Okay, so I’ve been putting a ton of hours into Baldur’s Gate 3, just like everyone else, it seems. At some point, deep into the game, I started wondering, you know, how much more is there? Like, how is this massive thing structured? I needed to figure out how many acts are actually in BG3.

My first step, naturally, was just playing. You get these big transition moments in the game, right? Moving from the early wilderness area into that dark, cursed place definitely felt like a shift. That felt like Act 1 ending and Act 2 beginning. It was a pretty clear change in scenery and tone.
Then, after spending ages in the spooky lands, dealing with all that shadow stuff, eventually, the story leads you towards the big city itself, Baldur’s Gate. Getting there felt like another major milestone. So, hitting the city gates, I figured, okay, this must be Act 3.
But here’s where I got a bit fuzzy for a while. Act 3 is HUGE. Seriously, the city is massive, and there are so many quests and areas packed into it. It felt so much bigger than the previous areas, it almost made me wonder if it was split into multiple acts itself, or if maybe there was an Act 4 hiding somewhere after the main city plot.
My Search and Findings
So, I paused my game. I started asking around in forums and chats where I talk with other players. Some people had similar thoughts, wondering if the scale of the final part meant more acts. There was a bit of chatter, especially early after release, about maybe four acts or the structure being unclear.
To get a clearer picture, I did some digging online, trying to find official word or consensus from people who’d finished the game multiple times. I specifically looked for how the developers, Larian, talked about it or how the game files might be structured (without spoiling story details for myself, of course!).

What I consistently found, and what matched my own progression through the game’s big turning points, was this:
- Act 1: This covers the initial wilderness area, the Druid Grove, the Goblin Camp, the Underdark, all that early exploration stuff.
- Act 2: This is centered entirely around the Shadow-Cursed Lands, dealing with the Ketheric Thorm storyline and locations like Moonrise Towers and the Last Light Inn.
- Act 3: This kicks off when you finally arrive at Baldur’s Gate proper and encompasses the entire city and its surrounding areas, leading up to the final confrontation.
Wrapping it Up
So, based on my own playthrough experience, the major story beats, the environmental shifts, and what the general consensus seems to be, Baldur’s Gate 3 is structured into three distinct acts. Act 1 is the introduction and exploration, Act 2 is the dark middle chapter, and Act 3 is the sprawling urban conclusion.
Even though Act 3 feels gigantic compared to the others, it really is just one continuous act leading to the game’s ending. There isn’t a hidden Act 4 after you reach the city. It’s a solid three-act structure, just like many classic stories and RPGs. That’s what I found through my own playing and digging around. Hope this helps anyone else wondering the same thing!
