Mountain pass or grymforge elevator

[Character Name]

I've completed everything in Act 1 that I want to complete, and am ready to travel on -underdark and grymforge are completed where possible. Can I backtrack to the mountain pass, go to the creche, and then come back to the Grymforge elevator without problems? Or is it best to take the elevator, then go back to the Creche in the pass?

Mountain Pass is still Act 1, and you can go back from it at any time.

Yes, you can go to creche and then come back and use elevator.

[Character Name]

Oh thanks - it just warned me when I tried to go through it that I had best have everything cleared before proceeding.

If you go through the Elevator to act 2, you won't be able to come back, but you can leave the way you came in and go to the Creche through the mountain pass, and that's still in act 1.

You can do both, I cleared Underdark and Forge first, followed by mountain pass.

...um... I did.

I only came back after I had spoken to Elminster, and then did the creche... a bit of a completionist urge in me.
Technically the mountain pass is also act 2... act 2 just doesnt have as hard a wall behind as you might think.

At first I just teleported back to sell stuff to a vendor i KNEW was at max... but then I figured I'd do the other way, get the loot/exp. Well worth doing both.

That's a negative.

You can start act 2 and then go back and do mountain pass\creche without issue.

I'd assume the same is true of the underdark but haven't done it that way personally.
