Thorong La and Larke La are the two names that trekkers most frequently mention when discussing the Nepalese mountain pass. Despite being different treks, both are demanding, cold, and high. The Thorong La lies on the Annapurna Circuit, while the Larke La lies on the Manaslu Circuit. In this blog we are explaining the difficulty and challenges of Thorong La Vs Larke La Pass journey.

It’s difficult to decide between Thorong La and Larke La. One is more distant, the other a little higher. While one still feels remote and unexplored, the other receives thousands of hikers each season. Strong lungs, effort, and a little bit of weather luck are required for both passes.

Overview of Thorong La Pass (5,416m)

Thorong La (5,416 meters) is like a jewel in the crown of the Annapurna Circuit trek. It is the circuit’s highest point and a must-visit in the area. The pass creates an almost unbelievable change in landscape by joining the dry Mustang landscapes with the lush green Manang valley.

Although the trail is well-established, crossing Thorong La is difficult.

You’ll come across tiny towns and tea houses. The places where you can relax, eat something hot, and get ready for the challenging ascent. Due to the high altitude, it is crucial to properly acclimatize yourself. The moment you finally reach the top is unbelievable.

Overview of Larke La Pass (5,160m)

The highest point of the Manaslu Circuit trek is Larke La Pass (5,106 meters). It’s lower than Thorong La, yet more challenging due to its rugged terrain and longer ascent. Against the dramatic backdrop of majestic peaks like Manaslu and Himlung Himal, the surrounding landscape feels unreal. Its raw and remote up there.

The Larke La Pass journey, while less busy than the Annapurna Circuit Trek, is filled with adventure. This sense of adventure is heightened by the lack of many amenities along the way, the rocky or cold trail, and the need for proper planning and a reliable advisor. Despite the challenges, every step is rewarding because of the expansive views that greet you at the summit.

Which Pass Poses More Risk of AMS?

Thorong La and Larke La both lie at high elevations. The risk of altitude sickness is high. Thorong La, at 5,416 meters, is slightly higher than Larke La’s 5,106 meters. One might believe that just having a higher altitude equals having a higher risk; however, it greatly depends on how you acclimatize and your speed of ascent.

Like the Annapurna Circuit, many trekkers on the Manaslu trek commonly spend a few extra nights in Samagaun or the Samdo. This allows their bodies to acclimatize before tackling Larke La. This acclimatization can mentally enhance many people’s experience of eventually crossing Larke La at a higher altitude. However, if you don’t take the time to acclimatize, headaches, nausea, and shortness of breath may occur.

Many trekkers have noted that even though Larke La can feel less complicated than Thorong La. They found Larke la more challenging due to the number of hours of a persistent uphill climb in thinner air.

So, which one is riskier? While the elevation of Thorong La generates additional concern regarding altitude sickness, it’s important to remember that many trekkers find Larke La equally challenging due to the long approach with less chance for rest. No matter the route, trekking at this altitude in Nepal requires carefulness, an even pace, and listening to your body to avoid altitude sickness.

Trail Length and Walking Hours

When evaluating the Thorong La vs Larke La pass, both involve long days. But there is a different pacing in the journey. The Annapurna Circuit approaches the Thorong La trek with a steady succession of acclimating stops. So, most trekkers spend around 10–12 days on the overall circuit. The day you arrive to start the Thorong La trek is usually your hardest day of walking, likely 8-10 hours.

On the Manaslu circuit, the approach to the Larke La pass is more rugged and remote. The complete circuit trek is typically 12–14 days long. The final push to reach the pass is known to be one of the longest pass in Nepal. Trekkers should walk 8-10 hours on that day. Although the Larke La is at a lower altitude, it can sometimes feel a bit harder for daily effort.

Terrain and Trail Conditions: Rocky vs. Rugged

The Thorong La trail’s difficulty lies mainly in the steep climbing at high altitude. The trail is obvious and well-maintained, as it is part of the busy Annapurna Circuit, so navigation is not the issue. Snow can make it slippery. In general, the trail is easy.

In contrast, the Larke La trail has rougher terrain. The path is generally rocky and sometimes icy and feels more “wild” than the more tourist-friendly Annapurna Circuit Trek. Many trekkers consider it one of the most challenging trekking trails in Nepal due to the elevation. You need to be prepared for long, high elevations and uneven climbs.

