The Wu Dan Mountains (or Wudang Mountains) is a small mountain range located within the Valley of Peace.
The tranquil mountain range hosts a variety of lush green fields, unusually shaped boulders and forests. It also features the Pool of Sacred Tears.
A thousand years ago, Oogway left his home in the Galapagos Islands and traveled all over the world. He eventually reached the Wu Dan Mountains in China, where he discovered a tranquil pool. It was here that Oogway observed the plight of the oppressed and invented Kung Fu to help fight off the evil in China. The pool became known as the Pool of Sacred Tears, the birthplace of Kung Fu.Shifu trained Po in the art of Kung Fu. After having discovered that Po could be trained using food as motivation, Shifu took the panda into the mountains and showed him the Pool of Sacred Tears. After much vigorous training, including push-ups and ten-mile hikes, Po eventually became a skilled Kung Fu warrior.
- According to the filmmakers' commentary on the Kung Fu Panda DVD (as well as The Art of Kung Fu Panda), the Wu Dan Mountains were based off of the Wudang Mountains (or "Wu Tang Shan"), a small mountain range located in the northwestern part of the Hubei Province in China. Its history with Taoism regards it as the actual birthplace of Chinese martial arts.
- The filmmakers also pointed out in the Kung Fu Panda DVD commentary that Wu Dan is most likely where Oogway trained young Shifu.
- The Wu Dan Mountains were meant to provide a spiritualistic alternate training ground in contrast to Master Shifu's militaristic Training Hall.
- The Wu Dan Mountains are also a notable location in the virtual online game Kung Fu Panda World, though it is referred to as a single mountain, "Wu Dan Mountain". The area can be found in the Birth Place of Kung Fu and is a popular area amongst online players.
