A snowfall trip in Sikkim requires clothing for freezing temperatures, wind and wet conditions, particularly when visiting high-altitude areas. Dress in layers rather than relying on one heavy jacket, as this makes it easier to adjust when moving between warmer towns, vehicles and exposed mountain locations.
Pack thermal base layers, a fleece or warm mid-layer, an insulated outer jacket, gloves, warm socks and a cap that covers the ears. Waterproof or water-resistant footwear with good grip is particularly useful because packed snow, slush and ice can make walking surfaces slippery.
Sunglasses and sunscreen are useful at snowy locations because sunlight reflected from snow can be intense. Also carry water, light snacks, essential medicines, identification, required permit documents, a charged phone and a power bank for longer mountain excursions.
High altitude requires as much attention as the cold. Places such as Tsomgo Lake, Nathula Pass and higher parts of North Sikkim can cause headache, dizziness, nausea or unusual breathlessness in some visitors. Keep physical activity gentle, and move to a lower elevation and seek appropriate assistance if symptoms become severe or continue to worsen.
On snow-covered roads, follow local access restrictions and avoid pressuring a driver to continue when conditions are unsafe. Fresh snowfall can hide ice and reduce visibility, while an open road can still be difficult to travel.
Avoid walking onto frozen lakes or climbing steep, untreated snow slopes simply for photographs. Keep high-altitude sightseeing flexible, check current weather and road conditions before departure, and carry enough warm clothing to remain comfortable if the journey takes longer than planned.
