The best secret locations in Sons of the Forest are the ones that change your route through the island: the Shovel cave unlocks buried caches, the Maintenance bunkers reveal the facility’s real purpose, and the Luxury bunker leads to the Golden Armor and the final descent. Add the golf course, Timmy’s drawings, the Artifact, and a handful of environmental jokes, and you have a game that rewards curiosity far beyond its GPS markers.
This guide focuses on secrets you can actually reach on Steam, not random map rumors or outdated launch-day discoveries. Cave layouts, bunker access, and item requirements can shift between patches, so check the current official Steam page if your build behaves differently. Before heading out, save at a tent, carry meds and a lighter, and remember that caves often become much more dangerous on the way back out.
1. The Shovel Cave Is the Island’s Biggest Progression Secret
The Shovel cave is easy to mistake for optional exploration, but it is one of the most important locations in the whole game. You’ll find it west of the snowy mountain region, near a small body of water and a cluster of dead cultists. Three bodies hang around the entrance, and their gear tells you the intended solution: this cave expects equipment from other caves first.
Bring the Rebreather and the Rope Gun. The Rope Gun comes from the cave system on the island’s western side, while the Rebreather is found in the large coastal cave farther north. The Shovel cave combines both requirements. You’ll zip across deep chasms, swim through flooded tunnels, and squeeze through passages where mutants can attack from almost no angle.
What to collect before entering
Take a modern axe or better, a crossbow or shotgun if you have one, several grenades, crafted spear ammunition, and enough food for a long run. The cave contains numerous mutants, including babies that can swarm you while you’re trying to climb or swim. Armor is more valuable than carrying a second novelty weapon here because the tight corridors make dodging unreliable.
Once you reach the deepest section, the Shovel is lying beside a body. That single item unlocks the next layer of the island’s secrets: buried Maintenance hatches, the Entertainment bunker route, and several GPS markers that were previously impossible to investigate. Don’t leave immediately. Search the nearby bodies and side pockets for ammunition, explosives, and supplies before starting the return trip.
| Requirement | Where to get it | Why it matters | Best preparation |
|---|---|---|---|
| Rope Gun | Western cave system | Crosses the cave’s vertical gaps | Bring spare ammo and armor |
| Rebreather | Northern coastal cave | Allows the underwater sections | Carry medicine for the exit fight |
| Shovel | Deep Shovel cave chamber | Opens buried hatches and graves | Clear the cave before backtracking |
That progression loop is why the Shovel cave is more important than most surface landmarks. If you’re confused about what to do next, don’t randomly clear every GPS dot. Follow the equipment chain. It’s the cleanest route through the game.

The Maintenance bunkers are more than loot rooms. They’re the clearest evidence that the island was a planned luxury development before the disaster turned it into a nightmare. Use the Shovel at the buried hatches marked by green GPS circles, then search every bedroom, office, bathroom, and storage closet rather than sprinting straight to the obvious item.
Maintenance A and the first major reward
Maintenance A contains the Firefighter Axe, one of the strongest early chopping tools, along with a 3D printer and a keycard trail. The printer matters because resin lets you make arrows, masks, grappling hooks, and other utility items without waiting for a rare surface pickup. Printer resin is limited, so prioritize arrows and the flask before decorative items.
The bunker also introduces the dead-end corporate luxury that defines the island. You’ll find food, printed documents, beds, and personal rooms that look perfectly normal until you notice the damage and bodies. These spaces reward slow searching: supply shelves, open drawers, and bathrooms often contain medicine, ammunition, or story props that disappear into the clutter if you rush.
Maintenance B, C, and the keycard chain
Other Maintenance bunkers contain the Maintenance Keycard, the VIP Keycard, and clues pointing toward the deeper facilities. You don’t need every bunker to finish the game, but exploring them in sequence makes later doors less confusing. The cards are not interchangeable: a VIP door won’t open just because you found a generic guest card.
