warp Gate Cache can be found in a large cave near the centre of the Island. It has two entrances. The first is a little inaccessible. It can be found on a small ledge just above the large lake in the middle. The second is found in a small lump in the ground. This one is much easier to access but harder to find. The Warp Gate inside links to the Mountain Island Warp Gate Cache.

Lithium crystals, along with salt deposits can be found scattered across the Island.

There are also three abandoned seabases built by the survivors of the Degasi, one located at the center and one on each of the mountains of the Floating Island. To reach the two mountaintop seabases, follow the left fork on the dirt path near the beach. The path will fork again before a bridge crossing, with each fork leading to one of the two mountaintops. To reach the central seabase, take the right fork near the beach and follow it around the edge of the Island (It is also possible to simply climb down from one of the mountains to the central seabase). An abandoned farm constructed by Bart Torgal can also be found here next to a naturally made land bridge. It consists of Chinese Potato Plants and Marblemelons.
