You finally made it. After surviving the shadow-cursed lands and kicking Ketheric Thorm’s teeth in, you’re looking at the sprawling, chaotic mess that is the BG3 Act 3 map. It’s massive. Honestly, the jump in scale from Act 2 to the Lower City is enough to make anyone want to close the game and take a nap. You go from a linear, gloomy path to a dense urban sprawl where every single door seems to lead to a quest that’ll take you four hours to finish.
Baldur’s Gate isn’t just a city; it’s a giant puzzle of verticality and hidden basements. If you try to explore it like a normal RPG, you're going to miss half the content.
The biggest mistake people make is thinking the BG3 Act 3 map is one continuous space. It's not. It is essentially split into three distinct zones: Rivington, the Lower City, and the endgame areas like the Sewers and the High Hall. Each one feels different. Rivington is a dusty, refugee-filled outskirts area that feels like a natural extension of the road you've been traveling. But once you cross that bridge into the Lower City? Everything changes. The density triples.
Navigating the Chaos of Rivington
Rivington is your welcome mat. It’s deceptive. You think, "Oh, this isn't so bad," while looking at the circus and the windmills. But even here, the BG3 Act 3 map starts hiding things in plain sight.
Take the Circus of the Last Days. It’s right at the start. Most players go in, talk to the clown, and maybe get into a fight. But if you aren't poking into the back corners, you're missing the Djinni who can teleport you to a literal jungle. That’s the thing about Act 3—the map says you're in a city, but the game is constantly trying to pull you into pocket dimensions.
Then there’s the Open Hand Temple. It looks like a standard "investigate a murder" trope. But the map doesn't show you the layers. You have to find the hatch, get into the caves underneath, and suddenly you realize the geography of the city is stacked like a lasagna. If you aren't checking your Z-axis, you aren't really playing.
The Wyrm’s Crossing Bottleneck
Before you even get to the "real" city, you hit Wyrm’s Rock Fortress. This is the gatekeeper of the BG3 Act 3 map. It’s a vertical fortress. You can’t just walk through the front door unless you’ve got a pass or you’re ready for a bloodbath.
Pro tip: Look at the cliffs. There’s a path to the right of the main bridge that lets you scale the side of the castle. Larian Studios loves rewarding players who treat the map like a jungle gym rather than a road. You can find the Wyrmway down here too, but good luck with the trials if you haven't been paying attention to the lore. It’s deep. Like, actually deep underground.
The Lower City: Where the BG3 Act 3 Map Gets Overwhelming
This is it. The big one. The Lower City is a labyrinth of shops, houses, and sewers. It’s where the "quest log bloat" happens.
You step through the gates and your map instantly fills up with twenty different icons. It’s tempting to just follow the markers, but that’s how you get burnt out. The BG3 Act 3 map rewards curiosity more than completionism.
One of the most complex parts of this area isn't even on the surface. It's the Sewers.

The Sewers act as a second map layered underneath the Lower City. It’s how you access the Undercity Ruins and eventually the Temple of Bhaal. If you get lost—and you will get lost—just remember that almost every manhole cover in the streets leads down there. It’s a fast-travel network for people who hate guards.
Key Landmarks You’ll Actually Need
- Sorcerous Sundries: Right in the middle. You can’t miss it. It’s the big magical tower. Go here if you want the best spells or if you’re following Gale’s story.
- The Elfsong Tavern: Your home base. You can actually rent the top floor as a camp. It makes the BG3 Act 3 map feel a lot more manageable when your "camp" is a physical building in the world rather than a weird pocket dimension.
- The Counting House: South side. It’s a bank. High security. If you’re looking for Minsc, you’ll end up here. The map makes it look like one building, but the vaults go deep.
- House of Hope: Okay, this technically isn't on the "map," but you access it through the Devil’s Fee in the north. It’s arguably the best dungeon in the game.
