Walking on ice that may or may not hold your weight, sleeping in caves at -25°C, and discovering that the Chadar Trek is not an adventure sport — it is a pilgrimage along a river that has been a highway for centuries.
The Zanskar River freezes in winter. Not just a thin crust of ice, but a solid sheet several feet thick that transforms the river into a highway. For centuries, this frozen river — the Chadar — has been the only connection between the isolated Zanskar Valley and the outside world during the winter months. When the snow blocks the mountain passes, the river becomes the path.
I had heard about the Chadar Trek for years — one of the most extreme treks in the world, they said. Walk on a frozen river through a gorge where the cliffs rise a thousand feet straight up, where the temperature drops to -30°C, where the ice can give way without warning and plunge you into water that will kill you in minutes.
But when I finally stood at the trailhead in Chilling, looking down at the frozen river, I realized that calling this a "trek" was misleading. This was not recreation. This was a journey that people had been making for centuries out of necessity, and doing it as a tourist felt like something that required respect and humility, not just physical preparation.
My guide was Tashi, a Zanskari who had been walking the Chadar since he was a child. His father had walked it, and his grandfather before him. For them, it was not an adventure — it was simply how you got to Leh in winter to trade, to visit family, to access medical care.
"The river is different every year," Tashi told me as we descended to the ice. "Sometimes it is wide and easy. Sometimes it is narrow and dangerous. You must listen to it. The ice will tell you if it is safe."
I did not understand what he meant until we started walking. The ice was not uniform — it changed from hour to hour, from bend to bend. In some places, it was thick and solid, blue-white and reassuring. In others, it was thin, dark, almost black, and you could hear the water rushing underneath. Tashi would stop at these sections, kneel down, press his ear to the ice, then choose a path based on what he heard.
"The black ice is singing," he explained. "It is telling us where the current is strong, where the water is shallow, where we can cross."
The first day was terrifying. Every step was a negotiation with fear — is this ice thick enough? Will it hold? What happens if it doesn't? I walked with my heart in my throat, eyes fixed on the ground, barely noticing the spectacular gorge around me.
But slowly, over days, I learned to read the ice the way Tashi did. I learned that the white ice is air bubbles, weaker than the clear blue ice. I learned that cracks running parallel to the river are normal, but cracks running across are danger. I learned that the ice sings differently in the morning than in the evening, that temperature changes everything, that the river is a living thing that must be respected.
We walked for eight days, covering roughly 70 kilometers. Each night, we camped in caves along the gorge — natural shelters that have been used by travelers for centuries. Tashi knew them all by name, knew which ones were dry, which had the best views of the stars, which were close to springs where we could get water.
The cold was relentless. -25°C at night, maybe -15°C during the day if the sun managed to penetrate the gorge. Everything froze — our water bottles, our boots, the condensation from our breath on our sleeping bags. Getting up in the morning required a psychological effort that was harder than any physical challenge. Putting on frozen boots, packing frozen gear, stepping out into air that hurt to breathe.
But the beauty was overwhelming. The gorge in winter is a sculpture of ice and stone, with frozen waterfalls hanging like chandeliers from the cliffs, with the river winding through in shades of blue and white that no photograph can capture. The silence was absolute — no birds, no insects, no wind in trees because there were no trees. Just the occasional crack of the ice shifting, a sound like thunder that reminded us we were walking on a river that was still flowing beneath its frozen skin.
We met other travelers on the Chadar — Zanskari families walking to Leh, monks returning from pilgrimage, porters carrying supplies. Each encounter was a moment of connection in the vast emptiness. We shared tea, stories, the warmth of human presence. Tashi knew many of them by name, knew their families, their histories. The Chadar was not wilderness to him. It was home, community, a place of relationship.
On the fifth day, we reached Nyerak, a village that exists only because of the river. In summer, it is accessible by road. In winter, it is an island, completely cut off except by the Chadar. The villagers welcomed us with butter tea and stories, grateful for the contact with the outside world that we represented.
An old woman named Dolma invited me into her home, a traditional Zanskari house with thick mud walls and a central hearth that never went out. She made me tea and told me about her life — sixty years of winters on the Chadar, of walking to Leh and back, of losing friends to the river, of raising children in isolation, of watching the world change while Zanskar remained the same.
"The young people don't want to walk the Chadar anymore," she said, her eyes reflecting the firelight. "They want roads, vehicles, easy life. But the Chadar teaches things that roads cannot. It teaches you what you are capable of. It teaches you to respect nature. It teaches you that some journeys cannot be rushed."
I thought about her words as we walked the final days to Padum, the administrative center of Zanskar. The Chadar had changed me in ways I was only beginning to understand. I had come seeking adventure, a story to tell, photographs to share. I was leaving with something quieter but more profound — an understanding of what it means to move through a landscape with full attention, to accept what the environment offers rather than demanding what I want, to find beauty in hardship and community in isolation.
The last morning, we walked on ice so clear we could see the riverbed below, stones and sand frozen in time. The sun rose over the gorge, turning the ice to gold, and for a moment I felt what Tashi must feel — not fear, not conquest, but relationship. The river was not an obstacle to overcome. It was a teacher, a companion, a path that had been laid down by centuries of travelers before me.
I left Zanskar by road, the new highway that is slowly making the Chadar obsolete. Tashi stayed, walking back the way we had come, returning to his village. We embraced at the parting, two people from different worlds who had shared something ancient and universal — the simple act of putting one foot in front of the other, day after day, trusting the ice to hold, trusting the journey to transform.
The Chadar is melting earlier each year now, climate change shortening the window when it is passable. Some years, it does not freeze solid at all. The Zanskari way of life is changing, adapting, perhaps disappearing. I am grateful I walked it when I did, not just for the adventure, but for the glimpse it gave me into a world where rivers are highways and ice is a gift, where the hardest journeys create the deepest connections, and where the frozen heart of winter can teach us how to truly live.
