The volcanic land of Atocpan in Genshin Impact’s Natlan region is filled with secrets, puzzles, and valuable loot—if you know where to look. With the release of version 5.0, Atocpan and the surrounding Ancient Sacred Mountain introduced not only new mechanics like Indwelling Saurians and Phlogiston rocks, but also a generous helping of hidden chests tucked away through environmental challenges, puzzles, and character interactions.

This guide outlines the best hidden chests in Atocpan, including how to find them, complete their triggers, and maximize your exploration rewards.

🧭 Why You Should Hunt Hidden Chests in Atocpan

Hidden chests in Natlan are more than just loot—they often unlock Achievements, advance local exploration, and contain valuable rewards like:

• Primogems

• Mora

• Artifacts

• Materials

• Radiant Spincrystals for teapot music

Thoroughly clearing Atocpan will also raise your Exploration Progress, helping you achieve region completion goals for additional bonuses.
