Fontaine is the region of law and justice, where the people worship Focalors, the Hydro Archon in Genshin Impact. As Fontaine is associated with Hydro, the nation is surrounded by water as it should be, and Travelers can even explore underwater areas after completing certain tasks.
Aside from uncovering hidden treasure chests around the region, players can also collect Hydroculus to be offered to the Statue of the Seven in Fontaine. In the Belleau Region, there are 17 Hydroculus to be collected, both aboveground and underwater. Most of the Hydroculus in this guide are not locked behind any quests, so even new players won't have any difficulty collecting them.
Genshin Impact: Vissudha Field Dendroculus Locations
Collect all the Dendroculus in Vissudha Field for the Statue of the Seven in Genshin Impact's Sumeru region.
Belleau Region Hydroculus Location 1
Start with the Statue of the Seven in Romaritime Harbor and head southwest. Glide downwards toward a ship, and you can get a Hydroculus on top of the ship.
Belleau Region Hydroculus Location 2
Return to the Statue of the Seven and walk forward to the Hydroculus right in front. If there is no Aquabus in sight, approach the chair on the side and choose the option to 'wait for the aquabus'. Once it arrives, you can step on the aquabus to reach the Hydroculus.

Teleport to the Denouement of Sin Domain and climb the mountain to get to the Hydroculus at the top.
Belleau Region Hydroculus Location 4
Go to the underwater waypoint southwest of the West Slopes of Mont Automnequi (the waypoint that leads to the Emperor of Fire and Iron boss). Once you arrive, enter the water in the northwest to get to the Hydroculus.
Belleau Region Hydroculus Location 5
After you're done with the underwater area, use the ground-level waypoint southwest of the West Slopes of Mont Automnequi. Walk southeast to the small island to find a Hydroculus beside a Hilichurl Rogue.
Belleau Region Hydroculus Location 6
From the previous spot, head southwest to a ship. There will be another Hydroculus on top of the ship.

Return to the waypoint southwest of the West Slopes of Mont Automnequi and climb the mountain to the north so you can reach the Oculus at the top.
Belleau Region Hydroculus Location 8
From the previous position on top of the mountain, glide east towards the roof of a small house. On top of the house, there will be a small teleportation bubble you can use to reach the floating Hydroculus in the air.
Belleau Region Hydroculus Location 9
Now, teleport to the waypoint north of the West Slopes of Mont Automnequi. Jump down to the front and enter the aquabus tunnel to find a Hydroculus on top of the water. Use a tall character to jump over and glide towards the Oculus.
Belleau Region Hydroculus Location 10
Return to the previous waypoint and climb the mountain on the southeast. Once at the top of the mountain, use an Anemo skill on the windmill mechanism to create a wind current. Open your glider to float and get the Hydroculus at the top.
Belleau Region Hydroculus Location 11
Use the underground waypoint in Poisson and head further inside the cave to the pool. Enter the pool of water to find a Hydroculus.
Belleau Region Hydroculus Location 12
From the previous spot, climb back up to the ground and head further inside the Poisson cave to the huge ship. Climb to the top of the ship to get the Hydroculus.
Belleau Region Hydroculus Location 13
Teleport to the underground waypoint in Poisson again and turn around to use the bubble teleportation to reach the above ground. Up there, climb the ship to the top to reach the Hydroculus. There are many holes in the shipwreck, so proceed with caution, or you might fall off the ship and need to try again from the start.
Belleau Region Hydroculus Location 14
From the previous spot, glide northeast to the tall building with the Pneumousia Relay puzzle on the ground. Complete the puzzle so that a teleportation bubble will appear, and you can use it to reach the Hydroculus on top of the building.
Belleau Region Hydroculus Location 15
From the previous spot at the top of the building, glide to the northwest to another Oculus on the rooftop of a small house near the shore.
Belleau Region Hydroculus Location 16
Head southwest and get in the water, then swim in the same direction to find the Hydroculus beside the coral.
Belleau Region Hydroculus Location 17
The last Hydroculus in the Belleau Region is in an underwater ruin south of the East Slopes of Mont Automnequi. You can reach this area by teleporting to the Waterfall Wen Domain and heading east to the Waverider Waypoint. Then, dive into the water before swimming to the west to enter the cave. The puzzle in this underwater cavern belongs to the Search In The Algae Sea Quest, so it's best if you do it along so you can reach the Hydroculus much easily.
