You can find this Domain on your map in The Chasm near the Fuao Vale. I recommend you teleport to the Geo Statue of The Seven closest to it to find your way there fast. Walking up to the supposed entrance shows that a rock with the Geo symbol is blocking it. An Ancient Stone Tablet sits in front of it.

Nearby, is a stone Pressure Plate. Before you can go into puzzle mode, you’ll want to get rid of the enemies that spawn in with a chest. After defeating them and claiming your reward, you can focus on the puzzle. The Pressure Plate will activate using Geo abilities, specifically ones that create Geo Constructs. If you don’t have someone like Ningguang or Zhongli, you should use the Traveler’s Geo abilities.

Lost Valley Domain puzzle instructions

First, place a Geo Construct on top of the Pressure Plate. Then, walk behind you, and you should spot some very large rocks containing Geo resonance. You’ll know if they’re the ones if they have three Anemo Rings between them that you can fly through. Now get on top of the farthest one with the strange swirls of yellow mist. Activate another Geo ability or construct on top of this rock. This will cause a wave of Geo energy to push out toward the Domain entrance.

Personally, I used Ningguang’s Geo Construct to keep the Pressure Plate activated, and used Noelle’s Elemental Skill to activate the Geo energy wave. If you only have the Traveler, you can use their Geo Construct ability both on the Pressure Plate and the large Geo rock. With the Pressure Plate still activated, and the Geo wave of energy hitting the entrance, it should trigger a cutscene, and the rock blocking the entrance will break. Now you can enter the cave and unlock the Lost Valley Domain!
