If you are in acts 2 or 3 you should have a set of teleporter pyramids. If you use the
armory trick in act 1 procedure to get a summoning doll through the wall, you can have it drop a teleporter and use that to get your main characters through.
It is also possible to edit your characters' locations:
Teleporting anywhere (via hex editor).
Depending on how much of a completionist you are, you could also just skip the rest of the dungeon. I only visited the BF for the merchants, and didn't do any of the dungeons or quests.
