It Is Cold

This is the biggest disadvantage.

Kathmandu can have winter nights close to 3°C on average, while higher elevations can be much colder.

High-Altitude Trekking Gets Harder

Snow, ice, freezing nights, and shorter daylight make high-altitude trekking more demanding.

Some Mountain Services May Be Limited

In remote areas, some lodges and services may operate on a reduced basis during winter.

This is another reason to plan high-altitude treks carefully rather than assuming every tea house will operate normally.

Not Ideal for Everyone

If you dislike cold weather, December may not be your favorite time to visit Nepal.

What to Pack for Nepal in December

Your packing list should depend on your itinerary.

For Kathmandu, Pokhara, Chitwan, and other lower areas, you can keep things fairly simple.

Bring:

• Warm jacket
• Fleece or warm mid-layer
• Long-sleeve shirts
• Comfortable trousers
• Warm socks
• Hat or beanie
• Gloves
• Comfortable walking shoes
• Sunglasses
• Sunscreen
• Small daypack

For high-altitude trekking, you need a much more serious winter setup.

Consider:

• Thermal base layers
• Insulated jacket
• Waterproof outer layer
• Warm gloves
• Warm hat
• Quality trekking boots
• Warm sleeping bag
• Trekking poles
• Headlamp
• Sunglasses
• Sun protection

Some trekking equipment can be rented in Kathmandu or Pokhara, but do not rely on rentals without checking availability and condition before your trek.

The Nepal Tourism Board also recommends warm clothing during the October-March period.

Trekking Tips for December

Choose the Right Trek

Do not choose a December trek simply because it is popular in October.

Winter changes trail conditions.
