It is a single-player experience that tends to focus on players gathering resources, building an underwater base, and trying to survive. Today’s guide will take a look at Subnautica best place to build a base.
Since the map is absolutely humongous, there are tons of places where you can build your home base. But I found some places to be better than others in terms of nearby resources and the overall layout of the area.

Subnautica Best Place to Build a Base

Since there are many great places where you can potentially build your base, I’ll tell you about six amazing places. These locations are not in any particular order and are totally up to you where you want to settle down.
Jellyshroom Cave

Tab Biomes
Type Cave
Depth Range 180 - 300 meters
Temperature Range 13.4°C-14.3°C
Biome ID jellyshroom
Harvesting Nodes Shale Outcrop
One thing I absolutely love in games is to stop and take in all the beautiful scenery. Jellyshroom Cave provides just that. An amazing view mixed with tons of loot for you to gather and use. If you add thermal power generators to this area, you’ll have a proper base set up in no time.
You should keep in mind that quite a few crabsnakes are roaming in this area. Make sure to keep your eyes open and eliminate them when you get the chance.
It is at 180-300 meters depth and has a total of four entrances to it. Remember to use the Seamoth to explore this area due to its depth. Otherwise, it can prove quite fatal for the player. You can find gold, diamond, and Lithium in this area just to name a few resources.
Also, this is currently the only location to have large magnetite deposits in Subnautica. If you are farming magnetite, you know where to go. On top of that, it is uniquely different from a lot of other places. The ambiance and the overall sights are a pleasure to look at.
The Floating Island
Tab Biomes
Type Islands
Depth Range Above sea level
Temperature Range 20.2°C-40.9°C
Biome ID Islands
Point of Interest Degasi Seabases
Base 1
Base 1A
Base 1B
Alien Arch Cache
-662 2 -1050
The best thing I can say about Floating Island is that there are close to no predators in this biome. There is a ton of open space for you to build on and expand further if need be. Plan your base layout when getting started so it is easier for you to build it. It is located above sea level and the temperature ranged from 20.2 C to 40.9 C.
This island is habited by various edible plants, like the Lantern Tree, exclusive to this area. Not only is this a beautiful location, the way to reach it is quite fun as well. You can either get here by using the main entrance on the beach or via the underwater entrance located at its center.
The biggest downside of this location is that there are extremely low resources and materials. If you were planning to gather materials in this area, I’m afraid that it is not possible. Bringing your materials is recommended. Make sure that you bring a lot of resources so that you don’t have to constantly swim back and forth just to make your base.
Also, it is close to the Degasi Seabases and has many trees, so gathering food will not be a problem. If you are tired of staying underwater and want to get away from it for a while, building your base here is certainly a good idea.
The Cove Tree

Category Flora
Attitude Non-harvestable
Biome Lost River
Tree Cove
Debug Spawn
Covetree
Music Ghost Tree
This is easily my favorite location for building a base in Subnautica. Not only does this area have tons of materials, but it is also close to the lava zone. The Cove Tree has no predators, so you can road around freely without any fear of getting attacked. On top of that, you have the perfect view of the Cove Tree – which is drop-dead stunning to look at.
However, to get there, you’ll need either a cyclops or a prawn since it is extremely deep. The biggest upside of this location is that it is situated near all of the endgame locations. Setting up a base here is definitely recommended as it can be extremely beneficial.
You will be near the endgame locations, making it easier for you to go back and forth between them. As long as you have the prawn suit, you will have an abundance of resources. However, I recommend building a base here when you are in the late game because it is in between the lost river and the lava zone.
Kelp Forest
Tab Biomes
Type Surface
Depth Range 0 - 160 meters
Temperature Range 24.3°C-27.5°C
Biome ID kelp
Harvesting Nodes Limestone Outcrop
Sandstone Outcrop
Coordinates -306 -51 -57
Point of interest Large Wrecks
Destroyed Lifepods
Kelp Forest Caves Entrance
The Kelp Forest has a phenomenal view. Located near the surface, it is one of the most diverse biomes in Subnautica. This is mostly due to the range of fauna and flora habiting this beautiful location. The area has a distinct green hue in the water, which adds to the already breathtaking atmosphere.
It is an extremely good place to charge up your solar power since it is located near the surface. This makes it one of the most productive biomes of Subnautica. Mostly housing passive life forms such as the Hoverfish.
You’ll usually find the Hoverfish swimming around the Creepvines and they don’t really bother the player. In fact, they are mostly pushing around other fish in the current. However, the location does have a major predator – the Stalkers, which can be quite a pain to deal with as they are quite aggressive.
The reason why it’s such a good location for building a base is that it contains most of the raw materials. You can easily gather all of the required resources from here and build your base without traveling around. You can venture deeper to enter the Dense Kelp Forest where you can find huge metal salvages. Overall, the look of this area is wonderful and is recommended if you are looking for a solar-powered base.
Mushroom Forest
Tab Biomes
Type Surface
Depth Range 125 - 250 meters
Harvesting Nodes Limestone Outcrop
Sandstone Outcrop
Shale Outcrop
As the name suggests, this place has huge trees in the shape of mushrooms. Not only is it extremely unique in terms of looks, but it also allows the player to gather solar power conveniently. Building in the mushroom trees was an incredibly unique experience, and it made building my base super fun.
The view is superb as mushroom trees and various other plants surround you. It is considered a surface-type biome and has a depth range of 125-250 meters. You can find dozens of resources here – all of which are extremely useful. Fun fact; when Subnautica was initially released, the Mushroom Forest was the only place where you could get all three of the Cyclops Fragments.
With that being said, I would advise you to stay clear of the border of this biome because a Reaper Leviathan wanders around here. If you stay away from that small section of the area, you’ll have a fun time building your base and wouldn’t have to worry about big predators. Plus, it is near a warp gate which you’ll need to progress the story.
Grassy Plateau

Tab Biomes
Type Surface
Depth Range 50 - 170 meters
Temperature Range 19°C-27.2°C
Biome ID grassy
Harvesting Nodes Limestone Outcrop
Sandstone Outcrop
Coordinates -692 -101 -48
Point of interest Large Wrecks
Small Wrecks
Destroyed Lifepods
Grassy Plateaus Caves Entrance
Jellyshroom Cave Entrances
If you are looking for a location that is ideal for early game, this is it. This biome has vast open spaces that are perfect for building your base without running into any obstacles. Plus, it’s extremely efficient for solar power as it is located near the surface.
To put the cherry on top, this biome is situated near tons of wrecks that you can salvage and stock up on resources. There are also thermal vents nearby so if you are determined enough to take a wire from the Jellyshroom Caves, this is the ideal location for you. A few dangerous predators are lurking about so always keep an eye out. Newer players are advised to always look at their surroundings and stay away from the sand clouds because that means a Sand Shark is nearby.
Resources are abundant in this location and you can find almost every basic raw material. This is the best location for an early game base building as you have access to every necessary resource since the start.
Parting Words
These are the six major places that, in my experience, are ideal for building your base. They not only provide you with great resources but also are situated near important story events that you must do to progress. Some of these locations are best for the early game, whereas others are good in the late game. Give them a try to find out for yourself how effective and useful these locations are to build your base.
