Seasons of Upper Mustang Trek
Spring Season (March to May) – The Best Time for a Colorful Trek
Among the most popular and satisfying times to visit Upper Mustang is spring. Daytime temperatures are 10°C to 20°C (50°F to 68°F), and the nights are rather cooler. Mostly clear skies allow one to see unimpeded the rugged landscape and snow-capped mountains behind.

The Tiji Festival, celebrated in May, is among the major attractions of spring mountain climbing. Vivid mask dances, religious ceremonies, and centuries-old customs depicting the triumph of good over evil are all part of this three-day spiritual festival in Lo Manthang. Trekking during this period enables you to experience the vibrant Buddhist culture of the area and observe the magnificent performances of the festival.

Out of all seasons of upper mustang, spring highlights the beauty of Upper Mustang as the desolate terrain contrasts with blossoming wildflowers and fresh vegetation in the lower Mustang area. For photographers and nature enthusiasts to preserve Mustang’s amazing beauty, this is the ideal moment.
Summer/Monsoon Season (June to August) – A Rain-Free Monsoon Trek
Upper Mustang stays a great trekking possibility during the summer, in contrast with many other trekking destinations in Nepal where the monsoon season presents difficult trail conditions best tackled by experienced hikers. Since it is situated in the rain shadow of the Himalayas, the area gets little rain as contrasted to other parts of the country. Opposed to the usual desiccated ground, this gives summer a somewhat remarkable appeal for trekking since the trails are dry and the scenery assumes an unusual rich look.
Summer temperatures are milder around 5°C to 10°C (41°F to 50°F) while during the day they vary from 15°C to 25°C (59°F to 77°F). With fewer people present, the season offers a calmer trekking experience, perfect for those who seek solitude. Nevertheless, intermittent rain and overcast skies might affect mountain visibility, so hikers would have to be ready for the changing climate.

The summer season is a great time to explore the mystical sky caves, ancient monasteries, and the stunning walled city of Lo Manthang without the crowds. The lush greenery in the lower Mustang and the contrast of the red cliffs against the bright blue sky create a surreal trekking experience.
Autumn Season (September to November) – The Peak Trekking Season
Trekking in Upper Mustang is best in autumn since the season has clear skies, strong weather, and pleasant temperatures. With nights ranging from 0°C to 5°C (32°F to 41°F), daytime temperatures range from 10°C to 20°C (50°F to 68°F).
Autumn is perfect for photography and panoramic mountain views since the air is clear and visibility at its peak after the monsoon. With dry and hard trails, the trekking is ideal.

Fall brings local harvest celebrations and traditional rites in the villages to hikers. Most brilliant during this time of year, the cultural wealth of Upper Mustang gives hikers a genuine glimpse of the Himalayan way of life. Even so, one should reserve permits and lodging well ahead of time since fall is a very busy trekking time.
Winter Season (December to February) – A Trek for the Adventurous
Winter turns Upper Mustang into a peaceful, snow-covered scene, therefore providing a very different kind of trek. This is the least liked season, though, since it is very cold. A difficult hike results from night temperatures ranging from -10°C to -20°C (14°F to -4°F) and daytime ones from 5°C to 15°C (41°F to 59°F).

During winter, most Upper Mustang locals move to lower elevations and many tea houses stay shut. Winter trekking calls for great attention to planning since some high passes could be snow-covered and hard to cross. Notwithstanding the difficulties, the seclusion and natural beauty of a snow-covered Mustang draw hikers looking for a tranquil, reflective experience off the beaten path.
Winter travel to Upper Mustang could be fun if you have winter hiking experience and are ready for the cold. The ethereal scene formed by the icy waterfalls, snow-covered peaks, and clear skies provides a new viewpoint of this enigmatic area.
