How to get to Underdark in BG3

There are four entrances to the Underdark from the surface map in the first Act of the game! Some are easier to find than the other though. There is also an elevator in Grymforge that connects the Underdark with Shadow Lands in Act 2. You can use that Elevator from the Underdark to advance to Act 2 or enter Underdark if you have not already. You can find the Entrances to get to Underdark in the following locations:

  • Blighted Village – Whispering Depths
  • Goblin Camp – Defiled Temple
  • Waukeen’s Rest – Zentarim Hideout
  • Riverside Teahouse – Auntie Ethel’s
  • Shadow Lands -Entrance to Underdark

Whispering Depths Underdark Entrance in Baldur’s Gate 3

This is probably the first Entrance to Underdark that you will find in Baldur’s Gate 3. When you first visit the Blighted Village you can interact with the Well in the center of the area. By doing this you will descend to the Whispering Depths area. The area is full of hostile Spiders that you need to defeat. Once you have dealt with the Spiders head towards the Chasm nearby with a green glow!

Whispering Depths Underdark Entrance

The Chasm is connected to the Underdark and if you jump inside you will land near the Phalar Aluve Longsword location. However in order to survive the jump you will need to use a “Feather Fall” spell to your party. Otherwise you will die and it will be Game over.

Defiled Temple Underdark Entrance in BG3

The next entrance to the Underdark is located inside the Goblin Camp to the West of the map. You will eventually find yourself in the Goblin Camp in an effort to save Halsin(or betray the Grove if you wish). Once you get inside the Shattered Sanctum, find Priestess Gut. You can fight or persuade her in order to let you in the Priestess Private Room.

Shattered Sanctum

From there you can head to the Defiled Temple where an easy puzzle is waiting for you. Solving the Puzzle will open a hidden area with a ladder that will take you all the way down to the Underdark.
