Learn how to get to the Underdark in Baldur’s Gate 3 in this guide. The Underdark is only a minor portion of the expansive game Baldur’s Gate 3, which has much to explore. It’s perilous, but intrepid players can discover a few cleverly placed openings and venture into it at least partially very early in Act 1. At some point in the narrative, the protagonist is given the option to choose between going through the Mountains or the Underdark to reach the Shadow-Cursed Lands. You may do both, though, and having a map of the key spots is helpful for anyone who intends to visit the Underdark.
A fantasy adventure wouldn’t be the same without exploring mysterious, shadowy areas. The setting of Baldur’s Gate 3 is Faerûn, and underneath it lies the enormous Underdark subterranean realm. This notorious area has appeared in almost every game set in the Forgotten Realms, including Baldur’s Gate 3. The Overworld map is enormous, and the Underdark is nearly as large. So let’s investigate the best route there. Here are the simple steps how to get to the Underdark in Baldur’s Gate 3.
