How To Find The Underdark BG3 And Enter The Area

Exploring the sprawling realm of Faerûn in Baldur's Gate 3 leads adventurers to subterranean regions filled with unique encounters and rare treasures. The Underdark is one of the pivotal Act 1 locations that players must navigate to advance toward the Moonrise Towers. Understanding how to locate and safely descend into this subterranean expanse ensures your party is properly equipped for the dangers ahead.

Entering Through the Defiled Temple in the Goblin Camp

One of the most straightforward entry points to the Underdark lies deep within the Goblin Camp inside the Shattered Sanctum. Players can venture into Priestess Gut's private quarters and access the Defiled Temple by lockpicking doors or negotiating passage. Inside the temple, solving the moon dial puzzle on the floor unlocks a hidden passage that leads directly to a ladder going down to the Selûnite Outpost.

Before stepping out into the Underdark from the outpost, make sure to disable the statue's magical defense system by destroying its moonstone. This entry point provides a structured transition and places your team near key early-game subterranean quests.

Using Feather Fall in the Whispering Depths

Another prominent route is located beneath the Blighted Village inside the spider-infested Whispering Depths. Adventurers can access these caverns by descending the central village well or breaking through a cellar wall. Near the lair of the Phase Spider Matriarch sits a massive, glowing chasm that leads straight down into the abyss.

To use this entrance safely, cast the Feather Fall spell on your entire party before jumping directly into the pit. Jumping without this spell will result in instant death for your characters upon impact at the bottom.

Infiltrating the Secret Zhentarim Hideout Elevator

For players who prefer a stealthier approach, the Zhentarim Hideout near Waukeen's Rest features a concealed mechanical lift. Locate the small storage shed covered by wooden crates to find the entrance to their underground lair. Once inside, pass a perception check near the back wall behind the sleeping wolf to reveal an illusory wall.

Walk through the illusion and use thieves' tools to pick the lock on the elevator winch. Riding this wooden lift takes your party down into a quiet section of the Underdark.

Navigating the Portal in Auntie Ethel's Teahouse

The fourth primary pathway is hidden deep within the Sunlit Wetlands inside Auntie Ethel's Riverside Teahouse. Players must move through the fireplace illusion and navigate the treacherous Overgrown Tunnel. After passing through the waterfall, equip a Whispering Mask while protected from evil to pass through the second wooden face door.

Beyond this door lies a secret room housing a green mushroom circle that teleports your party directly into the Underdark. This route requires careful preparation due to the various traps and enemies encountered along the way.
