Key Highlights:
- Sons of the Forest contains seven named bunkers: Entertainment, Food and Dining, Residential, Luxury, Maintenance A, Maintenance B, and Maintenance C.
- POI laptops reveal bunker locations on the GPS, while Maintenance A, B, and C are buried facilities that require the Shovel to expose their entrance hatches.
- The Maintenance Keycard opens Entertainment and Food and Dining, the Guest Keycard grants access to Residential, and Luxury Bunker must be unlocked remotely from Residential.
Quick Links:
Bunkers in Sons of the Forest form one of the island’s main progression networks. The seven underground facilities contain keycards, weapons, 3D Printers, story material, and access routes that eventually lead towards the endgame.
Since Patch 04, most bunker locations are not simply displayed on the GPS from the beginning. Endnight introduced discoverable POI laptops and computers that reveal additional underground facilities as you explore the island. Some bunker entrances are also buried, making the Shovel essential for reaching Maintenance A, B, and C.
The bunker network is not a single numbered quest chain, so you can discover some locations in a different order. However, keycards and POI discoveries create several important progression dependencies. I recommend collecting the Shovel and Maintenance Keycard early because they unlock access to some of the most useful facilities.
Entertainment Bunker
- Where: Western side of the island, near the forest helicopter crash region
- Access Required: Maintenance Keycard for the main bunker
- Key Items Found: 3D Printer, Guest Keycard, Guitar, Chainsaw, Track Suit
- POI Progression: A computer inside reveals Maintenance B
The Entertainment Bunker is entered through a cave on the western side of the island. Its location is revealed by the POI laptop near the entrance of the Rebreather Cave, while the main secured section requires the Maintenance Keycard.
After passing through the cave-in and utility tunnel, look for the maintenance room marked by yellow construction signage. A 3D Printer, sleeping bag, crafting supplies, and several lore items can be found before the secured entertainment complex.
Use the Maintenance Keycard to enter the main bunker, which opens into gym, spa, pool, nightclub, and lounge areas occupied by mutants.
The Guest Keycard is found inside the nightclub area and unlocks the nearby computer room, as well as another secured section of Entertainment Bunker.
Inside the computer room, interact with the terminal to reveal Maintenance Bunker B on the GPS. Continue exploring the Entertainment Bunker for the Guitar, Track Suit, and the Chainsaw, which is found deeper inside the cinema area.
For the exact locations and access requirements of the Maintenance, Guest, and VIP cards, our Sons of the Forest Keycard Locations guide handles the keycard chain separately.
Maintenance Bunker A
- Where: Western side of the island, beside a river bend inland from the western beach
- Access Required: Shovel
- Key Items Found: Maintenance Keycard, Firefighter Axe, Laser Sight, Tuxedo, 3D Printer
- POI Progression: Contains the GPS location for Food and Dining Bunker
Maintenance A is a buried maintenance bunker, so you need the Shovel before its hatch can be exposed. The digsite sits beside a river that eventually flows towards the western beach.
Once the hatch is uncovered, descend into the compact maintenance facility. The bunker contains several valuable progression items, including the Maintenance Keycard, Firefighter Axe, Laser Sight, Tuxedo, and a 3D Printer.
A residential room inside also provides the GPS information for the Food and Dining Bunker, making Maintenance A an important early link in the wider bunker network.
The Maintenance Keycard becomes especially important because it opens secured sections of both the Food and Dining and Entertainment bunkers.
Food and Dining Bunker
- Where: North-western region of the island
- Access Required: Maintenance Keycard for the deeper hydroponics section
- Key Items Found: Crossbow, VIP Keycard
- POI Progression: Laptop inside reveals Residential Bunker
The Food and Dining Bunker is reached through a cave leading to a hatch labelled for the facility. The entrance opens into food-storage areas filled with supplies before a secured door blocks further progress.
Use the Maintenance Keycard to enter the hydroponics section. Mutants occupy the deeper rooms, while the Crossbow can be recovered during the route through the growing areas.
Further inside, a flooded section contains the VIP Keycard and a POI laptop that reveals another bunker location. The VIP card then opens the dining hall, where the mutated Mr and Mrs Puffton encounter takes place.
