If you're like most players of 99 Nights in the Forest, you know that loot can make or break your survival. While the game already offers plenty of resources through quests and battles, some of the best rewards are stashed away in hidden corners of the map. Over dozens of playthroughs, I’ve stumbled upon several lesser-known areas that are absolutely worth your time — especially if you’re aiming to farm rare materials or make better use of your 99 Nights in the Forest diamonds.

Here are 9 hidden locations I recommend exploring:

1. Mosswood Cavern (Northwest Ridge)

Hidden behind a waterfall, Mosswood Cavern is easy to overlook. Inside, you’ll find a chest that often contains rare crafting components. Bring torches — it’s pitch dark. Great place to stock up before using your 99 Nights in the Forest diamonds for gear upgrades.

2. The Hollow Tree (Southwest Swamp)

This giant, hollowed-out tree is barely visible from the path, but step inside and you'll discover a mini-dungeon with three loot stashes. It's especially good for gathering potion ingredients.

3. Forgotten Miner's Camp (Cliffside East)

Past the broken bridge lies an abandoned camp. Not only are there forgotten supply crates, but mining the surrounding area yields rare ores perfect for high-tier crafting. If you’ve already chosen to buy 99 Nights in the Forest diamonds, consider combining those with what you loot here to maximize upgrades.

4. Shrouded Shrine (Deep Forest)

This ancient shrine isn't marked on the map. Defeat the forest guardians here, and you’ll gain access to a treasure vault that sometimes contains diamond fragments — a real bonus if you're short on 99 Nights in the Forest diamonds.

5. Sunken Tunnel (Under the Lake)

Near the western lake is a diving spot that leads to a submerged tunnel. It’s tricky without stamina potions, but if you reach the end, there’s a chest filled with rare relics. These can be sold or combined with gear to enhance your build.

6. Crumbled Tower (North Forest Edge)

Only the foundation remains, but dig around this area and you’ll find buried supplies. You’ll also occasionally trigger a random event that spawns elite mobs with high loot drop rates.

7. Whispering Glade (Behind Spirit Rock)

You’ll hear strange whispers when you’re close. This glade has mushrooms that boost stamina regeneration and a hidden chest nestled between two boulders. This is a good early-game spot to prep before spending any 99 Nights in the Forest diamonds on consumables.

8. Old Hermit's Hideout (East Hillside)

Tucked away behind thick vines, this hut holds journals, tools, and even a rare weapon or two. It’s especially helpful for players focused on solo builds. Combine the finds here with U4GM-recommended builds for even better synergy.

9. Cursed Dock (Far Southeast Marshes)

Only visible at night, this rickety dock spawns a ghost ship every third in-game night. If you defeat the mini-boss onboard, the loot includes event tokens, upgrade scrolls, and sometimes bonus diamonds — making it one of the best hidden spots for serious hunters.

Exploring these lesser-known areas adds depth and reward to your gameplay, especially if you're optimizing your time and inventory. Whether you're playing as a solo survivor or a co-op strategist, mixing loot hunting with smart diamond spending is key. If you're looking to speed up progress, some players choose to buy 99 Nights in the Forest diamonds from sources like U4GM, but even if you’re F2P, these locations will keep your stash full and your gear competitive.
