Where to Find Sulfur in Subnautica 2
Complete guide to finding Sulfur in Subnautica 2 — best biomes, locations, and how to farm this essential crafting and acid-production resource.
Sulfur is a critical resource for acid production, propulsion, and certain explosives in Subnautica 2. With 241 known deposits, it is reasonably common but concentrated in specific biomes.
Why You Need Sulfur
Sulfur is required for:
- Strong Acid — Advanced crafting material (with Rotting Jellyfish Cysts)
- Propulsion Cannon — Vehicle and equipment propulsion systems
- Explosive materials — Certain demolition and mining applications
- Chemical production — Advanced laboratory equipment
- Bleach — Water purification tablets
Best Biomes for Sulfur
Sulfur deposits are bright yellow crystalline nodes, impossible to miss:
- Thermal vent areas — Sulfur forms around geothermal vents
- Volcanic rock formations — Heat-altered rock near volcanic activity
- Deep cave systems — Lower cave levels with mineral-rich walls
- Acidic pools — Pools with discolored water often have Sulfur deposits
- Geode formations — Sulfur crystals inside cracked geodes
How to Identify Sulfur
Sulfur is unmistakable — bright yellow crystalline formations that glow slightly when hit by light. Unlike other resources, Sulfur often forms in clusters of smaller crystals rather than single large nodes.

Efficient Sulfur Farming Route
- Locate thermal vent areas in deeper water
- Search the perimeter of each vent for yellow crystal clusters
- Check volcanic rock formations and deep cave walls
- Explore any areas with discolored water or acidic pools
- Collect 10-15 Sulfur per 15-minute thermal zone exploration
Expected yield: 10-15 Sulfur per 15-minute thermal zone run.
FAQ
