All 85 Hydroculus Locations in Genshin Impact

The Fontaine region of Genshin Impact, which made its debut in Version 4.0, is associated with the Hydro element. Keeping with tradition, the main collectible of Fontaine is the Hydroculus, which is a Hydro-themed version of the orbs that Genshin Impact players have been collecting since the game’s initial release all the way back in 2020.

While Fontaine might seem like a smaller region than Sumeru or Inazuma, its size is deceiving since it is home to multiple underground sections and freely explorable bodies of water. There are 85 Hydroculi hidden across Fontaine, and if you’re looking to collect them all to upgrade the region’s Statues of the Seven, this guide will walk you through where to find them all.

All Hydroculus Locations in Genshin Impact

As always, you can find Hydroculi floating throughout Fontaine. Some of them are laying in plain sight, while others require puzzles to be solved in order to claim them. Since Fontaine has such a huge focus on swimming, remember that most will be underwater. Plus, some may be hidden underground.

Court of Fontaine Hydroculus Locations

There are 40 Hydroculi located in the Court of Fontaine region of Fontaine. It’s the northernmost part of the Fontaine, comprised of Marcotte Station, the Fountain of Lucine, the Opera Epiclese, and the Court of Fontaine itself in addition to the underwater areas surrounding it.

Hydroculus #1

The first Hydroculus can be found at the end of the Aquabus rail line leading north out of the Court of Fontaine.

Hydroculus #2

This Hydroculus is located on top of a Hillichurl camp building.

Hydroculus #3

For the third Hydroculus, you’ll need to bring an Anemo character to glide into the sky since the Hydroculus is floating in the air.

Hydroculus #4

This Hydroculus is sitting on top of a silo next to a small building just a short distance away from the previous Hydroculus.

Hydroculus #5

This Hydroculus is perched atop a tall tower. You’ll need to climb the nearby mountain and glide to it in order to reach it.

Hydroculus #6

This Hydroculus is located underwater in the Annapausis area. This region is part of the world quest “The Narzissenkreuz Adventure.” At the main structure, hit one of the crystals to summon a watery platform and then use the water ring to propel yourself northeast toward this Hydroculus.

Hydroculus #7

This Hydroculus is also located underground in the Annapausis region. It’s floating in the air in the southwestern corner of the area, so you’ll have to climb up high and glide to it to claim it.

Hydroculus #8

To get this Hydroculus, teleport to the waypoint in the underwater Annapausis area. The Hydroculus is sitting on a ledge just to the east of it.

Hydroculus #9

This Hydroculus is floating way up high in the sky, so you’ll need to solve a short puzzle to reach it. There are three Seelies surrounding the nearby chest on a small island underneath it. Bring them to their pedestals and a wind current will appear that launches you up to this Hydroculus.

Hydroculus #10

The tenth Hydroculus is perched atop a high mountaintop. You can climb the mountain or glide to it from the Court of Fontaine walls.

Hydroculus #11

This Hydroculus involves a lengthy climb to the highest point of the Court of Fontaine. It’s really easy to spot, but getting up there takes some time. Thankfully, the tower has some spots for you to rest and regain stamina along the way.

Hydroculus #12

The next Hydroculus is sitting on a large bowl-shaped roof along the northeastern wall of the Court of Fontaine.

Hydroculus #13

The thirteenth Hydroculus is floating in the middle of a shallow lake just outside the eastern wall of the Court of Fontaine.
