What can make the Langtang Gosaikunda with Surya Kunda Pass Trek difficult?

The Langtang Gosaikunda with Surya Kunda Pass Trek is considered a moderately difficult to hard trek due to its different challenging factors, such as altitude, trail condition, weather, etc. These different challenging factors are listed and explained below:

Road Travel During Langtang Gosaikunda with Surya Kunda Pass Trek

Before starting the trek, you need to travel by vehicle to Syabrubesi, which is located in the Rasuwa district of Nepal, the starting point of the trek. The drive from Kathmandu to Syabrubesi is long, winding, and bumpy, taking 6-7 hours. The drive can be tiring, but it offers fascinating views of rural Nepal life and stunning valley views.

Trail Condition of Langtang Gosaikunda with Surya Kunda Pass Trekking

In this region, the trail itself is demanding, with steep and rocky paths. During the winter, trails might get slippery making the path more challenging. You will need good stamina for several days as you will be walking 5-7 hours daily. However, with prior physical training or with proper guidance, you can complete this trek and enjoy the beauty of Surya Kunda Pass trek.

Altitude and Its Consequences


On this trek you will reach to the the highest altitudes, Tsergo Ri (4,985 m) and Surya Kunda Pass (4,610 meters). At this point air gets thinner with less oxygen, which can lead to Acute Mountain Sickness (AMS), with symptoms like headaches, nausea, dizziness, and severe fatigue. So, your body needs extra rest time for proper acclimatization so that it gets slowly used to the height.

Longest Day Walk of Surya Kunda pass trekking

One of the  longest day walks in this trek is from Kyanjin Gompa to Tserko Ri and back, which covers the total distance of 15-17 km with 8-9 hours of walking in a single day. This day also involves the significant elevation gain from 3,870 m to 4,985 m, making it the highest point of the trek. Upon reaching Tserko Ri, you will be surrounded by majestic snow-capped mountains and glacial lakes.

Weather and Temperature

The weather in the high Himalayas can change rapidly and sometimes gets extreme. During the nighttime and early morning, temperatures can get below the freezing point, especially near the pass, above tree line areas, and at high-altitude lodges. Proper gear, including layered clothing and a good sleeping bag, is really important for the safety.

Biggest climb of the day during Langtang Suryakunda Pass trekking.

The biggest and most challenging climb occurs when climbing from Kyanjin Gompa to the Tsergo Ri, which is at 4,985 meters, making it the steepest climb in the entire journey. This day involves continuous uphill walking, gaining an altitude of 1130 m in a single day over rough and exposed terrain. Due to high altitude, there is a risk of fatigue and altitude-related issues, so proper acclimatization is very important.

Icy Trail

The trail is usually good and clear, but if there is snowfall, the trail might get icy and slippery on this Himalayan trekking route, especially near Tserko Ri, Gosaikunda and Surya Kunda Pass. You will need good grips in your boots or crampons and walk carefully in such conditions. With the help of our experienced guide, you can safely cross the path and enjoy the authentic Himalayan experience.

Hot showers are available in most of the teahouses, but in the more remote areas electric charging stations are available only in the dining room. Also, attached bathrooms are not available in Lama, Gosaikunda and Ghopte hotels.

Electricity availability

Electricity is generally available in most of the tea houses but not reliable in remote areas. A charging station is available in the dining room of each hotel. Since the local power plant is not reliable, we highly recommend carrying a power bank with an extra battery, especially in high-altitude villages.

Breakfast includes different choices such as toast or Tibetan bread with eggs, Hash Brown Potatoes, Oat Porridge with Jam or Honey, Served with Tea or coffee.

Medical Services available en route to Lantang Surya Kunda Pass Trekking.

You will find basic medical support in Syabrubesi only, but if advanced or serious treatment is required, trekkers will be returned to Kathmandu. This shows it’s important for trekkers to monitor their health carefully and carry a basic medical kit.

Evacuation and Rescue

If there are any minor emergencies, trekkers can be evacuated by horse from certain parts of the trail, but if there are any serious cases, a helicopter is the best option,as it is the safest and fastest means of transportation at higher altitudes. Since helicopter rescue costs are very high, having trekking insurance is highly recommended.
