Tianmen Mountain in Zhangjiajie, Hunan Province, China, is home to one of the world’s most breathtaking natural wonders: Tianmen Cave, famously known as Heaven’s Gate. This massive natural arch, often described as a “giant hole” piercing through the cliff, stands approximately 131.5 meters (431 feet) tall, making it the highest natural mountain-penetrating arch on Earth.
What Makes Heaven’s Gate So Unique?
Tianmen Cave is a stunning karst formation with these impressive dimensions:
- Height: 131.5 meters (about 130-135 meters in various sources)
- Width: 57 meters
- Depth: 60 meters
- Elevation: Around 1,300 meters above sea level
Formed in 263 AD when the back wall of a large cave collapsed in a dramatic event (recorded in historical Chinese documents), it transformed the mountain originally called Songliang Shan into Tianmen Shan, meaning “Heaven’s Gate Mountain.” This rare, historically dated natural arch looks like a portal to the heavens, especially when mist or clouds swirl through it, creating the famous “Heaven’s Gate Spitting Clouds” phenomenon.
How to Reach the Giant Hole: The Stairway to Heaven
The most iconic way to approach Heaven’s Gate is via the 999-step “Stairway to Heaven”, a steep escalator-assisted or direct climb symbolizing eternity and good fortune in Chinese culture (the number 9 is auspicious). Crowds of tourists ascend these steps for the ultimate photo op under the arch.
Other thrilling access routes include:
- World’s longest passenger cable car: 7,455 meters long, offering panoramic views during a 30-minute ride.
- Tongtian Avenue (Heaven-Linking Road): An 11 km road with 99 hairpin bends perfect for adrenaline seekers.
- Glass skywalks and cliff paths on the summit for vertigo-inducing vistas.
