The Dunes is a biome located west from Lifepod 5, on the edge of the map, bordering one of the Grassy PlateausSea Treader's Path, one of the Safe Shallows, both of the Blood Kelp Zones, the Northwestern Mushroom Forest and the Crater Edge.

Wreck 6 is found within the Dunes, having seemingly slid down the sandy dunes from the Northwestern Mushroom Forest. Another two wrecks are also found in the Dunes, this time near the Sea Treader's Path border.

Spoiler alert: The following section contains story related material.

The Dunes also harbors a crater from a meteor impact, which an Sanctuary Cache can be found,and a large sinkhole, which can be found near a Wreck.

An Alien Vent Entrance Point is found in the Dunes.

One of the five Sea Emperor Juveniles can be found here after the Sea Emperor Leviathan Eggs have been hatched.


The Dunes features vast, sandy plains and dunes, sometimes littered with various types of rock structures. It is also home to many dangerous types of Fauna, the most notable one being the eight Reaper Leviathans that patrol the open spaces of the biome.

Gasopods can be found, alongside their eggs, near the several hydrothermal vents in this biome. Most of the Flora and Coral is also located near these, alongside Lithium and Ruby. Reaper Leviathans often wander close to the hydrothermal vents so tread carefully.

Even in the daytime, the Dunes are quite dark and murky, making it difficult to see threats. It is recommended to keep track of where the Reaper Leviathans reside and give those areas a wide berth.

If building a base in the Dunes, a Scanner Room is incredibly useful. Not only can it be used to scan for resources, but it can also be used to keep track of the Reaper leviathans in the vicinity. This is especially effective with a Scanner Room HUD Chip.



  • The Dunes once contained entrances to the Inactive Lava Zone and Lost River. It is unknown why these entrances were removed.
  • The Dunes is the second largest biome in Subnautica, secondary only to the Crash Zone.
