Navigating to the Underdark is one of the most pivotal milestones for adventurers exploring the sprawling wilderness of Act 1 in Baldur's Gate 3. This massive subterranean realm lies deep beneath the surface and contains crucial story progression paths, powerful loot, and unique encounters. Understanding the various entrance routes allows players to choose a path that best fits their current party level and playstyle.
The Defiled Temple Passage Beneath the Goblin Camp
One of the most straightforward ways to access the Underdark is through the Defiled Temple located inside the Shattered Sanctum. Players must venture past Priestess Gut's quarters and solve a stone disk moon puzzle to unlock the hidden hatch. Descending through this portal leads directly to a Selûnite Outpost equipped with defensive waypoints and statuary protection.
Descending Through the Whispering Depths Chasm
For daring adventurers, the chasms within the Blighted Village offer an unexpected shortcut into the deep cavern network. After dealing with the Phase Spider Matriarch in the Whispering Depths, players can cast Feather Fall on their party members and jump straight down the glowing green pit. This dramatic drop lands the party directly in the middle of the Underdark near the Minotaur territory.
Unlocking the Zhentarim Hideout Elevator
A hidden mechanical elevator located inside the secret Zhentarim Hideout near Waukeen's Rest provides another convenient entry point. Players can gain access by aiding the Zhentarim mercenaries or lockpicking their way into the back storage room behind an illusory wall. Activating the hidden lift transports the party safely down near the Dread Hollow region of the subterranean map.
Navigating the Teahouse Portal in the Overgrown Tunnel
The mysterious lair of Auntie Ethel in the Sunlit Wetlands conceals a subtle, magical portal leading straight into the abyss. By equipping a Whispering Mask or using jump spells, players can pass through the giant wooden face inside the Overgrown Tunnel. This portal teleports the group onto a high stone ledge near the Underdark's Festering Cove area.
