Genshin Impact’s expansive worldbuilding takes another leap in Natlan, introducing players to fiery new mechanics, tribal cultures, and the long-anticipated Pyro Archon. Among Natlan’s standout zones are the Basin of Unnumbered Flames and Coatepec Mountain—two regions rich with lore, elemental puzzles, and of course, hidden chests waiting to be discovered.

These hidden chests are perfect for stocking up on Primogems, Ascension materials, and Artisan artifacts, especially for those aiming to reach 100% exploration. If you’re venturing through these volcanic lands, here’s a complete breakdown of all 7 hidden chest locations across both regions, plus pro tips to make your exploration smoother.

🔥 Hidden Chests in the Basin of Unnumbered Flames

🌋 Chest #1 – Warrior Ambush Near the Cliff

• Teleport to: Eastern waypoint in the Basin

• Look: Immediately to your right—some tribal warriors are standing near a large rock

• Mechanic: Defeat all the enemies to unlock a Common Chest

This encounter is easy to overlook due to the rock blending into the terrain. Use area-of-effect attacks to quickly dispatch grouped enemies.

🔥 Chest #2 – The Lonely Campfire

• Teleport to: The rightmost waypoint in the Basin

• Glide: Left toward a lone hilichurl beside an unlit campfire

• Mechanic: Use a Pyro character (Amber, Bennett, etc.) to ignite the fire and reveal a Chest

The chest is time-locked to the fire’s activation, so light it as soon as you land.

🍎 Chest #3 – Among the Alpacas

• Teleport to: Statue of the Seven in the Basin

• Head: Toward the alpaca herd on your left

• Mechanic: Pick all the Sunsettias in the area to make the chest spawn

This reward favors careful exploration. If even one fruit is missed, the chest won’t appear—so double-check!

🥚 Chest #4 – Eggs and Ambush

• Near: Chest #3, walk to a nearby campsite hidden behind bushes

• Mechanic: Collect all visible eggs in the camp

• Trigger: An ambush of tribal enemies will appear—defeat them to earn a Chest

AoE and crowd control are helpful here, as multiple melee enemies may attack at once.

🐞 Chest #5 – Crystal Beetle and Apple Bait

• Teleport to: Waypoint near the Scions of the Canopy tribe

• Head: Left toward a rocky ledge with apples on the ground

• Mechanic:

  1. Pick up all the apples

  2. Jump down to grab two Crystal Beetles

  3. Interact with the glowing spot to spawn a Chest

This is a multi-step sequence that many players miss. Make sure to collect in the right order!

💎 Chest #6 – Crystal Ambush at the Summit

• Teleport to: Scions of the Canopy Statue of the Seven

• Climb: The mountain left of the statue (use Kachina, Xilonen, or Saurian Form for easier mobility)

• Mechanic: Find a glowing stone surrounded by crystal ore. Break it to summon a Lava Avatar

• Reward: Defeat it to earn a Chest

This elite-type enemy deals heavy Pyro damage—bring shielders or Hydro characters to mitigate the threat.

🧨 Chest #7 – Slime Pit at Ancestral Temple

• Teleport to: Central waypoint at the Ancestral Temple

• Jump: Down toward the visible slimes next to crystal ore

• Mechanic: Defeat the slimes, triggering a Lava Avatar to spawn

• Reward: Once defeated, you’ll receive a Precious Chest

This chest has one of the better rewards among the seven and is perfect for mid-to-late-game players hunting for higher-tier artifacts.

💡 Pro Tips for Exploring Natlan’s Hidden Treasures

• Unlock all nearby waypoints before chest hunting. The terrain in Natlan, especially around Coatepec Mountain, is vertical and travel-heavy.

• Keep a Pyro character in your party—many chests are tied to environmental triggers.

• Always explore in Saurian form when possible. This mechanic often unveils underground clues or glowing points that lead to puzzles.

• Use characters like Xilonen or Mavuika who can navigate mountainous regions with ease.
