How To Get To Crystal-Tree Grotto & Waterway to the Falls In Genshin Impact

Putting it simply, if you want to go to the Crystal-Tree Grotto and Waterway to the Falls in Genshin Impact, you need to trigger and complete the Let Not All Rivers Run Dry quest. This mission takes players on a journey with Thrud and Glinin, where Glinin wishes to survey the water of Novokitezhgrad, only to find something bigger hidden by the flowing water. After all, it's normal for people to take things for granted and not think about where their water and air came from.
