This first one isn’t exactly a “point of no return”, since you’ll still freely be able to return to previous areas prior to this point. However, it’s still a point worth noting, becauseprogressing past this point will lock you out of the following contentif you haven’t completed it by this point:

Mountain Pass

In order to get to the Mountain Pass, you’ll need to travel to thefar west of the map,past Waukeen’s Rest (X:-79, Y:572). You’ll eventually come across acutscene of a githyanki patrolterrorizing and massacring a group of Flaming Fist soldiers.

You’ll have todeal with the githyanki patrolby fighting or talking them down; after which you’ll be able to progress further east into the Mountain Pass.

Once at Grymforge, you’ll find yourself sucked into a crisis whereinNere, a True Soul, has been trapped by a cave-in. You’ll be able to choose tohelp him massacre the outpost in retaliation, orrescue several deep gnome slavesfrom his ire—the latter of which willgrant you the loyalty of Barcus Wroot(and his excellent gloves).

Regardless, after this, you’ll be able to take the elevator in the outpost into the shadow-cursed lands.

Grymforge is a huge area full of secrets, such as theAdamantine Forgeand theSentient Amulet. Make sure to take your time and explore before progressing!

Act Two Point Of No Return

This one, on the other hand, is definitely a point of no return, andwill lock you out of all Act One locations,including that of theMountain Pass and Underdarkonce you progress past it.

In addition, it will also lock you out of orautomatically fail certain side quests,such as saving Wulbren and the tieflings. ensure you’vedone everythingyou want to do before progressing past this point.

This point lies in theGauntlet of Shar, deepunder theGrand Mausoleum(X:-174, Y:79)in the shadow-cursed lands of Act Two.

After passingall the trials in Shar’s Gauntlet,you’ll be faced with a pool of water that teleports you to the Shadowfell and has youfacing off Balthazar and the Nightsong. Going through this portal will mark the second point of no return.

Act Three Point Of No Return

This point of no return is thetransition between Act Two and Three, and occurs after you choose to progress to the city of Baldur’s Gate. This point willlock you out of all areas prior to Act Three—this means anything in Act Two, Act One, the Underdark, or the Mountain Pass.

If you haven’tlifted the shadow curse yet, you will also lose Halsin as a companion permanently.

you may do so by traveling to thefar west of the shadow-cursed lands of Act Two—northwest of the Moonrise Towers (X:-151, Y:-96) and southwest of the Grand Mausoleum (X:-174, Y:79) .

If you angered Vlaakith at the Githyanki Creche, you’llface off an Avatar of Vlaakithalong this path, just before the waypoint. Be prepared for a tough fight before you embark.

Be warned: trying to progress to this pointbefore dealing with Ketheric Thorm and the Nightsongwill find you facing off the armies of the Absolute.

Your companions will warn you against brute-forcing your way through them, and if you disregard their warnings, you’ll quicklyfind yourself thrown into a cell under Moonrise Towers. Baldur’s Gate 3 offers remarkable freedom in most areas, but you’ll need to follow the main storyline on this one.

Taking The Skiff In The Sewers Of Baldur’s Gate

The final point of no return happens when you take the skiff to challenge the Netherbrain, with said skiff being hidden in the labyrinthian depths of Baldur’s Gate’s sewers. Once you have collected all three Netherstones, you’ll be able to journey to your final challenge, but it isn’t just a single fight.

You won’t be able to change your party once you board the skiff.

Boarding the skiff will make you leave Baldur’s Gate behind, abandoning any ongoing quests you were doing there. As such, you should finish any business you have in the city since all those quests can turn into added help for the final battle, either against the forces of the Absolute or against the terrifying Brain itself.
