Crystal Crossing (Japanese: だいすいしょうのみちBig Crystal Road) is a dungeon in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness, and Pokémon Mystery Dungeon: Explorers of Sky. It is unlocked after clearing Crystal Cave, which was unlocked by turning the three crystals blue. It has 13 floors (14 if Crystal Lake is included). Crystal Lake (Japanese: すいしょうのみずうみCrystal Lake), referred to as Shining Lake in British English versions, is where the player battles Grovyle on their first visit. After the first visit, it cannot be revisited until after the end credits, where Azelf is the boss and will be recruited upon defeat.
The jobs here are ranked E, S, A and ★1 by default, depending on the floor.
The floors are either medium or large sized, with 3 to 7 rooms. The size switches every floor except 3, 5, 8 and 10, with floor 1 being medium-sized. The game will spawn 1-4 items on floors 1 through 4, and 2-5 on later ones. There's usually 2-3 starting enemies on floors 1 through 8, and 2-4 on later floors.
The IQ Booster activates on odd floors past the 1st one. The turn limit is 1000. The enemies in this dungeon have 26IQ, granting them Status Checker IQ skill. There is water in the dungeon.
Winning against Grovyle is not mandatory. The player will not be teleported out of the dungeon and the story will progress either way.

Trivia
Despite the story proceeding as usual even if the player loses to Grovyle, it is treated as any other defeat in the base games, Explorers of Time and Darkness, resulting in a loss of items and money. This was changed in Explorers of Sky, where a loss does not result in item/money loss.
This is the final Dungeon that Pokémon can be recruited in before the credits
