Beijing Icefalls: The Frozen Winter Poem of Earth's Gravity at Black Dragon Pool

Introduction: When Flowing Water Learns to Stand Still

Have you ever truly considered what winter looks like? Not the cold numbers on a weather forecast, nor the cookie-cutter snow scenes on social media—but a frozen beauty that can be touched, gazed upon, and marveled at.

During the Spring Festival of 2023, Beijing experienced a rare deep freeze. Nighttime temperatures plummeted to minus 23 degrees Celsius. On one of those bitterly cold days, I drove alone to Black Dragon Pool (Heilongtan) , a hidden gem nestled in the Yanshan Mountains on the western side of Miyun Reservoir. What drew me there was the promise of the largest and most spectacular icefall in Beijing.

In summer, Black Dragon Pool is a lively symphony of cascading waterfalls and emerald pools. But in winter, it transforms into a visual feast of frozen stillness. Every icicle and curtain of ice tells the purest story of Earth's gravitational pull. This is the ultimate Beijing winter travel guide for those seeking raw, natural beauty.

Chapter One: Frozen Time – The Birth of an Icefall

How Icefalls Form in the Yanshan Mountains

Located between Yunmeng Mountain and Miyun Reservoir, Black Dragon Pool is a canyon roughly four kilometers long, with a vertical drop of 220 meters. This gorge is famous for its eighteen named pools—Spring Blossom, Autumn Moon, Flat Sand, Falling Geese, and more. Each name carries the essence of the changing seasons. In winter, these pools and waterfalls join together in a magical performance of solidification.

When temperatures stay below freezing for an extended period, the once-rushing waterfalls begin to slow. Water pours down the cliff face but is captured midair by the cold, freezing into tens of thousands of icicles. Over time, the ice layers thicken, eventually forming a massive wall of ice. This is how a natural ice wall is born.

What is most astonishing is that an icefall is never completely still. Beneath the thick layers of ice, thin streams continue to flow silently. This state of "stillness on the outside, movement within" gives the icefall a unique vitality. Standing before it, you can hear the faint sound of water under the ice—the last breath of winter. For those searching for frozen waterfall hikes near Beijing, this is a must-see.

Chapter Two: The Art of Gravity – Ice in a Thousand Forms

"Is it the Milky Way falling from the nine heavens?"—Li Bai’s famous lines are no longer just imagination here, but a reality within reach. The icefall cascades down from above like a frozen galaxy, refracting pale blue light under the sun.

If you look closely, you will discover that the icefall takes on countless bizarre and wondrous shapes. Here are the key types of ice formations you will see:

Vertical Icicles: Classic Gravity Art

This is the most classic form of an icefall. Water flows straight down the cliff face, frozen by the bitter cold into rows of icicles. They stand neatly arranged, like a set of keys carefully placed by nature. Each icicle points toward the ground—the most direct proof of Earth’s gravity.

Ice Mushrooms and Ice Forests

In the hollows of the cliff, water forms strange mushroom-shaped ice bodies. Some resemble enoki mushrooms breaking through the soil, with slender ice columns growing upward. Others look like mushroom clouds after an explosion, with ice spreading outward. Even more remarkable are the hair-thin ice threads hanging from some icicles, resembling the mycelium of fungi.

Bubble Ice Layers: The Baikal Effect

The surface of Black Dragon Pool’s ice is a pale blue, astonishingly thick. Countless air bubbles are sealed within the ice, sparkling under sunlight like the blue ice of Lake Baikal. These bubbles are traces of gas trapped during the freezing process, recording every moment of water’s transition from liquid to solid. This is a prime example of blue ice formations in China.

Ice Curtain Caves

Beneath certain waterfalls, the ice forms semi-transparent curtains. Sunlight filters through these curtains, casting dappled shadows on the ground. Stepping inside an ice curtain cave feels like entering a crystal palace. Surrounded by translucent ice walls and with icicles hanging overhead, you cannot help but slow your steps, afraid to break the silence.

Chapter Three: Stories on the Ice – A Dialogue Between Humans and Nature

Icefalls are not only masterpieces of nature but also stages for human emotion. On the frozen surface of Black Dragon Pool, I witnessed some of the most moving scenes.

Embracing Lovers: Winter’s Warmest Promise

At the far end of the icefall, I unexpectedly came across a couple locked in an embrace. Amid the vast mountains and the frozen world, their silhouettes became the most beautiful scenery. They helped each other walk across the ice, every step cautious yet full of trust. Wasn’t this the perfect image of "holding your hand, growing old together"? On life’s slippery path, having someone willing to walk beside you—that is winter’s warmest promise.

Running Children: The Joy of Winter

On the ice, children are the happiest of all. They ignore the cold, running, slipping, and getting back up again. Every fall is accompanied by laughter, every rise by stubborn determination. This is what winter family activities in Beijing should look like—not hiding in a heated room, but bravely embracing the cold, leaving footprints of growth on the ice.

The Dream of Ice Climbing

In front of the largest icefall, I saw a dreamscape for ice climbing enthusiasts. That naturally formed ice wall, dozens of meters high, with thick and solid ice. Although I didn’t experience ice climbing myself, just imagining the sensation of scaling that ice wall was enough to make my heart race. Extreme sports have an inexplicable appeal—they let you feel the tension of life through challenge.

Chapter Four: Details of Ice – Wonders of a Microscopic World

If you think icefalls are only about grand, sweeping beauty, you would be wrong. Get closer, and you will discover a more exquisite microscopic world.

Ice Textures: Nature’s Signatures

Every piece of ice has its own unique texture. Some are like shark teeth—sharp and orderly. Others resemble overturned white waves, layered one upon another. Still others look like stalactites, growing slowly over long ages. These textures are the result of water flow speed, temperature changes, and air movement working together—each line is nature’s signature.

Ice Colors: Why is Ice Blue?

Ice isn’t just white. At Black Dragon Pool, you can see pale blue ice, transparent ice, and even ice with a hint of yellow. These colors come from the interaction between light and ice crystals. Pale blue ice is usually thicker and purer, because the ice crystals absorb red light from the spectrum, reflecting only blue light back. This phenomenon is a key feature of natural ice color science.

Ice and Plants: The Last Value of Life

Most astonishing of all is the combination of ice with branches and withered grass. In winter, bare branches have already lost their vitality. But when ice covers them, they seem to be reborn. The ice grows along the grain of the wood, forming unique "ice branches." Some branches are even bent under the weight of the ice, yet they stubbornly hold on, showing the last value of life.

Chapter Five: Beyond the Icefall – Winter’s Gifts

The icefall at Black Dragon Pool is just one part of winter’s bounty. In this season, the entire valley performs a miracle of solidification.

Ice on Rocks: Artificial Meets Natural

On the rocky surfaces, you can see ice formed by artificially poured water. Though man-made in origin, nature’s sculpting has given them bizarre shapes. Some look like mushroom clouds, others like fragments after an explosion, and still others like miniature glaciers. This ice contrasts sharply with the black rocks, creating the most beautiful winter landscape.

Frozen Streams: Time Capsules

The streams in the valley are completely frozen. The ice is thick and smooth, and walking on it, you can hear the sound of water flowing beneath. Fallen leaves and withered grass are scattered on the ice surface, sealed in like specimens of time. This is a perfect spot for winter photography in Miyun.
