Exploring the vast Hydro region of Fontaine in Genshin Impact reveals countless hidden treasures, but none offer greater rewards than the mysterious Shrines of Depths. Finding and opening these ancient structures grants players rare Primogems, high-tier artifacts, and valuable upgrade materials. Achieving complete access to these locations requires a strategic mix of regional exploration, offering items to landmarks, and solving unique underwater puzzles.

Securing the Specialized Hydro Keys

Before you can open any of the sealed structures, you must obtain the corresponding Fontaine Shrine of Depths keys. These specialized items are earned primarily by leveling up the Statue of the Seven using collected Hydroculi scattered across the land. Additionally, offering Hydro Sigils to the Fountain of Lucine rewards dedicated travelers with extra keys at specific milestone levels.

It is highly recommended to gather several keys before plotting your travel route to minimize backtracking across the multi-layered map. Keeping track of your exploration progress ensures you always have a key ready when stumbling upon a hidden vault.

Navigating the Surface Shrines

Several shrines are situated on the grassy surface plains and steep cliffs of the Court of Fontaine and Belleau regions. One can be easily spotted standing on a high ridge north of the main city, offering a clear view of the surrounding aquatic landscape. Another surface structure rests quietly near the southern hills of the Beryl region, surrounded by local wildlife and enemy camps.

Reaching these landmarks typically involves using nearby Teleport Waypoints and gliding down from elevated peaks. Players should prepare their stamina-restoring food items to ensure smooth traversal across these towering vertical environments.

Diving Into the Submerged Vaults

Fontaine introduces a groundbreaking underwater exploration mechanic, and multiple shrines are completely submerged within deep aquatic trenches. You will need to dive into the Elton Trench and the Thalatta Submarine Canyon to locate these glowing blue structures resting on the seabed. Navigating the depths requires utilizing the unique aquatic currents to move through the water at high speed.

Opening these deep-sea vaults requires players to master basic underwater combat and puzzle-solving mechanics to clear surrounding hazards. Taking the time to explore the sea floor thoroughly will reveal the exact pathways leading directly to these high-tier chests.

Maximizing Your Exploration Rewards

Each unlocked shrine contains a single Luxurious Chest packed with essential progression resources that significantly boost your account strength. Beyond the guaranteed Primogems, players will receive Adventure EXP, local sigils, and random high-rarity artifacts. These materials are crucial for leveling up your characters and preparing for tougher late-game challenges.

Combining your shrine hunt with active world quests allows you to clear multiple regional objectives simultaneously. Tracking every location systematically ensures that no valuable resource is left behind in the Hydro nation.
