Fallout 4 Vault Locations: Complete Commonwealth Guide

Introduction

If you’re diving into the Commonwealth and searching for fallout 4 vault locations, this guide will walk you through the Vault-Tec mysteries, map tips, and practical strategies for finding and exploring vaults. Vaults are central to Fallout 4 lore: they contain memorable quests, unique loot, terminals filled with secrets, and the distinctive Vault-Tec design you’ve come to expect. Whether you’re hunting for Vault 111 where the game starts, the occupied Vault 81, or other hidden vaults, the tips below will help you locate them, understand their stories, and make the most of each visit.

Understanding Vaults in Fallout 4

Vaults in Fallout 4 are not just set dressing — they are designed as micro-experiments by Vault-Tec. Some are open and populated, others are derelict or sealed. Knowing how Vaults work will improve your ability to find them and extract maximum rewards.

• Vault design and purpose: Vaults were meant for survival and social experiments. Expect terminals, security doors, and interior levels instead of surface landmarks.
• Types of vaults: Occupied vaults (like Vault 81), sealed cryo-vaults (Vault 111), and ruined vaults used as hideouts or labs. DLCs can introduce additional vault-like locations.
• What you’ll find: Terminals with lore, chem labs, unique items, radioactive areas, and occasionally NPCs with quests or trading options.

How to Find Vaults: Tools, Map Tips, and LSI Search Strategies

Finding vaults is part detective work, part in-game exploration. Use these practical methods to track vault locations across the Commonwealth.

• Use the in-game map: Vaults often appear as unnamed structures or are hinted at by nearby named locations. Zooming and scanning the Commonwealth map helps.
• Follow quest markers and rumors: Many vaults are tied to quests or holotapes that hint at coordinates. If a terminal mentions a vault, note the nearby town names or landmarks.
• Read terminals and holotapes: NPC notes and terminal entries often reveal vault maps or access codes.
• Search for Vault-Tec signage: Vault-Tec logos near buildings, maintenance shafts, or fenced complexes are great indicators.
• Use companions and perks: Some companion dialogue or Science and Lockpicking perks make accessing sealed sections easier.
• Check online vault locations map resources: If you prefer a visual approach, community-created vault locations maps can save time.
• Mods and console commands: For PC players, mods or console cheats instantly reveal vault coordinates, but use them carefully if you want to preserve discovery rewards.

Notable Vaults You Can Explore

Below are some of the most memorable vaults you’ll encounter. I focus on the ones that are reliably in the base game and the kind of content you can expect when exploring them.

Vault 111 — The Cryogenic Entrance

Vault 111 is where Fallout 4 begins and is a vital story vault. It’s unique because it’s a cryogenic vault that ties directly into your origin and the main narrative. Key points to remember:

• Location hint: Vault 111 is accessed during the opening sequence in the area around Concord and the Sanctuary region.
• Why it matters: Vault 111 contains the cryo pods and sets up your quest to find Shaun. There are terminals and logs that explain the vault protocols and experiments.
• Exploration tips: Take time to scan terminals and read holotapes for story details. The sequence is mostly scripted, but returning later can reward you with additional loot or context.

Vault 81 — A Living Vault

Vault 81 is one of the most interactive vaults in Fallout 4. It contains a functioning society and multiple side quests. You can trade, take on tasks, and uncover secrets.

• Location hint: Vault 81 is hidden under a clinic area and is accessible without destroying the town above.
• What to expect: NPCs, merchants, a resident doctor, and quests that reveal Vault-Tec’s ethical compromises. Vault 81 also offers unique items and community-building choices.
• Tips: Be ready for dialogue-heavy exploration. You can gain faction standing and special rewards by helping residents.

Other Vaults and Hidden Vaults

The Commonwealth contains other vault sites: some are fully explorable, others are references or partially sealed. Fans frequently search for vaults like Vault 95, Vault 75, and Vault 114. While some of these might be more prominent in fan sites, mods, or DLCs, the base game includes a mix of ruined and intact vault complexes you can investigate.

• Sealed vs. accessible: Some vaults are sealed and require a key, quest, or a script sequence to open. Look for terminals to power doors or find keycards.
• DLC vault-like locations: Far Harbor and Nuka-World expand Vault-Tec lore and include additional vault-style structures and experiments.
• Community discoveries: The map is full of small vault-like ruins where hazards, loot, or leftover tech provide minor rewards.

Practical Vault Exploration Tips (Loot, Radiation, and Terminals)

Exploring a vault is different from raiding a raider camp. Vault interiors are often maze-like and can contain traps, radiation pockets, and locked doors. Here’s how to be prepared.

• Bring RadAway and Rad-X: Many vaults contain radiation hotspots and malfunctioning systems.
• Save often: Vault exploration can trigger scripted events and tough encounters — save frequently to avoid losing progress.
• Hack and pick locks: Invest in Science and Locksmith perks to access terminals and secure rooms full of loot and holotapes.
• Read terminals: Terminals provide lore, access codes, and sometimes reveal nearby vault locations. They also often grant caps, schematics, or initiation data tied to quests.
• Search for unique loot: Vaults commonly house unique weapons, power armor parts, and schematics. Check containers, corpses, and locked safes.
• Watch for environmental puzzles: Some vaults require rerouting power or activating generators to open doors.

How Vaults Tie Into Quests and Settlements

Vaults often intersect with Fallout 4 quests, companions, and settlement building. They can be sources of materials, NPCs, or even potential settlers.

• Quest hooks: Many main and side quests lead you to vaults or require information found inside terminals.
• Companions: Some companions have background dialogues that reference Vault-Tec or help identify potential vault locations.
• Settlements and resources: Vaults can provide rare crafting materials and schematics used in settlements and power armor upgrades.

Common Mistakes and How to Avoid Them

Players often miss vault rewards or get stuck because of avoidable mistakes. Here’s how to make your vault runs smoother.

• Rushing through terminals: Don’t skip logs — they often contain maps and codes.
• Ignoring side doors and maintenance shafts: Vaults are built with multiple access points. Secondary doors sometimes bypass traps or locked main halls.
• Not preparing for radiation: Many vaults have lingering radiation. Bring protective gear and stimpaks.
• Failing to explore thoroughly: Loot can be tucked into side rooms, under floors, or inside overlooked safes.
