|This article is about the Floating Island. You may be looking for the Mountain Island or the Underwater Islands.|
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 ancient Floaters located underneath the Island.
The Floating Island was also the residence of the Degasi Survivors for a small while. There, they constructed a main base, which has been partially covered by a mudslide. Two smaller observatories doubling as small farms, and a larger farm on the other side of the Island.
The Floating Island is fully explorable and quite 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 Alien Arch 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 Arch inside links to the Mountain Island Arch Cache.
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.