Keep a screenshot of your map or mark cleared bunkers with custom GPS trackers. Green markers can remain visible even after you’ve emptied a room, and that creates unnecessary backtracking in multiplayer. The official Endnight Games website is also worth checking after major patches because bunker behavior and story details have changed during Early Access.
| Location | Key reward | Hidden value | Recommended timing |
|---|---|---|---|
| Maintenance A | Firefighter Axe, 3D printer | Early tool upgrade and printer access | After getting the Shovel |
| Maintenance B | Maintenance Keycard and supplies | Starts the facility access chain | Mid-game exploration |
| Maintenance C | Story items and bunker loot | Connects the surface clues to the facilities | Before late-game bunkers |

3. The Luxury Bunker Leads to the Golden Armor
The late-game Luxury bunker is one of the easiest secrets to misunderstand. It sits near the eastern side of the island and is tied to the VIP access route, but the real reward isn’t just another room full of ammunition. Deep inside, you’ll find the Golden Armor, the Golden Mask, and the route toward the ending area.
Bring the Guest Keycard and the VIP Keycard, plus a weapon that works in close quarters. This bunker is packed with rooms, bodies, locked doors, and dramatic environmental storytelling. The Golden Armor is found on a body in a ceremonial-looking chamber. Equip it from your inventory; carrying it is not enough for the late-game door sequence.
The Golden Armor’s value is mostly progression rather than raw combat power. It isn’t a magic upgrade that lets you ignore cannibals, and it won’t make a bad fight safe. Its purpose is to interact with a specific late-game door connected to the strange geometric structures beneath the island. Keep it equipped when testing locked story doors, because swapping armor at the wrong time can make you think the item is bugged.
Golden Mask versus Golden Armor
The Golden Mask is primarily connected to cannibal behavior and presentation, while the Golden Armor is the critical story item. The mask can help you move through certain encounters with less immediate hostility, but it’s not a substitute for stealth, distance, or a clean escape route. Cannibals can still become aggressive after an attack or if you enter their territory too carelessly.
If you want a second opinion on hidden-reward design, Steamoz’s secret locations guide for Eternal Destiny covers the same satisfying style of exploration: follow environmental clues instead of treating the map as a checklist.
| Item | Primary function | Common mistake | Practical advice |
|---|---|---|---|
| Golden Armor | Opens the late-game story route | Assuming it is mainly defensive gear | Equip it before testing the final doors |
| Golden Mask | Can influence cannibal encounters | Expecting complete immunity | Use it with stealth and escape space |
| VIP Keycard | Opens high-security facility doors | Trying it on every locked door | Track card-specific routes on your map |
4. The Golf Course Is a Giant Environmental Joke
On the northeastern side of the island, you’ll find a full golf course complete with golf carts, sand traps, flags, scattered clubs, and abandoned development equipment. It’s one of the funniest secrets in Sons of the Forest because the game places an absurdly polished resort project beside one of the most hostile wilderness zones imaginable.
The course is also useful, not just funny. Search the carts and nearby structures for supplies, and look for the Putter and golf balls. The putter is a genuine melee weapon, although it’s more entertaining than optimal. Its short reach and modest damage make it a poor replacement for the Modern Axe, Katana, or shotgun, but it’s perfect for a self-imposed challenge run or a multiplayer bit when your group has already overstocked on ammunition.
Look closely at the surrounding terrain. The course helps explain why the island has so many roads, bunkers, and artificial clearings. This was not merely a random wilderness map with a few labs dropped onto it. The corporate plan was enormous, expensive, and deeply irresponsible. That contrast is the joke: the apocalypse didn’t interrupt a humble campsite; it interrupted a doomed resort project.
There are also small visual gags scattered around the island, including golf-related props and discarded construction equipment. They don’t unlock a quest or improve your stats, but they reward the same habit that finds bunkers: investigate anything that looks too deliberate to be natural.
