Reach Crystal-Tree Grotto in Genshin Impact by following Let Not All Rivers Run Dry through Teplo Oasis. The mission follows Glinin’s survey of Novokitezhgrad’s water, with Thrud accompanying the journey underground. Its route also leads into Waterway to the Falls, a connected area reached near the end of the quest. Complete the prerequisite missions first, then follow the entrance and waterway steps below to explore both areas.

Check your quest list for Let Not All Rivers Run Dry before heading toward the grotto. Finding the entrance alone does not open the passage inside.

Start with the city quest
How to enter Crystal-Tree Grotto
Drop into the hole at Teplo Oasis
Follow Let Not All Rivers Run Dry until the group visits Teplo Oasis. The entrance sequence happens after you encounter growing Blightkristalls there.
- Continue the quest through the Teplo Oasis visit.
- Escape from the growing Blightkristalls with the group.
- Jump into the hole along the quest route to enter Crystal-Tree Grotto.
Use that encounter as your route marker. The grotto is below the oasis, so the quest takes you down through an opening instead of through a surface doorway.

Drop below Teplo Oasis
Open the blocked passage
You can jump into the entrance hole before doing the quest, but a Blightkristall blocks the way farther inside. An early visit stops at that obstruction.
If you have already reached the hole without advancing the mission, return to the quest objectives. The construct unlock is part of the required route into the grotto.
How to reach Waterway to the Falls
Follow the water onward
Continue Let Not All Rivers Run Dry until the objective directs you to follow the water’s flow onward. This step occurs near the end of the mission and leads into Waterway to the Falls.
The waterway is part of the Crystal-Tree Grotto area. Its exit returns the group to Downtown Novokitezhgrad, completing the route back to the city.
If you are visiting Waterway to the Falls for Kristallfold, complete Let Not All Rivers Run Dry before starting that gathering trip. Follow the mission through its final stretch instead of stopping once you enter the grotto.
What to check before leaving the grotto
Complete the two exploration puzzles
Crystal-Tree Grotto contains two puzzle activities to check during exploration:
- The Blightkristall puzzle.
- The Dimmed Plant puzzle.
Completing the pair awards two Precious Chests in total. Check both puzzle sites before taking the waterway exit back to Novokitezhgrad.
