1. The Grand Reef Plateau - Best Overall
Looking for the complete package? The Grand Reef Plateau is where it's at. This spot gives you access to multiple biomes within swimming distance, ridiculous mineral deposits, and enough wildlife to keep your bioreactor running forever.
Why We Love It
- Central location - easy access to most biomes
- Abundant Lithium and Gold deposits nearby
- Multiple food sources for bioreactor
- Relatively safe from major leviathan threats
Recommended Gear
Before building here, make sure you've got a Prawn Suit for those mineral extraction runs. A good gaming controller makes the excavation work way less frustrating.
2. Grassy Plateaus Entrance - Best for Beginners
If you're still figuring out which way is up, this is your spot. Shallow waters, plenty of resources, and predators are few and far between. It's basically the tutorial zone with real estate potential.
Why We Love It
- Easiest resource gathering of any biome
- Quick surface access for oxygen refills
- Ample Bulbo Trees for early food security
- Perfect depth for solar panel efficiency
3. Lost River Entrance - Best for Mid-Game
When you're ready to graduate to the big leagues, the Lost River entrance puts you right at the gateway to endgame content. Kyanite? Check. Nickel? Check. Creepy bone structures? Also check!
You'll want thermal power here. Solar panels don't cut it at these depths, and running power cables from the surface is a pain in the gills.
4. Mushroom Forest Edge - Best Views
Let's be real - sometimes you want a base that looks cool. The Mushroom Forest edge offers bioluminescent views that'll make your Instagram followers jealous. Plus, the giant mushrooms are just... chef's kiss.
5. Floating Island Above - Best Strategic Position
Set up shop near the Floating Island and you've got surface access, air Gen access, and perfect solar conditions. It's basically real estate gold if you're into that whole "practical" thing.
6. Mountains Base - Best for Kyanite Farming
Need Kyanite for those endgame vehicles? The Mountains biome has you covered. Yes, there's a Reaper nearby, but if you can handle the commute, the Kyanite veins are worth it.
7. Aurora Wreck Exploration Base
Building a forward base near the Aurora wreck is clutch for those early-game Titanium runs. Just... don't dawdle. The Reapers know you're there.
8. Jellyshroom Cave - Best Hidden Gem
Underrated and peaceful, Jellyshroom Cave offers excellent resources and incredible privacy. Build inside the cave and you're basically invisible to everything outside.
9. Sparse Arctic - Best for Ice
Yes, there's ice. Yes, it's cold. But the unique resources found in the Arctic biome make this a worthwhile location for the prepared builder. Bring a heater.
10. Lava Zone Entry - Best for Endgame
Only for the brave. The Lava Zone entrance is where endgame happens. If you're building here, you probably don't need this guide anymore - but congratulations on making it!

View on AmazonFrequently Asked Questions
What depth is best for solar panels?
Shallow is better for solar - think 0-100m. Below 200m, solar efficiency drops significantly. Consider thermal generators or nuclear for deeper bases.
How do I protect my base from leviathans?
Location is everything. Avoid areas marked as leviathan territories (especially near the Aurora and in the Void). Reinforced walls help, but prevention is better than cure.
Can I build underwater caves?
Absolutely! Caves offer natural protection and often have unique resource spawns. Jellyshroom Cave is a fan favorite.
What's the minimum depth for rare materials?
Kyanite starts appearing around 500m. Nickel and Titanium are more common deeper. For the best haul, aim for 300m+.
