The Ascending Passage connects the Descending Passage to the Grand Gallery. It is {{convert|75|royal cubit|m+ft|1|bits (|)|abbr=on|disp=x}} long and of the same width and height as the shaft from which it originates, although its angle is slightly lower at 26°6'.{{sfn|Dormion|2004|p=286}}

The lower end of the shaft is plugged by three granite stones, which were slid down from the Grand Gallery to seal the tunnel. They are {{convert|1.57|m|ft|abbr=on}}, {{convert|1.67|m|ft|abbr=on}} and {{convert|1|m|ft|abbr=on}} long respectively.{{sfn|Dormion|2004|p=286}} The uppermost is heavily damaged, hence it is shorter. The Robbers' Tunnel terminates slightly below the stones, so a short tunnel was dug around them to access the Descending Passage, since the surrounding limestone is considerably softer and easier to work.

Most of the joints between the blocks of the walls run perpendicular to the floor, with two exceptions. Firstly, those in the lower third of the corridor are vertical. Secondly, the three girdle stones that are inserted near the middle (about 10 cubits apart) presumably stabilize the tunnel.{{sfn|Maragioglio|Rinaldi|1965a|p=114-115}}
