You’ve just crawled out of a crashed nautiloid. Your brain has a parasite in it. The beach is covered in dead mind flayers and aggressive intellect devourers, and honestly, you're probably just trying to find a save point. But then you hit 'M'. Looking at the bg3 act 1 map for the first time is actually pretty overwhelming because Larian Studios didn't just build a level; they built a dense, vertical labyrinth that hides half its content behind crumbling walls and "low ground" perspectives.
Most players think they’ve seen Act 1 because they reached the Druid Grove and killed some goblins. They haven't. Not even close.
The map is a deceptive beast. It looks like a standard RPG zone, but it's actually three distinct layers stacked on top of each other. You have the surface wilderness, the claustrophobic depths of the Underdark, and the jagged heights of the Mountain Pass. If you’re rushing toward the towers in the distance, you’re going to miss the best loot and the weirdest stories in the game.
The Surface Wilderness: More Than Just Goblins
The initial stretch of the bg3 act 1 map is designed to distract you. It pulls you toward the Emerald Grove and the Blighted Village. These are the "obvious" beats. However, the real meat of the surface map is in the corners people usually ignore because they’re too busy worrying about the ticking clock of the tadpole in their skull.
Take the Sunlit Wetlands to the south. At first glance, it’s a beautiful, swampy meadow. If you pass a passive investigation check, the illusion shatters. It turns into a fetid, corpse-ridden bog. This is where Auntie Ethel lives. Her tea house is a landmark, sure, but the map doesn't tell you that her basement leads to a portal that spits you out halfway across the world.
Then there’s the Risen Road. You have to jump a broken bridge to get there. Most people see the gap and just turn around. Don’t. That northern strip of the map holds the Waukeen’s Rest inn—which is currently on fire—and the entrance to the Zhentarim Hideout. If you don't explore that specific smudge of brown on your mini-map, you lose access to some of the best early-game titan-string bows and specialized thievery gear.
The verticality here is insane. You’ll be walking along a path, look up, and realize there’s an entire gnoll war band on a ridge thirty feet above you. If you aren't rotating your camera constantly, you are playing half a game.

The Underdark is the Real Heart of the Map
A lot of players ask if the Underdark is Act 2. It’s not. It’s still part of the bg3 act 1 map ecosystem, and it is massive. You can get there four different ways: the pit in the Whispering Depths (wear Feather Fall, seriously), the elevator in the Zhentarim hideout, the puzzle in the Goblin Camp, or the portal in Ethel’s basement.
It's a bioluminescent nightmare.
The Underdark is divided into several sub-regions that don't always connect in the ways you'd expect. You’ve got the Myconid Colony in the north, which is basically your only "safe" hub. To the southwest lies the Arcane Tower. This place is a vertical puzzle. You have to power up an elevator using Sussur flowers just to see the whole thing.
Then there’s Grymforge.
Grymforge is technically the end of the Underdark section, accessible via a boat ride across a dark lake. It feels like a separate zone entirely. It’s a crumbling Sharran fortress built over a lake of lava. This is where the Adamantine Forge sits. If you don't find the specific hidden ledges and moving platforms, you’ll never find the molds required to craft the best heavy armor in the first thirty hours of the game. It’s easy to get lost here because the map overlay struggles with the multiple floor levels. Use your tactical view.
Why the Mountain Pass Isn't a Point of No Return
There’s a common misconception that entering the Mountain Pass "ends" Act 1 or locks you out of the rest of the bg3 act 1 map. It doesn’t. It’s a side-step. You can go there, do the Crèche Y'llek storyline, and come right back to the Druid Grove if you want (provided you haven't progressed the main conflict to a boiling point).

The Mountain Pass is smaller than the wilderness or the Underdark, but it's much denser. It’s where you find the Rosymorn Monastery. This location is a masterclass in level design. It’s a ruined holy site that houses a literal githyanki army in its basement.
The map here is treacherous. It’s all narrow cliffside paths and cable cars. If you’re looking for the Blood of Lathander—a legendary mace that basically makes the next ten hours of the game a cakewalk—you have to solve a statue puzzle that the map doesn't give you any hints for. It’s all about environmental storytelling. Read the plaques. Look at the paintings.
Missing the "Secret" Pockets
There are parts of the map that aren't marked with icons until you're standing on top of them.
- The Whispering Depths: Located under the well in the Blighted Village. It’s a spider-infested hellscape that holds the key to the Necromancy of Thay.
- The Festering Cove: Tucked away in the Underdark. You have to climb down a specific cragged rock wall near the beach. There’s a whole cult of fish-people worshipping a fake god down there. Most players miss it entirely.
- The Hidden Vault: Inside the Emerald Grove, behind a stone door you can only open with a specific wolf rune. It’s not on the map until you’re inside.
Larian uses "fog of war" aggressively. Just because a section of the map looks like "solid mountain" doesn't mean it is. Often, it's just a texture hiding a cave entrance or a climbable vine.
Navigating the Map: Expert Tips
Stop relying solely on the quest markers. The bg3 act 1 map rewards curiosity more than it rewards following the golden trail. If you see a patch of black on your map, go there.
Jump. Just jump everywhere.

Many of the map's best secrets are separated by small gaps that the pathfinding AI won't automatically navigate. If you see a ledge across a stream, manually jump your character over. Often, you'll find a heavy chest or a unique interaction.
Also, use the 'O' key for the tactical overhead view. The standard third-person camera is great for immersion, but it's terrible for understanding the layout of complex areas like the Goblin Camp or Grymforge. The top-down view reveals paths and doors you might have walked past five times.
Actionable Steps for Completionists
If you want to ensure you've actually cleared the map, follow these steps before moving on to the Shadow-Cursed Lands:
- Check the "completion" of your map by looking for the "Leave for a different region" icons. You should see two major ones: the elevator in Grymforge and the road at the end of the Mountain Pass.
- Locate the three "hidden" bosses of Act 1: The Phase Spider Matriarch (Blighted Village depths), the Spectator (Underdark near the Selunite Outpost), and Grym (The Adamantine Forge). If you haven't fought them, you haven't seen the whole map.
- Ensure you've found all the fast travel waypoints. There are roughly 15-18 in the first act alone, depending on how you categorize the sub-regions.
- Visit the Zhentarim Hideout and the Myconid Colony. These are the two biggest "neutral" hubs that offer unique vendors and quests that significantly expand the map's lore.
- Check the southern coast. Many people forget the river area south of the starting beach where you meet a certain monster hunter and find some very angry wood woads.
The beauty of the map isn't in its size, though it is quite large. It’s in the density. Every inch of it has been touched by a level designer. There is no "filler" terrain. If a hill looks like you can climb it, you probably can, and there's probably a skeleton with a diary at the top.
Go back. Explore the black spots. You’ll be surprised at what’s still waiting for you.
