Themes and Navigation
Unlike the previous six dungeons in the game, City in the Sky is not set in Hyrule, but in the heavens, where another civilization can be found. When exploring the high altitudes and braving the gusting winds of the City, it is best to use caution near ledges, grapples, thin walkways, and towers (by using a slow and steady pace); where wind blows, Link can use the Iron Boots to avoid being sent to the world below. After Link obtains the second Clawshot, exploration is made easier, as the young hero can now climb between walls, hold on to Peahats, and moving walls to advance. The city runs on many ancient and complex machines that are far more advanced than anything found in Hyrule. These machines use the power of the wind to its full extent. Wind is the fuel of the city; it powers every major machine that Link comes across.

The Double Clawshot is found inside it after defeating the mini-boss, an Aeralfos. The Iron Boots are also used often in this windy dungeon. The dungeon's boss is the Twilit Dragon, Argorok.

Link's Crossbow Training
The City in the Sky appears in two stages of Link's Crossbow Training. The first as a Target Shooting Mode scenario in Stage 5. Oocca fly across the screen carring targets. Link moves to a new view after each 20 second phase of the level, however, there is no remarkable difference among them.

The second as a Defender Mode scenario of Stage 7. It takes place in the same area as the Argorok battle in Twilight Princess, with many Aeralfos instead of an Argorok. Link stays in a fixed position, but must search all 360 degrees, high and low to hunt down the aeralfos. The aeralfos can be grounded by shooting their wings off, but their shield is capable of blocking most oncoming shots. Alternatively Bomb Arrows can destroy them in a single hit.

Trivia

 * The City in the Sky is unique in the fact that it is the only dungeon with a shop.
 * The City in the Sky is very similar to the Palace of Winds found in The Minish Cap. Although two separate races created each city during different time periods, they share a common bond that is as mysterious as the wind that links them.
 * The City in the Sky has a strong resemblance to the fictional country Laputa from the book Gulliver's Travels by Jonathan Swift. The movie Castle in the Sky by Hayao Miyazaki, features a floating city, that was once home to an ancient civilization of people, who established a kingdom there, however was lost due to war and it's King's wrongdoings. The City in the Sky's design may have been based around Laputa of the same name, of which there are various paintings depicting an artists impression of what Laputa may look like.
 * In Skyward Sword there is a floating kingdom called Skyloft. It may have been thematically inspired by the City in the Sky.
