First-time snow travellers should prepare for more than just low temperatures. In Arunachal Pradesh, snow, ice, altitude and rapidly changing mountain weather can all affect a winter trip, particularly around Sela, Tawang and higher sightseeing routes.
Wear clothing in layers and keep your head, hands and feet protected from prolonged cold. Water-resistant footwear with good grip is especially useful because packed snow and ice can be slippery. Change damp socks or clothing rather than remaining outside in wet layers.
Walk slowly on snowy or icy surfaces and avoid steep roadside slopes, frozen lakes and unfamiliar snow-covered ground. Snow can conceal rocks, holes and uneven surfaces, while the thickness of lake ice cannot be judged safely by appearance.
Altitude is another concern for beginners. Keep physical activity gentle at high elevations and pay attention to headache, dizziness, nausea, unusual tiredness or breathlessness. If symptoms become severe or worsen, descend to a lower elevation and seek medical assistance rather than continuing the excursion.
Road conditions should be checked before every high-altitude journey. Snowfall, black ice, fog or poor visibility can temporarily affect access even when the route was open the previous day. Travel during daylight where possible and use a driver experienced with local winter roads.
Carry water, snacks, personal medicines, a small first-aid kit, identification, permits, some cash and a charged phone or power bank. Keep an extra warm layer inside the vehicle in case a journey takes longer than expected.
Most importantly, keep the itinerary flexible. Do not continue towards a snow viewpoint when local authorities, drivers or weather conditions indicate that the route is unsafe. Missing one excursion is preferable to taking unnecessary risks in unfamiliar winter terrain.
