Baldur's Gate 3 Act 1 Map: The Four Main Regions

The Baldurs Gate 3 Act 1 map splits into four regions, and knowing what each holds saves a lot of aimless wandering early on.

Wilderness

The above-ground core of Act One, linking multiple locations including the Emerald Grove and Waukeen's Rest, connected by the Risen Road. Most of your first companions and quests start here.

Underdark

Reached through openings scattered across the Wilderness — a lightless network of caverns "full of dangerous creatures," home to drow, duergar and deep gnomes, and rich in alchemical ingredients you won't find above ground.

Grymforge

The remains of an ancient fortress built around the Adamantine Forge, currently held by duergar working for the Absolute while they search for a way through to their goal. A dedicated Underdark sub-region rather than a stop along the way.

Rosymorn Monastery

In the northeast. Githyanki have claimed its underground section as Crèche Y'llek, with the monastery grounds above populated by other threats entirely — two very different dangers stacked in one location.

Reading the map

Wilderness first, Underdark and Grymforge as a connected detour, Rosymorn Monastery as its own late-Act-One destination. Treating them as four separate trips rather than one straight line is what the region layout is actually built for.
