|“Just out of curiosity, why is it they call it the Wailing Alps?”|
“Because when the unnaturally strong wind gusts blow through the canyons, it creates a wailing sound. They say some gusts are strong enough to blow someone clear off the face of the mountain.”
“Right. No trouble at all.”
|— Ronin and Misako, "Peak-a-Boo"|
The Wailing Alps is the tallest mountain in Ninjago. According to Zane, it is over ten miles high. It is the only area high enough for one to reach the Blind Man's Eye, though a vehicle of some kind is required to ascend it due to its unstable slopes. Near its summit, the Hanging Temple is constructed.
Needing to access the Cloud Kingdom through the Blind Man's Eye, Morro, Bansha, Ghoultar, and Soul Archer traversed up the Wailing Alps in order to use its massive peak to reach the entrance. However, the Ninja, following in their individual mechs, attracted the attention of the four Ghost Warriors, forcing Bansha to unleash a sonic scream and trigger an avalanche that destroyed three of their mechs and nearly killing the protagonists. However, her efforts would be for naught when the Ninja, with the aid of Cole, managed to traverse the mountain in record time once more and catch up to the Ghosts, battling at the Hanging Temple. Eventually, with Blind Man's Eye passing over the peak, the Ninja used Airjitzu to access the Cloud Kingdom, leaving the mountain.
Exiting from Blind Man's Eye and escaping the pursuing Ghost Warriors, the Ninja would take advantage of the downward slope to slide down on their stolen Cloud Kingdom boat, eventually riding on its fragments after it was shattered by a stone jutting out of the mountain. Meeting initial conflict with the Ghosts in the chase, the Ninja succeeded in escaping with the Sword of Sanctuary, forcing both parties to abandon the mountain.

- When winds blow through the mountains, it sounds similar to a wail, hence the name.
