Fontaine Shrine Treasure Hunt Guide for Completionists

Tracking down every single Fontaine Shrine of Depths is a core milestone for any dedicated completionist exploring the Hydro region in Genshin Impact. Unlike previous nations where monuments remained strictly on land, Fontaine introduces a unique mix of terrestrial landmarks and deep underwater structures. Successfully unlocking all these hidden vaults requires a strategic combination of regional exploration, offering systems, and map tracking.
Securing the Hydro Keys Through Progression
Before you can begin breaking the ancient seals, you must gather the specialized keys required to access the luxurious chests. These rare items are primarily obtained by offering collected Hydroculus orbs to upgrade the regional Statues of the Seven. Additionally, players can secure keys by offering gathered Hydro Sigils to maximize the levels of the Fountain of Lucine.
Because keys do not correspond to specific shrines, you can use any unlocked key on any monument across the territory. Completionists should focus on gathering these resources early to avoid unnecessary backtracking during their treasure hunt sessions. Keeping a steady eye on your offering milestones ensures you always have a key ready when a new blue glow is spotted.
Navigating the Surface Level Shrines
The surface structures are scattered across diverse northern and southern sub-regions, often resting atop steep cliffs or hidden within orchards. For instance, one notable shrine can be found nestled quietly behind an orchard just north of the Court of Fontaine city walls. Another terrestrial monument stands near the western hills of Elynas, requiring a short climb from the nearby Statue of the Seven.
To optimize your travel route, always utilize high-altitude Teleport Waypoints to glide down toward your targets smoothly. Tracking the monuments north of Marcotte Station or along the cliffs of Erinnyes Forest requires minimal effort if you map your vertical paths beforehand. These overland locations provide excellent vantage points to plan your next destination across the beautiful landscape.
Exploring the Deep Underwater Zones
Fontaine sets itself apart by submerging several of its ancient structures deep within complex aquatic trenches. Dedicated players must dive into the depths of the Elton Trench to locate a shrine hidden among massive green aquatic plants. Navigating these multi-layered marine environments demands a firm understanding of the local underwater mechanics and diving systems.
Another submerged vault rests southwest of the Central Laboratory Ruins, easily accessible by diving directly into the waters below the region. The Sea of Bygone Eras also holds hidden challenges, requiring players to swim through ancient ruins to claim their rewards. Mastering these aquatic routes is essential for achieving the maximum exploration percentage in the Nation of Justice.
Maximizing Your Completionist Achievements
Unlocking every available monument provides a substantial boost of four percent to your overall area exploration progress. Each luxurious chest inside contains valuable Primogems, local sigils, and high-tier artifacts to enhance your character roster. Successfully opening all ten hidden chambers awards players a unique achievement that cements their legendary status as Teyvat explorers.