Food and Dining therefore performs two progression roles: it provides the VIP Keycard and advances the GPS bunker network.
Residential Bunker
- Where: Eastern side of the island, close to the largest lake
- Access Required: Guest Keycard
- Key Items Found: Katana, Gold Mask, Pistol, Putter, Flashlight Attachment, weapon rails, 3D Printer
- Endgame Role: Contains the control sequence used to open the Luxury Bunker
The Residential Bunker is on the eastern side of the island, near the island’s largest lake. This is an important correction from older guides that place it in the north-west. Current bunker data identifies the eastern lake region as its location.
Enter through the cave leading into the bunker’s utility tunnels. A secured door requires the Guest Keycard, which is normally obtained from the Entertainment Bunker.
Residential is substantially larger than the maintenance bunkers, with several floors of apartments, corridors, surveillance areas, and mutant encounters. Notable equipment includes the Katana, Gold Mask, Flashlight Attachment, Pistol and Shotgun rails, Putter, and a 3D Printer.
More importantly, Residential is tied directly to the late-game route. Luxury Bunker is no longer simply opened with a keycard. Its entrance must be unlocked through the control-panel sequence inside Residential Bunker. Endnight removed the old Luxury Bunker keypad route in Patch 02 and replaced it with this progression dependency.
Maintenance Bunker B
- Where: South-western region, near the crashed light-aircraft area
- Access Required: Shovel
- Key Items Found: Compound Bow, Silencer, 3D Printer
- POI Progression: Revealed from the Entertainment Bunker computer
Maintenance Bunker B is a buried facility located beneath a cannibal settlement near the crashed light-aircraft airstrip. Clear or avoid the surrounding cannibals, then use the Shovel to expose the hatch.
This is a small maintenance bunker rather than the gym-and-spa complex described in some older walkthroughs. That larger facility is the Entertainment Bunker.
Inside Maintenance B, the main rewards are the Compound Bow, Silencer, and a 3D Printer.
The bunker’s GPS location is revealed from the secured computer room inside Entertainment Bunker after obtaining and using the Guest Keycard.
Maintenance Bunker C
- Where: Beside the golf course on the eastern side of the mountain
- Access Required: Shovel
- Key Item Found: Revolver
- POI Progression: Revealed by the laptop inside Maintenance Bunker B
Maintenance Bunker C is another buried maintenance facility. Its digsite sits beside the golf course on the opposite side of the central mountain, not beneath a south-western cannibal camp as the older version of this guide stated.
Use the Shovel to expose the hatch and descend into the small maintenance interior. The primary reason to visit is the Revolver, making Maintenance C an important weapon stop even though it contains far less story content than Entertainment, Food and Dining, or Residential.
A deceased maintenance worker can also be found inside the facility.
Luxury Bunker
- Where: Eastern coast, beyond the central mountain
- GPS Reveal: POI laptop inside Residential Bunker
- Access Required: Entrance must be unlocked from Residential Bunker’s surveillance computer
- Key Items Found: Armour Plater schematic, Shotgun Rail
- Endgame Role: Connects to Hell Cave and the final progression route
The Luxury Bunker is the final major bunker in Sons of the Forest and sits near the eastern coastline beyond the central mountain.
Its entrance cannot be opened directly with a keycard. Patch 02 removed the original Luxury Bunker keypad route, and the door must now be unlocked remotely using the surveillance computer inside Residential Bunker.
Residential also contains the POI laptop that reveals Luxury Bunker’s GPS location, meaning discovering the entrance and unlocking it are two separate progression actions.
Luxury contains the Armour Plater schematic, which is found near the golden door and forms part of the full-release endgame progression involving Ancient Armour and Solafite.
A Shotgun Rail can also be collected inside the bunker. However, the Shotgun itself should not be listed as Luxury Bunker loot because Endnight removed that pickup in Patch 02.
The Pajamas are also no longer found in Luxury Bunker. Their location changed for the full-release version of the game, so older guides directing players here for the outfit are outdated.
Beyond the bunker lies the golden-door route into Hell Cave, making Luxury the final bunker stage before the concluding story sequence.
