Is there a way to get up short ladders?

[Sword of Spirit]

I know that sometimes you can only go down them, but I'm in the Venom Depths looking at a ladder going up to an plateau with no other means of getting there. That isn't the only place I've seen this sort of thing, so I'm wondering if there is some sort of item you get that lets you climb up these ladders, or if you just can't get to them and they are just there to taunt you, or if every one has it's own unique way (like getting teleported there from somewhere else).

I think all of them can be reached definitely(no climb up).
