Pass through the small path near the ravine. Dismount Agro and dive into the water. Swim your way to the collapsed wall. Go forward and up the set of stairs.

When she’s beside you, mount her by pressing ∆. The beams should centralize on the east side of the shrine. You'll notice there's a ravine and a small path beside it (near the place you entered through while going to the fourth colossus).

Press R1 to dive underwater and go through it. Go towards the wall and scale it by pressing ∆. Press R1 to grab on the ledge. A cutscene will play showing you the fifth colossus.  This will cause Avion to fly up to the skies. Prepare for battle!
