There might be too much to see and do in Subnautica. So much so that its gigantic map has the potential to make you look Castaway, and lost beyond repair. Along with the islands and caves in the game, you'll want to understand the locations of 15 biomes for easier navigation. In addition, some spots become incredibly deep dives. So before you put on your virtual scuba gear, make sure you know where you are going.

- Depth: 200-580 meters
- Harvest nodes: Shale outcrop
Bulb area
Image via Subnautica Wiki- Location: Bulb Zone is along the northeast coast, between Crash Zone and the mountains.
- Depth: 140-480 meters
- Harvest nodes: Sandstone and shale outcrop
Rocky field
Image via Unknown Worlds- Location: Crag Field is the southernmost biome and nestled between Grand Reef and Crash Zone.
- Depth: 12-460 meters
- Harvest nodes: Limestone and shale outcrop
Zone de crash
Image via Unknown Worlds- Location: It is the largest of all biomes and occupies most of the Southeast region.
- Depth: 0-370 meters
- Harvest nodes: Limestone, sandstone and shale outcrops
Dunes
Image via Unknown Worlds- Location: The dunes can be discovered by heading to the farthest point in the northwest.
- Depth: 65-400 meters
- Harvest nodes: Limestone and sandstone outcrop
Grand Reef
Image via Unknown Worlds- Location: This medium-sized biome is the most southerly and rests to the left of Crag Field.
- Depth: 150-480 meters
- Harvest nodes: Shale outcrop
Grassy plateaus
Image via Unknown Worlds- Location: Like forest biomes, plateaus are divided into smaller parts and can be discovered in the center of the map.
- Depth: 50-170 meters
- Harvest nodes: Limestone and sandstone outcrop
The forest of varech
Image via Unknown Worlds- Location: The kelp forest, like the grassy plateaus, is divided into sections around the map. Larger areas of it lie mostly in the middle of the sea, outside of the safe shallows.
- Depth: 0-160 meters
- Harvest nodes: Limestone and sandstone outcrop
Mountains
Image via Unknown Worlds- Location: This long area is located at the northeast end, above Bulb Zone.
- Depth: 0-500 meters
- Harvest nodes: Sandstone and shale outcrop
Mushroom forest
Image via Unknown Worlds- Location: There are two sections of the Mushroom Forest, each near the center of the map, divided by the Kelp Forest.
- Depths: 75-250 meters (west region) and 125-200 meters (east region)
- Harvest nodes: Limestone, sandstone, shale outcrop and purple pine cone
Shallow safe
Image via Unknown Worlds- Location: The Safe Shallows can be found at the heart of the map and can be found inside the Kelp Forest.
- Depth: 0-80 meters
- Harvest nodes: Limestone and sandstone outcrop
Sea Treader Path
Image via Unknown Worlds- Location: The path is south of Dunes on the western border of the map.
- Depth: 170-360 meters
- Harvest nodes: Shale outcrop
Sparse reef
Image via Unknown Worlds- Location: This area is south of Blood Kelp Trench and is across from the Grand Reef.
- Depth: 40-310 meters
- Harvest nodes: Limestone outcrop
Underwater islands
Image via Unknown Worlds- Location: It can be found in the far north, between the Northwest Blood Kelp Zone and the Mountain Biome.
- Depth: 35-500 meters
- Harvest nodes: Shale and limestone outcrop
