it's accessible.
barely.
use a good 13mm 12 point box wrench, one with a thing 'wall' , like a
snap-on.
you can barely get 1/6th of a turn each time,
and sometimes you have to flip the wrench over each time to get 1/12th of a
'grab' on the nut.
but it'll come off there.

here's a trick...........assuming you have another nut - you unscrew that
hard to access one with a small chisel and hammer.
But you can get it with a good quality box wrench.
