December is cold, clear and quiet. The skies are often sharp, the trails are emptier than in October, and the lower valleys are comfortable in the daytime. The catch is the cold at night and the snow on high passes. Here is how to choose a trek that suits the month.

What December is like
Daytime walking at lower altitude is pleasant, often in sunshine. Mornings and nights are cold, and the higher you sleep the colder it gets. High passes can be blocked by snow, and a weather day can cost you the crossing.
Treks we run in winter
Two of our routes are listed for winter, December to February. The Langtang Valley Trek goes up to Kyanjin Gompa at 3,830 m, with an optional climb to Kyanjin Ri, and starts with a five to six hour bus ride from Kathmandu. The Tamang Heritage Trek tops out at 3,165 m and uses village homestays. Both start from Kathmandu by road, with no flight.
Treks to skip in December
We schedule the Annapurna Circuit and the Manaslu Circuit for autumn and spring only. Their passes, Thorong La at 5,416 m and Larkya La at 5,106 m, are far more likely to be snowed in or dangerously cold in midwinter. Ask us before you plan a high pass in December.
What to bring
Layers matter more than any one big jacket. A down jacket and sleeping bag are on loan on our treks, but bring warm base layers, a hat, gloves and good boots. See our packing list and add a second warm layer for winter. Hot showers are an extra charge on most treks, and lodges are rarely heated, so expect to dress for dinner.
Is December the right month for you?
If you want solitude, clear views and you are comfortable with cold, yes. If you are doing your first trek and dislike cold, consider October, November or March. Our best time to trek Everest Base Camp page covers the seasons in more detail, and you can ask us about your dates.
