This cave is initially accessed during the quest "Touching the Sky" by help of the Snow Elf Knight-Paladin Gelebor. Gelebor will open one of the shrines for the Dragonborn, who, after travelling through it, ends up in Darkfall Passage.
- Darkfall Passage is one of the two locations that the Dragonborn will encounter the new flora and fauna introduced in The Elder Scrolls V: Dawnguard, including vale deer, vale sabre cat, gleamblossom, yellow mountain flower (can also be found in other areas as well) and poison bloom.
- The first part of the passage is extremely dark — darker than any other cavern in Skyrim. It can be difficult to navigate without the use of torches, nightvision, or the Alteration spell Candlelight.