People often complain that the performance drops in the Lower City. They're right. It’s because the game is tracking hundreds of NPCs at once. If your PC is screaming, try turning down the "Crowd Density" setting. It won't change the map layout, but it’ll make walking across it a lot smoother.
Dealing with the Verticality and Hidden Layers
One thing the BG3 Act 3 map is terrible at showing is height.
You’ll see a quest marker and stand right on top of it, but there’s nothing there. Check the roofs. Or the basement. In Act 3, "exploration" usually means finding a way to get onto a balcony or breaking through a weak floorboard.
Take Cazador’s Palace. It’s tucked away in the North-West, built into the very walls of the city. You access it by climbing a guard tower. If you’re just looking at the street level, you’ll never find it. Same goes for the House of Grief. The map shows a relatively small building, but the Sharren cloister underneath is massive.
The Undercity and the Temple of Bhaal
This is the "Basement of the Basement." To get here, you have to navigate the Sewers until you find the door that requires a blood sacrifice (or just a very specific amulet).

The Undercity Ruins are a straight-up combat gauntlet. The map here is much more linear than the city above, which is honestly a relief by the time you get there. It leads to the Temple of Bhaal, which is the climax of Orin’s storyline. It’s dark, it’s creepy, and it’s a long walk back if you forget to hit the fast travel point.
Essential Tips for Map Management
If you want to survive the BG3 Act 3 map without getting frustrated, stop trying to do everything at once.
Pick a neighborhood. Stay in the "Heapside" area until you’ve cleared those quests. Then move to the "Central Wall" area. If you bounce from the South Span to the Bloomridge Park every five minutes, you’ll spend half your time in loading screens.
Also, talk to the NPCs. I know, there are too many of them. But in Act 3, the map updates based on "rumors." You might find a whole new basement or a hidden entrance just because you bothered to talk to a cat or a random beggar.
The map is a tool, but in Baldur’s Gate 3, it’s also a bit of a liar. It shows you the shell of the city, but the meat is in the interiors. Don't be afraid to break into houses. Most of them have something worth finding, whether it's a piece of legendary gear or just a really weird diary that explains why there are so many explosive toys in the city.
Breaking the Map
You can actually bypass huge chunks of the BG3 Act 3 map using spells.
- Fly and Misty Step: These are your best friends. Half the locked gates in the city can be bypassed by just flying to a balcony above them.
- Gaseous Form: Great for getting into the tiny pipes that lead into the Sewers or the Counting House vaults.
- Invisibility: The guards in Act 3 are everywhere. If you’re tired of being stopped every five feet on the map, just go invisible.
The endgame map—the High Hall—is a different beast entirely. It’s a "point of no return." Once you trigger that final sequence, the rest of the BG3 Act 3 map becomes inaccessible. Make sure you’ve finished the personal quests for Shadowheart, Astarion, and Lae'zel before you head toward the Morphic Pool.
Actionable Steps for Your Act 3 Run
To make the most of your time in the city, follow this rough order of operations:
- Unlock the Elfsong Tavern Camp: It’s centrally located and makes managing your party way easier than the generic wilderness camps.
- Get the Lower City Pass: Don't fight the guards at the bridge unless you're doing a chaotic run. Complete the "Solve the Open Hand Temple Murders" quest to get a legitimate pass into the city.
- Prioritize Fast Travel Points: The moment you enter a new district, sprint until you find the purple sigil on the ground. The Lower City is huge, and you don't want to walk from the docks to the North Wall every time.
- Use the Sewers for Stealth: If you have a high bounty or you've pissed off the Steel Watch, use the sewer map to move between the east and west sides of the city undetected.
- Check the "Devil’s Fee" early: Even if you aren't ready for the House of Hope, the shopkeeper there sells some of the best gear in the game and provides the "map" to the Hells.
The BG3 Act 3 map is a lot. It’s messy, it’s dense, and it’s occasionally confusing. But it’s also the most detailed urban environment ever put into a CRPG. Take it slow, look up often, and remember that if a door is locked, there’s almost always a hole in the roof nearby.
