Snow in both Arunachal Pradesh and Sikkim is most dependable at higher elevations. Arunachal Pradesh has its main snow belt around Tawang and the surrounding passes, while Sikkim's popular snow experiences are concentrated around high-altitude lakes, passes and northern mountain areas.
Snowy Places in Arunachal Pradesh
Sela Pass is one of the most prominent winter snow locations in Arunachal Pradesh. Its high elevation allows snow to accumulate around the mountain slopes and Sela Lake, although heavy snowfall can restrict access to the old pass road and viewpoints.
Tawang can receive snowfall during winter and provides a convenient base for exploring nearby snow areas. Bum La Pass usually has more severe winter conditions because of its higher elevation, but visiting requires additional permission and depends on road clearance and local restrictions.
PT Tso and Sangetsar Lake can also be surrounded by snow during colder periods, subject to road access. Elsewhere in the state, Mayodia Pass can receive winter snow, while Mechuka may have snow in the valley during some weather spells and more consistent snowy views on the surrounding mountains.
Snowy Places in Sikkim
Tsomgo Lake is one of the most accessible high-altitude snow destinations from Gangtok during winter when the road is open. Nearby Nathula Pass also experiences severe cold and substantial winter snow, although permits, weather and road conditions determine whether visitors can reach it.
North Sikkim has extensive high-altitude winter landscapes. Areas around Lachung and Yumthang can experience snow, while higher routes towards Zero Point generally have stronger snow conditions. Access can change quickly after heavy snowfall, and some northern routes may become restricted during severe winter weather.
For either state, seeing accumulated snow is generally easier than timing a fresh snowfall. Travellers should keep dates flexible and check current road conditions because the same snowfall that improves the scenery can temporarily prevent access to the highest locations.
