Look, let’s be real for a second. If you’ve spent more than five hours on The Island in ARK: Survival Evolved, you’ve probably stared at a dark hole in a rock wall and thought, "Yeah, absolutely not." I get it. The caves on the island ark are basically designed to ruin your day, your gear, and your favorite tames. They aren't just holes in the ground; they’re high-stakes gear checks that Wildcard Studios threw in to make sure you’re actually paying attention. You go in looking for an Artifact to summon a boss, and you come out—if you come out—with broken armor and a newfound hatred for Mega Rabies.
It’s easy to think you’re ready. You’ve got a high-level Rex and some flak armor. You feel like a god. Then you step into the Lower South Cave and realize your Rex is too fat to fit through the door. Suddenly, you’re on foot, it’s pitch black, and there’s a level 150 Araneo crawling on your ceiling. This is the reality of the Island’s underground. It’s cramped. It’s vertical. It’s honestly a bit of a nightmare if you don't have a plan.
The Brutal Reality of the Lower South Cave
Most people start here. It’s the "easy" cave. But honestly? Easy is a lie. Located near the southern coast (lat 80.2, lon 53.5), the Lower South Cave is the first time the game really tries to kill you with environmental pressure. You’re looking for the Artifact of the Hunter.
The heat is the first thing that hits you. If you aren't wearing ghillie or at least carrying a few canteens, you’re going to dehydrate before you even see a Titanoboa. This cave is the ultimate test of your "foot game." Since you can't bring big tames in, you’re usually relying on a Baryonyx or a high-level Raptor. The Baryonyx is the undisputed king here because of that tail spin in the water sections.

One thing people always get wrong is the pathing. You’ll see a fork in the road and think it doesn't matter. It matters. Go left, and you’re circling back to the entrance like a loser. Go right, and you’re dropping into a pit of scorpions. It’s claustrophobic. The walls feel like they’re closing in, and the sound of chittering insects is constant. If you get bit by a Megalania hanging from the ceiling, you’re getting Mega Rabies. Your health will tick down, and you’ll panic. Bring Lesser Antidote. Seriously. Just bring it.
The Snow Cave is Actually a Death Trap
We need to talk about the Caverns of Lost Faith and Lost Hope later, but first, let’s address the elephant in the room: the Snow Cave (the North West Cave or "Strong" Cave). This place is tucked away in the frozen tundra at 29.1, 31.8.
It is miserable.
You aren't just fighting dinos here; you’re fighting the literal temperature. Even with 1,000 armor points and high fortitude, the "Extreme Cold" debuff will eat your HP. You need high-quality Fur Armor, and even then, you probably need a Fria Curry active. Inside, you’ll find Yetis and Polar Bears. These aren't your average Island variants. They have massive health pools and hit like freight trains.
The most annoying part? The "Purlovia mines." These jerks bury themselves in the snow and wait for you to walk by. They stun you, knock you off your mount, and then the Yetis finish the job. You can’t just run through this. You have to use a Yutyrannus or a high-level Direwolf to sniff them out. Or, if you’re feeling spicy, use grenades to flush them. Most players fail here because they underestimate the knockback. One bad hit and you’re falling into a freezing pond, which is a death sentence.

Why the Swamp Cave is the Best (and Worst) Place for XP
If you want to level up fast, you go to the Swamp Cave (62.7, 37.3). This is where the Artifact of the Immune lives. But here’s the catch: the air is literally poison.
If you walk in without a Gas Mask or a full set of Scuba gear, you die in seconds. Not minutes. Seconds. The density of mobs in here is insane. We’re talking hundreds of Meganeura, Titanoboa, and Leeches. It’s a literal wall of meat.
- The Gas Mask Strategy: It’s expensive but worth it. Just watch the durability.
- The Megatherium Trick: This is the pro move. If you can cryopod a Megatherium inside, you win. The "Bug Killer" buff makes it nearly invincible against the insect swarms.
- The Loot: This cave has some of the best red loot crates on the map. It’s why people risk it.
The Swamp Cave is a perfect example of ARK’s "high risk, high reward" philosophy. It feels like a dungeon from an old-school MMO. You have to manage your resources, keep an eye on your mask durability, and make sure your tame doesn't get overwhelmed by leeches. If you forget your bug repellant, you’re going to have a bad time.
The Underwater Caves: A Different Kind of Stress
There are two major underwater caves on the island ark, and they are genuinely terrifying. The Cavern of Lost Faith (West) and the Cavern of Lost Hope (East).
The East cave is significantly harder. It’s packed with Alpha Mosasauruses, Cnidaria (the bane of my existence), and Electrophorus. If you get shocked, you’re paralyzed. Then the sharks come. It’s a chaotic mess of blue light and biting teeth.
Most people try to use a Basilosaurus because it’s immune to shocks. That’s smart. But the Basilo takes damage when it goes too deep. It’s a constant balancing act. You’re deep underwater, your oxygen is ticking down, and you can’t see more than twenty feet in front of you because of the murk. It’s the peak of ARK’s atmospheric horror. You realize very quickly that you are not the apex predator in the ocean.
The Hidden Details of the Tek Cave
Once you’ve gathered all the artifacts from the other caves, you head to the volcano. The Tek Cave. This isn't just another cave; it’s the final gauntlet.
The heat is unbearable at the start, then it gets freezing. You need to swap gear mid-run. You’re leading a train of 20+ dinos down a narrow path over rivers of lava. If your Rex falls in, it’s gone. Deleted. No recovery. The pathing AI is... let’s call it "challenging." You’ll spend half the time whistling "follow" and the other half screaming because your Yuty decided to take a bath in the magma.
This cave is the ultimate test of everything you’ve learned. It requires precise movement, temperature management, and raw firepower. It’s not about exploring; it’s about survival.
Actionable Strategy for Your Next Run
Stop treating caves like open-world combat. They are tactical encounters. If you want to actually survive the caves on the island ark, follow these rules:
✨ Don't miss: How the Path of the Chosen in AC Shadows Actually Changes the Way You Play
- Cryopods are Non-Negotiable: Don’t try to squeeze a mount through a tiny crack. Bring it in a pod, clear a room, and deploy it where there’s space.
- The Medical Brew Stack: You should never have fewer than 50 Medical Brews on your hotbar. Passive healing is the only way to survive the chip damage from bats and bugs.
- Grappling Hooks: These are your "get out of jail free" card. If you fall into a pit or need to escape a swarm, hook the ceiling and get out of there.
- Baryonyx Supremacy: For 90% of the land caves, a high-level, bred Baryonyx is better than a Rex. It heals instantly from eating fish, it fits in tight spaces, and it can swim.
- Otters are Secretly OP: An Otter on your shoulder provides insulation. It helps with the freezing cold of the Snow Cave and the blistering heat of the lava zones. Plus, they can carry multiple Artifacts.
Success in these caves isn't about being the strongest; it’s about being the most prepared. Check your armor durability before you go in. Bring extra water. And for the love of everything, don't forget the Lesser Antidote. You’ll thank me when the first Megalania bites you.
Go back to your base and start breeding a high-stat Baryonyx. Look for one with at least 3,000 health and 400% melee before you even think about the harder chambers. Once you have that, start crafting your Gas Masks. The Swamp Cave is waiting, and those Red Crates aren't going to loot themselves. Get moving.
