Canyon of Awakening is a location within Far Cry 4's Valley of the Yetis addon. It is the first location Ajay comes across following his helicopter crash in the Himalayas.
This is one of the places where the Relic leaves its Elixir (Yellow liquid can be found circulating in the hot springs there) and this is where Sandesh and his soldiers saw a Yeti by themselves for the first time. Sandesh's soldiers bathed in the yellow waters in a cave of the canyon and it was here their transformation began. As the relic’s contaminated water made them hear voices and see maddening visions. Ajay goes there after his helicopter crashes and is trying to rescue his pilot, Sukhwinder. The place is full of Loot Chests with animal skins and other collectibles found in chests in the main game.
While notes left by Sandesh’s soldiers indicate sightings of a yeti. None can be found at this location within the actual game.
Inside the caverns one may find the bodies of acolytes. Originally there practicing their infamous 100 year meditation, but now dead due to natural causes. A disembodied voice can be heard inside saying “awaken” & otherworldly things. Possibly hinting that the spirits of the original disciples inhabit the cave.
