We had to run up and down ladders two or three times just to reach the top.
Luxury !
Back in my days, we would have called ourselves lucky if the ladders didn't break when we tried to use them.
We used to throw some of our party members up to the ledge if we could, and the other would use Misty Step or Badget teleportation.
Ropes ? What do you mean ropes ? Sure we found some, like everyone, but ours could not be used to climb up and down.
