99 Nights in the Forest Caves: All Locations and Loot

What Caves Are in 99 Nights in the Forest?

99 Nights in the Forest hides its richest loot underground. The map contains a handful of cave systems — a small starter cave near the forest interior, deeper cave networks in the outer biomes, and the famous bat cave — and each one concentrates loot you cannot reliably get on the surface: minerals, rare crafting materials, and containers that out-yield any surface route per minute spent.

The tradeoff is that caves are the most dangerous places in the game: darkness, confined fights, swarm enemies, and no campfire safety net. This guide covers every known cave, what each contains, how to prepare, and the priority order for grabbing loot when things go wrong. For the deepest and most famous cave in the game, our dedicated bat cave guide goes even deeper.

Cave System Overview

A few system-level facts worth knowing before any descent:

• Caves are dark. Visibility inside is minimal without a torch, and fights you can't see are fights you lose.
• The campfire can't help you down there. No fire safety, no respawn convenience — an error underground costs real progress.
• Loot density is the reward. Per minute spent, a good cave run beats almost any surface route — which is exactly why the danger is worth it.
• Layouts vary between runs — based on community reports, cave entrances and layouts shift somewhat between servers, so treat directions below as patterns, not GPS coordinates.

Every Cave: Locations and What's Inside

Starter Cave

Where: near the central forest area, close enough to spawn that you'll likely find it during your first wood-gathering loops.

Entrance markers: a dark opening in rock or a hillside, usually with bare ground around it from other players' traffic on public servers.

What's inside: basic stone and mineral nodes, a few containers, and light enemy presence. This is where you take your first mining trip once you have a torch and a basic weapon. It's also the safest place to practice cave movement — confined-space fighting, torch management, and the "which way did I come from" navigation problem.

Forest Cave Network

Where: deeper in the main forest, past the areas you tour in your first days.

Entrance markers: rock faces with multiple dark openings; some entrances hide behind tree clusters.

What's inside: richer mineral nodes than the starter cave, more containers, and moderate enemy presence — wolves and bats being the usual suspects. This is your bread-and-butter mid-game cave: repeatable, profitable, close enough to camp to fit in a day's loop alongside other errands.

Biome Caves

Where: within the arctic, jungle, and volcanic biomes — each biome's cave carries its biome's hazards.

Entrance markers: openings in biome terrain — icy rock, dense overgrowth, volcanic stone.

What's inside: the best surface-adjacent materials in the game, biome-specific resources, and heavier guard presence. Environment is half the fight here: cold in the arctic cave, heat near volcanic ones. Bring biome-appropriate gear or plan short, surgical trips.

The Bat Cave

Where: deep forest; the signature cave of the game and the subject of its own guide.

Entrance markers: a distinct large opening in the deep-forest rock; veterans mark it on the map the first time they find it.

What's inside: the bat cave is the deepest, richest cave most players will ever run — dense bat swarms, valuable loot concentration, and internal passages that connect to useful map shortcuts. It's also the most dangerous content this side of the night 99 finale. The full descent — entrance, interior layout, loot priorities, and bat swarm tactics — is covered step by step in the bat cave guide.

Cave Exploration Preparation Checklist

Don't enter any cave beyond the starter cave without all five columns of this table checked:

Two behavioral rules to add:

• Enter at dawn. A cave trip should fit inside a single day with margin. Exiting at dusk into a dark forest is the classic cave death.
• Never cave alone at high difficulty. The forest network and biome caves are co-op-friendly content: one fighter covering, one player hauling. Solo trips are for the starter cave until your gear is excellent.

Cave Combat Fundamentals

Caves change the rules of fighting:

• No kiting room. Surface tactics like circling don't work when walls are two steps away. Learn to fight facing one direction, backing up in a straight line.
• Swarms are the real threat. Bats attack in numbers; a single heavy enemy is easier than a swarm you've let surround you. Never let anything get behind you — back against a wall when possible.
• Torches deter as much as they reveal. Some cave denizens keep distance from the light. Let the torch tank for you before swinging.
• Retreat is a straight line. Remember your entrance path; when things go wrong, run the line you came in on, don't improvise.

Loot Priorities: What to Grab First

When inventory fills up mid-run, this is the grab order that maximizes value per slot:

The common failure mode is the reverse: filling your bag with heavy common materials early, then having no space when the rare node appears. Grab rares first, always.

Cave loot feeds directly into your gear: minerals and rare materials upgrade through the chain covered in the weapons guide, and scrap-minded players should know caves double as a rich scavenging source — our scrap guide lists caves among the best farm stops.

Cave Shortcuts and Map Marking

Caves earn their keep twice: once for loot, once for travel. Internal passages often connect surface areas that are painfully far apart on foot, turning an all-day walk into a minutes-long transit.

• Mark every entrance you find on your map the moment you see it — both ends of any through-passage especially
• Name them by landmark, not coordinates ("cave by the frozen lake," not "cave 3")
• Test through-passage routes in daylight with a light load before trusting them as travel routes
• Treat the bat cave's connections as the backbone of late-game travel in the deep forest — veterans route their entire map around it

Common Cave Mistakes

Frequently Asked Questions

How many caves are in the game?

There's a starter cave in the central forest, a deeper forest cave network, biome caves in the arctic, jungle, and volcanic regions, and the bat cave. Based on community reports, exact entrance placement varies somewhat between servers, so explore rather than relying on fixed coordinates.

What's the best cave for beginners?

The starter cave near the central forest. Light enemy presence, basic materials, and close enough to camp that a failed trip costs you minutes, not days. Graduate to the forest network once you can handle confined fights comfortably.

What should I bring into a cave?

At minimum: 2–3 torches, your best weapon, armor, food or first aid, and fuel for the return trip. The full checklist with the reasons behind each item is in the preparation section above.

Are caves worth the risk?

Yes — per minute spent, caves are the highest-yield loot activity in the game, and their through-passages double as travel shortcuts once mapped. The risk is front-loaded: prepare properly and the danger drops faster than the loot does.

Do cave entrances change between servers?

Based on community reports, entrance locations and some layouts shift between runs. The cave types and their general regions are consistent; the exact positions are not. Mark what you find on your own map.