5. Timmy’s Drawings and the Artifact Connect Both Games
The most important Easter egg is hidden in plain sight through documents, drawings, and imagery connected to Timmy LeBlanc. If you played The Forest, you’ll recognize the connection immediately: Timmy’s survival, his research into the supernatural, and the strange artifacts from the first game all feed directly into the sequel’s mystery.
Search bunkers and story facilities for children’s drawings, photographs, computer screens, and notes. Some images look like simple background decoration until you compare them with the events of the original game. Timmy’s sketches show that the island’s supernatural problem isn’t isolated to one incident. The corporations involved have been tracking alternate dimensions, resurrection, and artifact activity for a long time.
The Artifact and the hidden ending route
The Artifact is one of the strangest late-game discoveries. It is not a conventional weapon, and its function becomes clearer when you experiment with the correct pieces and locations. Depending on your game version, the Artifact can interact with structures and affect how enemies behave around it. Treat it as a world-altering tool, not something you equip for ordinary combat.
Some of its effects are deliberately underexplained. That’s part of the charm, but it also means you should test it near a safe base rather than dropping it in the middle of a cannibal patrol. Build a small defensive perimeter first, save your game, and observe whether nearby enemies approach, retreat, or change their behavior. Multiplayer groups should coordinate before experimenting because one player’s discovery can trigger a very different reaction from the rest of the server.
The ending itself also changes based on whether you stay on the island or leave with the team. The choice affects what happens to Virginia, Kelvin, and your character, so make a manual save before the final sequence if you want to see both outcomes. It’s one of the rare survival-game decisions that gives your previous relationships real emotional weight rather than turning them into a disposable cutscene variable.
How to Hunt Secrets Without Wasting a Day
The smartest way to explore Sons of the Forest is to treat the island like a layered progression puzzle. Don’t dive into every cave the moment you see it. First collect the Rebreather, then the Rope Gun, then the Shovel. After that, clear Maintenance bunkers, gather keycards, and only then commit to the Luxury bunker and the final facilities.
| Exploration stage | Priority objective | Essential gear | Why this order works |
|---|---|---|---|
| Early game | Find the Rebreather and basic weapons | Crafted spear, axe, meds, lighter | Builds survival options before deep caves |
| Mid game | Get the Rope Gun and Shovel | Rebreather, explosives, armor | Unlocks buried hatches and advanced loot |
| Facility hunt | Clear Maintenance bunkers and keycard doors | Shotgun or crossbow, flashlight | Reveals the bunker chain and story clues |
| Late game | Claim Golden Armor and explore the Luxury bunker | VIP access, healing items, strong armor | Opens the final route and ending choices |
Use Kelvin to gather logs and Virginia as an armed companion, but don’t rely on either character to solve cave fights. Virginia can become an excellent combat partner once she has weapons, while Kelvin is better treated as a logistics assistant. Give him simple repeatable tasks and leave him at a defended camp when you’re entering a cave filled with mutants.
Finally, tune your graphics before a major expedition. Volumetric clouds, fog, ambient occlusion, and high shadow quality can cost more frames than expected, especially around bunkers and snow. If your game stutters when entering underground areas, Steamoz’s low-FPS troubleshooting guide offers practical steps for checking background processes, drivers, and frame pacing.

The island’s best secrets aren’t just collectible curiosities. They explain why the bunkers exist, connect Timmy’s story to the first game, and turn a simple rescue mission into a conspiracy buried under layers of corporate ambition. Start with the Shovel cave, keep every keycard, inspect every strange drawing, and don’t ignore the golf course. You’ll uncover the story faster—and have a much better time doing it—than someone who only follows the blinking GPS markers.
For patch notes, multiplayer changes, and current development updates, keep an eye on the official Sons of the Forest Steam news feed. The game is still capable of changing how a secret works between updates, but these locations remain the core places every curious survivor should visit.
