A snowfall trip in Arunachal Pradesh requires clothing that protects against cold, wind and wet conditions. Pack thermal base layers, a warm mid-layer, an insulated jacket, waterproof or water-resistant outerwear, gloves, a warm cap and thick socks.
Footwear is especially important after fresh snowfall. Choose waterproof shoes or boots with good traction to reduce the risk of slipping on packed snow and ice. Carry spare socks and, if possible, an extra pair of gloves in case your first set becomes damp.
Protect your eyes and exposed skin with sunglasses, sunscreen and lip balm. Keep water, snacks, personal medicines, a basic first-aid kit, identification, required permits and a charged power bank in an easily accessible daypack.
After fresh snow, walk slowly and stay on safe, accessible surfaces. Avoid steep snow-covered slopes, roadside edges and frozen lakes. Never walk onto a frozen lake simply because the surface appears solid, as ice thickness can vary considerably.
Check the latest weather and road conditions before travelling to high-altitude locations such as Sela, Bum La, Mayodia or the areas around Tawang. Fresh snowfall can create beautiful scenery but may also bring poor visibility, slippery roads and temporary access restrictions.
Altitude adds another safety consideration at destinations such as Sela and Bum La. Keep physical activity gentle and watch for headache, dizziness, nausea, unusual tiredness or breathlessness. If symptoms become severe or worsen, descend to a lower elevation and seek medical assistance.
Keep extra warm clothing and essential supplies inside the vehicle rather than buried in luggage. Allow additional travel time and keep the itinerary flexible, since snowfall can delay road journeys or make planned excursions temporarily unavailable.
