Choosing where to build your base in Subnautica 2 is one of the most important strategic decisions you will make. A well-placed base provides easy access to resources, safety from leviathans, and a convenient central hub for exploration. A poorly placed base forces constant dangerous travel and wastes time.
The best base locations share these qualities:
- Safety: Away from leviathan patrol routes so you are not ambushed at home.
- Resource access: Near multiple resource-rich biomes including limestone, sandstone, and shale outcrops.
- Depth versatility: On terrain that lets you build shallow with solar power but is close to deeper zones for progression.
- Flat seabed: Smooth ground makes base placement easier and more stable.
- Central position: Equidistant from major biomes so travel time is minimized in all directions.
- Proximity to story content: Near alien ruins or quest zones so you can stage expeditions efficiently.
No single location is perfect -- you will always need to travel for some resources. The goal is to minimize the most dangerous and frequent trips. As a general rule, build your main base in a safe central shallow zone, then establish smaller forward bases or outposts near deep and dangerous biomes as you progress. This hub-and-spoke strategy keeps your main base safe and accessible while giving you staging points for risky deep expeditions.

Top 5 Best Base Locations in Subnautica 2
Here are five excellent base locations that balance safety, resources, and convenience. These are generalized zones rather than exact coordinates, since the alien planet's terrain can vary with updates.
| Location | Depth | Best For | Safety |
|---|---|---|---|
| 1. Shallow Safe Shallows | 0-50m | First base, solar power, starter resources | Very safe |
| 2. Grassy Plateau Edge | 50-150m | Mid-game hub near multiple biomes | Safe |
| 3. Central Kelp Forest Border | 30-100m | Resource access, titanium and copper | Mostly safe |
| 4. Thermal Vent Outpost | 200-400m | Free thermal power, deep staging | Moderate |
| 5. Deep Trench Rim | 400m+ | Forward base for endgame exploration | Risky |
1. Shallow Safe Shallows: The starting zone near your lifepod is ideal for your first base. It is leviathan-free, has abundant starter resources, and sits shallow enough for solar panels. Build here early, then expand or relocate as you outgrow it.
2. Grassy Plateau Edge: The transition between shallows and deeper biomes offers a central position with access to multiple resource types. The flat plateau terrain is perfect for base placement, and the depth is still solar-friendly.
3. Central Kelp Forest Border: Kelp forests are rich in titanium and other metals. Building on the border gives you resource access without the cluttered terrain of the forest interior. Watch for smaller predators but no leviathans.
4. Thermal Vent Outpost: A mid-to-late game forward base near volcanic vents provides free thermal power and staging for deep exploration. The risk is higher, so only build here once you have reinforced vehicles.
5. Deep Trench Rim: For endgame content, a forward base at the edge of deep trench zones lets you restage and resupply near the deepest biomes. This is the riskiest location, so build it last with full hull reinforcements.
Base Location Strategy and Expansion Tips
Do not try to find one perfect base for the entire game. The smartest approach is a network of bases: a main hub in a safe shallow zone and forward outposts near dangerous or deep biomes. This hub-and-spoke strategy keeps you supplied at every depth.
Here are practical tips for base location strategy:
- Start shallow: Your first base should be safe and solar-powered. Do not overthink early placement.
- Build a Moonpool early: Vehicle docking and upgrades are essential, so include a Moonpool at your main base as soon as possible.
- Use beacons: Mark resource nodes, wrecks, and biome entrances so navigation between bases is easy.
- Establish forward bases: A small powered outpost with storage and a Fabricator near deep zones saves round trips.
- Scout for leviathans first: Before building anywhere new, spend a few minutes listening for roars and checking for patrols.
- In co-op, build together: Pool resources for a shared main base, then let individuals build personal outposts.
- Relocate if needed: If you discover your base is too far from key biomes, deconstruct and rebuild. Materials are refundable.
Remember that you can deconstruct base modules with the Habitat Builder to recover most materials. This means your early base is not permanent -- it is a stepping stone. Build functional, upgrade your gear, then establish your ideal base once you know the planet's layout. The best explorers adapt their base strategy as the ocean reveals its secrets.
