If you exit the hatch and turn around the corner to your left, you will find more salt around the cave’s exit. There also happen to be two pieces of sulfur that don’t require a heat adaptation here.

The best salt farming location in Subnautica 2

To reach the best salt farming location in Subnautica 2, you need the heat tolerance adaptation. To get it, keep following the game’s “main story” by chasing new signals and interacting with every blackbox. Once you’ve obtained a sonic resonator and used it to cure the Angel Comb (starting at the Wander Blackbox), place your hand on the pick flower to unlock heat tolerance. This is the third adaptation you’ll receive, following pressure tolerance and digestion.

So, with heat tolerance unlocked, go to Chap’s Blackbox as described above, but from there, swim toward the northeast. After about 100 meters, behind the human-made items, you can spot two large salt crystals on the seabed. Use the sonic resonator to break them and collect about five pieces of salt per deposit.

From there, continue north-northeast along the seabed to find a third salt deposit, then pivot north to the large Coral Crabs. There, turn north-northeast again to find an additional four salt deposits on the ocean floor. You should have about 35 pieces of salt once you’ve broken every salt crystal in this area.

Best late-game salt farming spot in Subnautica 2

After investigating the Tadpole Pens and crossing the ravine leading to the Alien Ruins, you might be looking for a local salt farming spot. Don’t worry, you don’t need to travel back; there’s an excellent salt farming route just north of the Alien Ruins signal (1,280 meters east of the Lifepod). Starting from the signal, go to the high rock formation in the north-northwest, where you’ll find four salt deposits at the foot of the hydrothermal vent.

If you look down toward the northwest, you’ll spot another two salt deposits on the edge of the cliff (100 meters northwest of the Alien Ruins signal). If you continue north-northeast from there, diving to a depth of 215 meters, you can spot a small chasm surrounded by short, red plants; there are three more salt deposits inside this cave. The last location is exactly 200 meters north of the Alien Ruins signal.

Salt deposits don’t respawn, but once you’ve collected some atacamite, troilite, and axum bacterial cultures, you can craft a metal farm to produce unlimited salt at your base.
