Tomorrow, Monday, January 19th, is a special day in the Himalayas. As the sun rises over the Langtang mountains, it brings with it the start of Sonam Lhosar 2026.
For the Tamang community, this isn’t just a change of date. It is the beginning of the Year of the Horse (Ta Lho). It is a time of new beginnings, loud drums, and families coming together. While the city of Kathmandu will have parades, the true spirit of this festival lives in the quiet, ancient villages north of the valley.
At Kathmandu Summit Adventure, we believe the best way to understand a culture is to walk through it. That is why we love the Tamang Heritage Trek. It is more than a trek; it is a chance to be part of the celebration.

Who Are the Tamang People? (The “Horse Warriors”)
To understand the festival, you first need to know the hosts. The Tamang people are one of the oldest communities in Nepal.
There is a powerful story hidden in their name. In their language, “Ta” means Horse and “Mang” means Warrior. Legends say their ancestors were the brave horse warriors of ancient Tibet who settled in these hills to guard the land.
This makes 2026-the Year of the Horse extra special. It feels like the year of the Tamang people themselves. Trekking the trail this year is a beautiful way to honor that history.

What is Sonam Lhosar?
You might wonder, “What does Sonam Lhosar actually mean?”
It is simple. “Lho” means Year, and “Sar” means New. But the word “Sonam” is about farming-it translates to “Agricultural Merit.”
Long ago, farmers celebrated this festival to thank the earth and the gods after the winter harvest. It was a way to rest and pray for good crops in the coming spring.
If you visit a Tamang home during Lhosar, you will see:
- Clean Homes: Families clean every corner to sweep away the bad luck of the past year.
- Colorful Flags: New prayer flags are hung to carry wishes on the wind.
- Tasty Food: You will likely be offered Khapsey (a sweet, deep-fried pastry) and Babar (rice bread). These foods were made to give farmers energy in the cold.
- Music: The air fills with the beat of the Damphu-a small hand drum. This rhythm guides the Tamang Selo dance, where everyone, young and old, joins in.
The Tamang Heritage Trail: Culture Over Climbing
Most people come to Nepal for the high mountains. But the Tamang Heritage Trail offers something different: deep culture.
Located in the Langtang region, this trek doesn’t force you to climb extremely high altitudes. It stays below 4,000 meters. This makes it a moderate trek, perfect for anyone who wants to experience the mountains without the extreme struggle of high-altitude climbing.
The Villages You Will Visit
Our 14-day itinerary takes you to the most beautiful “living museums” of the region:
1. Gatlang (The Black Village) On Day 4, we reach Gatlang. It is famous for its rows of stone houses topped with black wood roofs. Walking here feels like stepping back in time. During Lhosar, the village square comes alive with dancers in traditional dress.
2. Tatopani (Views and History) A short trek takes us to Tatopani. The name means “Hot Water.” While the old hot springs have changed since the earthquake, the village remains a symbol of strength. The views of the Ganesh Himal mountains from here are simply breathtaking.
3. Thuman and Briddim These villages are special because they are close to the border. In Thuman, you can feel the shamanic traditions. In Briddim, the houses look just like those in Tibet. It is a rare chance to see how cultures blend together in the mountains.
Why Choose a Homestay?
The best part of this trek is where you sleep. This is known as homestay trekking in Nepal.
Instead of a busy hotel, you stay in a local family’s home. You eat in their kitchen, by the warm fire. You are treated as a guest, not a tourist.
Imagine sitting by the hearth, sipping warm butter tea, and listening to your host tell stories about the Year of the Horse. These are the moments you will remember forever-far more than just a mountain view.
When Should You Go?
While the Lhosar festival is happening right now, the trail is beautiful all year round.
- Spring (March to May): The forests turn red and pink with rhododendron flowers.
- Autumn (September to November): The sky is clear blue, giving you the sharpest views of the mountains.