Weather and Seasonal Challenges at Both Passes

The weather changes rapidly in the Himalayas. Both passes are famous for their weather pattern of sudden storms. The best time for Thorong La Pass is in the spring (March to May) and autumn (September to November).

The skies are clearer and the trail is less likely to be covered in snow. The best time for Larke La Pass is also in the spring and autumn; however, as the Manaslu region is more remote, bad weather feels more ominous. Snowstorms can block the route rapidly, and with no sunshine, icy trails can last longer.

It is brutally difficult to cross in winter; the lower trails are also particularly prone to landslides and leeches during the summer monsoon.

Accessibility: Which Pass is Easier to Reach?

Going to the Annapurna Circuit is easy. For Thorong La Pass, most trekkers either start from Besisahar, whose roads go part of the way up the valley now. You can access the trailheads with buses and jeeps that will get you closer to the actual trek point, or help cut the trek shorter.

Accessing the Manaslu Circuit and reaching the Larke La Pass is more challenging. Usually, trek start from Soti Khola or Machha Khola. The journey from Kathmandu will be a long bus or jeep ride. Additionally, the Manaslu region is a restricted area. You need a special permit and a registered guide.

So, between the Annapurna vs. Manaslu, Thorong La is easier to access.

Accommodation and Teahouse Facilities

A significant distinction between the two treks is in comfort. In the Annapurna circuit, there are numerous well maintained tea houses with a range of menus and often Wi-Fi or hot showers. Annapurna region is more like a cultural and social journey as well as a mountain trek.

In the Manaslu circuit, tea houses are more limited and simpler in their type. Rooms are basic, menus are limited, and heating is uncommon. The Manaslu region makes you feel like you’re in a remote corner of the Himalayas! For trekkers who enjoy adventure and simplicity, this is part of the attraction.

Remoteness and Rescue Options

On the Annapurna circuit Trek, rescue from Thorong La Pass is much easier to arrange, as it is a busier route and more frequent helicopter rescues take place. Trekking agencies and tea houses are used to dealing with emergencies.

While in the Manaslu Circuit Trek, rescue from Larke La Pass is more challenging to arrange. It is a less developed area, and stormy weather will delay helicopters even longer, in case of an emergency. Therefore, while it may feel like you’re on a more adventurous trek, it can seem riskier too.

If you are worried about the potential of a helicopter rescue in treks in Nepal, don’t worry as Annapurna is a much safer route compared to Manaslu.

Scenic Beauty: Landscapes and Mountain Views

Both passes are excellent in their own right. The mountain scenery from Thorong La includes awe-inspiring views of the Annapurna, Dhaulagiri, and the Mustang Valley.

The Larke La Himalayas view is much wilder, rivaled only by the massive peaks of Manaslu (8,163m), Himlung, and Cheo Himal. Since there are fewer trekkers, you can enjoy the silence and open views of Larke La without the crowds.

You will see the best views during your trekking journey in Nepal, simply because they feel untouched and raw.

Which Pass is Harder for Beginners vs. Experienced Trekkers?

If you are thinking of doing a beginner trek in Nepal, neither trek is actually easy! However, Thorong La is the more beginner-friendly option due to better infrastructure, more acclimatizing breaks, and easier access overall.

If you would like a more challenging trek in Nepal, Larke La is it! It has rough trails and involves long days, making it more difficult than Thorong La.

Your question is Thorong La vs Larke La pass. In that case, Thorong La is the safer choice for beginners, and Larke La is better for experienced trekkers looking for an another challenge.

Tips to Prepare for High-Altitude Pass Crossings

All high passes treks in Nepal will require proper preparation. Here are a few trekking tips as you venture into the Himalayas of Nepal that could make a significant impact on your experience:

Train yourself: Get out for some long hikes (with a backpack) to get into shape.
Acclimatization: Do not be in too much of a hurry; it is better to add rest day, especially in Manang on the Annapurna Circuit Trek and Samagaun on the Manaslu Circuit Trek.
Backpacking: Layer clothing, good boots, and trekking poles are some core essentials. Pack lighter, but don’t miss out on anything.
Hydrate, eat, hydrate: Eat around 4000-5000cal a day, and drink 4-5L water.
Know your limits: Learn the symptoms of altitude sickness and listen to your body.
