Get used to the controls of the Divine Beast and study the map for a bit to get a feel for the level. Next, head inside the area and use the Sheikah Slate to acquire the divine beast dungeon map. Use the Cryonis on the gate to raise it from the water below. Either way, this is still a neat Breath of the Wild discovery nonetheless. Start off the dungeon and defeat the drone inside then take out your Cryonis Rune. Perhaps if DudeBro used like a crate or a log then they could've reached Vah Medoh faster. Octo Balloons don't lift objects with too much and considering the edit in the video from when DudeBro's climb first started, they were probably waiting for a very long time. It is a shame that DudeBro's creativity (and probably also their patience) went unrewarded in this instance. It would seem then that when players actually make it to the Vah Medoh dungeon that it brings in a more detailed version of the Divine Beast as when DudeBro is clipping through this version, none of the actual stage is visible. One would expect the underside of the wings and perhaps the head of Vah Medoh to be detailed, but the stone pillars and intricate ancient carvings on Vah Medoh's wings are visible here as well. Interestingly, as DudeBro's video shows, this version of Vah Medoh is still modeled quite intricately even though players will likely never get as close a look of it as in this video.
