Chadar Trek Trail

A winter-only ice trek along the frozen Zanskar River in remote Zanskar, Ladakh, India.

Time to Hike: 9 days - roughly 62 km on the ice; typical programs allow 8 to 10 days including approach and exit days.

Best Time to Go: Mid winter - mainly January and February when the river most consistently freezes; freeze and break-up vary year to year.

Getting there: Fly into Leh and then arrange winter road transport to the Zanskar gorge and the trailhead; weather and snow can delay road travel so allow flexibility.

Costs: Expect to pay several hundred US dollars for an organized, guided trip that supplies tents, fuel and cooks; there are no huts on the route so budget for rental gear and local transport. Check local authorities about required permits for travel in Ladakh.

Difficulty: Walking is on frozen, often uneven river ice with occasional snow sections, narrow gorges and rockfall hazards; typical altitudes are around 3,000 to 3,500 m. Extreme cold, thin ice and avalanche risk make it a demanding winter expedition.

The route sticks to the frozen Zanskar River as it winds through a dramatic, narrow gorge cut into layered rock. Hikers pass limestone cliffs, icefalls and scattered winter settlements, with the river ice forming a walking surface that changes daily with temperature and snow.

There are no mountain huts on the Chadar; nights are in expedition tents or sometimes in community guesthouses at the ends of the walk. What makes the trek notable is the singular experience of walking a river in winter, combined with close encounters of local winter life and a landscape few see outside a short deep-freeze window.

The nearest airport and service hub is Leh, which has regular flights from major Indian cities in the warmer months; winter schedules can be limited so check flights early. From Leh you must arrange winter road transfers or an operator to reach the Zanskar gorge and the river trailhead; travel times depend on snow and road clearance.

Most groups approach the frozen river from higher upstream points and walk downstream toward the Indus valley for logistical simplicity and safer exit options. Book transfers with operators experienced in winter mountain travel who know local road and weather patterns.

The walkable season is short - mainly January and February when sustained ice forms. Some seasons the river freezes later or breaks up earlier, so flexible scheduling is essential.

There are no huts to reserve; you should book a licensed operator who handles winter camping, fuel and permits. Expect very short daylight hours, extreme cold and the potential for thin ice or avalanches; follow guides closely and carry appropriate cold-weather and safety equipment.
