The first nine passes are named 1st Station Pass (Japanese: １ごうめまでのみちのりPath to the 1st Station) to 9th Station Pass (Japanese: ９ごうめまでのみちのりPath to the 9th Station), while the tenth pass is known as the Sky Peak Summit Pass (Japanese: ちょうじょうまでのみちのりPath to the Summit). Each pass has between three and five floors each. Sky Gifts can be found here. The Pokémon in these dungeons begin with Pokémon generally found in Mystifying Forest in the first dungeons, and gradually phasing them out for Pokémon generally found on Mt. Travail. Players can find Hidden Stairs leading to a floor with Treasure boxes. On the Summit Pass, there is a chance of fog, and the Secret Bazaar and Monster Houses may appear on floors 2-5.
A player can only go through this series of dungeons after defeating Primal Dialga and graduating from Wigglytuff's Guild. In the first playthrough of these dungeons, a Shaymin comes with the player. After the first visit, this will unlock the Sky Jukebox.
When reaching the summit for the first time, the place will be covered with filth. To clear it the player needs to defeat three Muk and five Grimer. The Shaymin accompanying the player then absorbs the filth and cleans the place. Team Frontier, a team including a Machoke, Mawile, and a Breloom, helps fight the Muk and Grimer during the first visit.
At the end of each Pass, the player will reach a Station. Each Station has a Kangaskhan Rock with the ability both to save the game and, at the even-numbered Stations, to store items. The one exception is the 5th Station. Upon entering the 5th Station during the first visit, the player will encounter a group of hostile Carnivine which appear to be beating up a Sneasel. The player defeats these Pokémon with the help of Team Frontier. On each following visit, the 5th station is completely empty.
In the even numbered Stations, there is a method of transport called Drifblim's Gondola, where a Drifblim can transport the player instantly between that Station, any previous even numbered Station, and the base camp at Shaymin Village. The only exception to this is the 8th Station, where an Ampharos lives. After finishing the 8th Pass and going into the 9th Station for the second time, the Ampharos will give you a Sky Gift that the Sneasel the player helped left behind.
In many Stations a Pokémon may appear, giving the player a Sky Gift. Occasionally, at a Station, a Pokémon will be in need of an item. If you have said item, you can trade for an item the Pokémon is offering in return, or the Pokémon will return the favor by giving you an item at Spinda's Cafe later.
