What is the route to Cho La like?
The journey to the summit starts from Chhanggu (Tsomgo Lake). The road is 22.4 km long and is characterized by its extreme technicality and verticality. To overcome the massive elevation gain, the track features an impressive 46 hairpin turns, snaking up the rugged Himalayan slopes.
Is the road to Cho La open to the public?
Due to its sensitive location on the international border and the heavy military presence, access is highly restricted. On the Indian side, a road leads to the summit, while on the Chinese side, recent infrastructure has brought roads very close to the top, though they may not fully connect over the crest. The pass is strictly impassable from October to June due to heavy snow and extreme winter conditions.
What are the driving conditions on the pass?
The road is purely a 4x4 track, unpaved and often covered in loose rocks and debris. The thin air at 4,593 meters significantly reduces engine power, and the steep gradients require a high-clearance vehicle with excellent traction. Driving here is reserved for military personnel and authorized travelers, as the route is one of the most demanding in the Sikkim region.
The scenic Chola Lake
Near the summit, travelers can find the Chola Lake, a high-altitude body of water that remains frozen for a large part of the year. The lake is surrounded by dramatic peaks and military outposts, offering a stark but beautiful landscape that few civilians ever get to witness in person.
Driving hazards in the Himalayas
The primary hazards include unpredictable weather, rockfalls, and extreme altitude. The road is narrow, and the 46 switchbacks require precise maneuvering. Because it is a military zone, there is no commercial infrastructure along the route, making self-sufficiency and high-quality off-road equipment absolute necessities.
