The entrance to the Underdark in Baldur’s Gate 3 isn’t just one spot—there are four main ways to get there in Act 1, all leading to the same sprawling underground region.

Quick Scoop

If you’re wondering where is the entrance to the underdark bg3 , here are the four primary routes:

  1. Blighted Village – Whispering Depths well
  2. Goblin Camp – Defiled Temple in the Shattered Sanctum
  3. Sunlit Wetlands – Auntie Ethel’s Teahouse / Hag lair
  4. Waukeen’s Rest / The Risen Road – Zhentarim Hideout elevator

Each one drops you into the Underdark from a different angle, but they’re all Act 1 entrances.

1. Blighted Village – Whispering Depths Route

This is often the first entrance players stumble upon:

  • In the middle of Blighted Village there’s a well you can climb down into; this leads to the Whispering Depths, a spider-filled dungeon.
  • Clear your way through until you reach the Phase Spider Matriarch patrolling near a huge chasm.
  • After dealing with the boss (or sneaking past), cast Feather Fall on your party and jump into the giant pit to reach the Underdark safely.

This path is easy to find , but a bit tougher to survive because of the spiders and the Matriarch encounter.

2. Goblin Camp – Defiled Temple Entrance (Shattered Sanctum)

Often considered the “easiest” structured route if you’re comfortable with puzzles and sneaking:

  • Go to the Goblin Camp and enter the Shattered Sanctum, the big interior goblin stronghold.
  • Head toward Priestess Gut’s private room in the northwest; you can sneak, talk, or fight your way past the guards to reach the locked door.
  • From her room, continue deeper until you reach the Defiled Temple.

There are two ways from here:

  • Solve the moon-tile floor puzzle by rotating the circles so that all the white “moon” symbols are on top and the blackened ones are at the bottom; this opens a hidden passage to a ladder leading to a Selûnite outpost in the Underdark.
  • Or, bypass the puzzle by passing a Perception check to find a hidden lever nearby, then lockpick it to reveal the door down into the Underdark.

This route drops you at a relatively safe, structured starting point in the Underdark, which many guides highlight as friendly for early-game parties.

3. Sunlit Wetlands – Auntie Ethel’s Teahouse / Hag Route

A more “story-heavy” entrance tied to the hag:

  • Travel south to the Sunlit Wetlands and find Riverside Teahouse, where Auntie Ethel resides.
  • Go behind the fireplace into her secret area, then push through the Overgrown Tunnel filled with traps, gas pods, and eerie obstacles.
  • Deal with Auntie Ethel and her captive over a pit—or follow the path through gnarled doors and a mushroom circle that teleports you directly to the Underdark.

Some versions of this route have you jumping down a pit after the fight (with Feather Fall), others use a teleporting mushroom ring beyond her lair; either way, you end up in the Underdark below the wetlands.

4. Zhentarim Hideout – Elevator Route (Waukeen’s Rest / The Risen Road)

This one feels like a secret smuggler shortcut:

  • Head to Waukeen’s Rest, near The Risen Road, and look for a shed or barn with doors blocked by crates; move the crates and go inside.
  • Talk to or bypass the guard (Salazon) using dialogue, a password from the “Missing Shipment” quest, or more… aggressive methods to reach the Zhentarim Hideout.
  • Explore the hideout until your party passes a Perception check near an illusionary wall; behind it is an elevator you can lockpick.
  • Ride the elevator down to arrive directly in the Underdark.

This path is great if you’ve already been doing the Zhentarim-related quests around the Risen Road and Waukeen’s Rest.

Multiple Entrances, Same Underdark

A few helpful notes if you’re deciding which entrance to use :

  • All four entrances lead into the same Underdark region in Act 1, just from different points of access.
  • The Goblin Camp / Defiled Temple route is commonly recommended as the “cleanest” or safest starting spot, especially if you’re not ready for the Phase Spider Matriarch fight.
  • The Blighted Village path is usually the earliest you can reach and doubles as a good test for your party’s readiness.
  • The Hag and Zhentarim routes tie more into side stories and questlines, so they’re great if you’re exploring those narratives anyway.

If you’ve already cleared one of those areas, chances are you’re closer to an Underdark entrance than you think.
