You're standing at the mouth of a dark, damp hole in the side of a mountain. Your torch is flickering. You hear something—a skittering sound—deep inside. If you’re playing ARK: Survival Evolved or the Ascended remake, you know exactly what’s coming. ARK caves the island explorers deal with are some of the most claustrophobic, frustrating, and rewarding parts of the entire game. Honestly? They’re terrifying. But if you want those artifacts to summon the bosses, you have no choice. You have to go in.
Most players treat caves like a regular combat encounter. That’s a mistake. A big one. These aren't just holes in the ground; they are specialized ecosystems designed to punish gear failure.
The Brutal Reality of The Island’s Underground
There are roughly ten major caves on The Island, not counting the underwater ones that are basically suicide missions without a high-level Basilosaurus. Each one serves a specific purpose, usually guarding an Artifact. You need these Artifacts to open the Tek Cave and eventually face the Overseer. But let’s be real: most people visit ARK caves the island offers because of the loot drops. The red crates in the Swamp Cave? Those are legendary for a reason.
Temperatures inside these caves fluctuate wildly. You might be freezing in the Snow Cave one minute and then melting in the Lava Cave the next. It’s not just about the dinos. It's about the environment trying to kill you before you even see a Mega Desmodus or a group of Onycs.
Lower South Cave: Your First Real Test
Located near the southern coast (roughly 80.2, 53.5), the Lower South Cave is usually the first one survivors tackle. It’s the "baby's first cave," but don't let that fool you. If you go in naked with a stone hatchet, you’re done.

It’s humid. It’s cramped. You’ll find the Artifact of the Hunter here. The main threats are Dilophosaurs, Titanoboa, and those annoying Pulmonoscorpius that will knock you out before you can say "stimberry." Seriously, bring Stimulants. If your torpor hits the limit, you're just a buffet for snakes. A high-level Baryonyx is the gold standard here because it fits through the gaps and can heal quickly by eating the fish in the small pools.
The Central Cave: A Chokepoint of Chaos
Found near the Volcano (41.5, 46.9), the Central Cave holds the Artifact of the Clever. It’s vertical. Very vertical. If you don't have a grappling hook, you’re going to spend three hours trying to parkour over rocks while Sarcos try to pull you into the water.
The density of Araneo (spiders) here is staggering. They slow you down with webs. Then the scorpions move in. It’s a mess. Most veterans use a Sabertooth or a Thylacoleo here. The Thyla is particularly great because it can climb the walls, giving you a literal leg up on the swarms.
Why the Swamp Cave is Actually the Hardest
Forget the bosses for a second. The Swamp Cave (62.7, 37.3) is arguably the most dangerous spot on the map. Why? The air is toxic. If you walk in without a Gas Mask or a full set of SCUBA gear, you will lose health every second until you’re a corpse.

It’s packed with Meganeura. Hundreds of them. When you kill one thing, the entire room’s worth of dragonflies swarms you. It’s a lag-inducing nightmare. But the loot? The loot is incredible. People farm this cave for high-tier riot gear and Rex saddles. If you have a high-level Megatherium, use it. The "Bug Buff" makes the Megatherium an absolute god in this specific ARK caves the island location. It gets a massive damage and resistance boost every time it kills an insect. You’ll be tearing through level 300 spiders like they’re made of paper.
The Cold Hard Truth About the Snow Cave
The Caverns of Lost Faith and Lost Hope are underwater, but the "Snow Cave" (29.1, 31.8) is a different beast entirely. It’s freezing. Even with high-tier Fur Gear, you might still take cold damage.
Inside, you’ll find Direwolves and Anglerfish in the water transitions, but the real threat is the Purlovia. These things bury themselves in the ground and jump out to dismount you. Once you’re off your dino, you’re usually dead. The levels here also break the standard rules; you’ll see creatures well over the level 150 cap. It’s brutal. It’s unfair. It’s ARK.
Preparing Your Kit: The Non-Negotiables
Don't be the person who flies to a cave on a Pteranodon and expects to wing it. You need a checklist.

- Medical Brews: Bring at least 50. You will take chip damage from bats (Onyc) that carry Mega Rabies.
- Grappling Hooks: These aren't optional. They save you from falling into lava or getting stuck in a pit.
- Fria Curry and Calien Soup: Manage your temperature.
- Otters: An Otter on your shoulder provides insulation and can carry multiple Artifacts. This is a pro-tip that many miss.
- Extra Armor: Arthropluera (the giant centipedes) spit acid that breaks your armor instantly. Carry a spare set of Flak.
Dealing with Mega Rabies
If a bat bites you and you see a green cloud around your head, you have Mega Rabies. Your health and stamina will drain rapidly. It’s contagious. If you’re playing with friends, stay away from them or you’ll infect the whole squad. Lesser Antidotes are the cure, but they expire quickly in your inventory. Keeping a few in a Preserving Bin near the cave entrance is a smart move.
The Underwater Caves: A Different Game Entirely
The Cavern of Lost Hope (45.9, 88.9) is a nightmare of Alpha Mosasaurs and Cnidaria (jellyfish). If a jellyfish touches you, you're stunned. Your mount is stunned. You both die.
You need a Basilosaurus. Why? They are immune to the shock attacks of jellyfish and the grab of the Tusoteuthis (squid). They aren't the fastest, but they are the only reliable way to navigate the deep-sea ARK caves the island hides beneath the waves. The loot crates here are the only way to get some of the most advanced Tek blueprints, so eventually, you'll have to take the plunge.
Essential Actionable Steps for Cave Diving
To survive and actually thrive in these environments, stop rushing. ARK rewards the patient and punishes the arrogant.
- Tame a high-level Baryonyx. It is the most versatile cave mount in the game. It jumps, it swims, it spins, and it fits through almost every door.
- Breed your cave mounts. Don't take your original "parent" tames into a cave. Take the babies. You will lose dinos to lava or glitchy physics. It's better to lose a clone than your primary breeder.
- Build "Fobs" (Forward Operating Bases). Put a small 1x1 stone hut with a bed and a storage box near the cave entrance. If you die, you can respawn right there and try to recover your gear before it despawns.
- Use Cryopods. In the Ascended version, cryopod rules have changed, but if you're on a server that allows them, use them to get large dinos past narrow "squeeze" points in the rock.
- Check your light. Some caves are pitch black. A Gamma setting tweak helps, but a high-quality torch or a mining helmet keeps your hands free for weapons.
The caves on The Island are designed as progressive hurdles. You start in the south, gather your strength, and eventually head into the frozen north or the deep blue. Every cave teaches you something—usually through a painful death. Master the gear, respect the levels, and always, always bring more Stimulants than you think you need.
