Quick answer
Pick a first base near common resources, shallow return paths, clear sightlines, and at least one safe route into deeper exploration. Do not optimize for beauty before survival.

Tactical brief
How to use this guide in a real dive
Best First Base Location is useful when the player needs a repeatable decision path, not just a short answer. Start with the page objective, then compare the map anchor, the first evidence frame, and the current Early Access status before committing to a longer dive. This keeps the guide practical when Subnautica 2 routes shift between patches.
On the atlas, this guide is tied to First Base Safe Basin. Treat that marker as a route anchor: Early base location anchor for low-risk storage, fabricator access, and visible return paths. The important player action is not simply reaching the dot, but using it to decide when to approach, what to scan or gather, and how to leave cleanly.
The first visual check is Safe starter site (00:52). Use that frame as the reading order for the rest of the article: identify the landmark, confirm the objective, then watch for the mistake that would force a reset. The first base should make returns shorter, not simply look dramatic on the map.

Field manual
Best First Base Location field manual
Built from the supplied route videos and local frame captures so the article teaches what to watch for, not only what to click.
Pick a first base near common resources, shallow return paths, clear sightlines, and at least one safe route into deeper exploration. Do not optimize for beauty before survival. Use this progression route manual as a second-screen checklist: identify the entry condition, confirm the objective with a visual proof point, then stop when the return rule is met. This keeps the article practical for Early Access patches without pretending every coordinate or state is final.

What to watch in the videos
Pause on Safe starter site and identify the landmark, depth band, or objective state before following the next step.
Use Nearby resource lane to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Expansion clearance as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.

Guide notes
The first base should reduce friction
A starter base is not the final headquarters. Its job is to shorten trips, reduce oxygen risk, and make crafting decisions easier.
What makes a location reliable
Good first sites have visible landmarks, safe terrain, repeatable materials, and enough space for later power and storage modules.
Risk controls
Common mistakes
These are the actions most likely to waste oxygen, lose the route, or turn a clean scan into a failed attempt.

Near starter shallows
Approx. 70-120m from pod
Confirm oxygen before leaving the first landmark. The route is much safer when you mark the return path before collecting side materials.
