All Subnautica biomes – Locations, depths, and harvesting nodes

There’s maybe too much to see and do in Subnautica. So much so, its gigantic map has the potential to feel as if you’re in Castaway, and lost beyond repair. Well, aside from the game’s islands and caves, you’ll want to understand the locations of 15 biomes to make way 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’re headed.

• Depth: 0-500 meters
• Harvesting Nodes: Sandstone and Shale Outcrop

Mushroom Forest

• Location: There are two sections of the Mushroom Forest, each being near the center of the map, divided by the Kelp Forest.
• Depths: 75-250 meters (west region) and 125-200 meters (east region)
• Harvesting Nodes: Limestone, Sandstone, Shale Outcrop, and Purple Pinecone

Safe Shallows

• Location: The Safe Shallows lie in the heart of the map and is inside of the Kelp Forest.
