Lumba Sumba Pass Trek - 19 Days

The Lumba Sumba Pass trek was only opened in 2012 so it is a relatively unknown trek. The trek connects the Kanchenjunga region and Makalu region via the Lumba Sumba Pass, and runs through the Kanchenjunga Conservation Area and the Makalu Barun National Park in the eastern part of the country and can be done in one of two directions: starting in either Kanchenjunga or in Makalu. Highlights of this trek include the Lumba Sumba Peak (5,300m); spectacular Himalayan landscapes of the Makalu and Kanchenjunga ranges; different ethnic villages (Limbu, Sherpa, Rai, Gurung, Tamang); cultural heritage; endangered wild life such as the snow leopard and red panda; the base camps of Mount Kanchenjunga and Mount Makalu, and major river systems. With the huge variety of landscapes and natural beauty, and its sometimes harsh and less than good condition trails, it is no surprise that this is a strenuous trek, therefore it is recommended people tackling this trek have prior experience.

While the majority of the trek passes through scattered pockets of human habitation in the form of villages, monasteries, markets and schools, there are days when trekkers are completely alone in the wilderness, particularly on the most difficult day – when they cross through the Lumba Sumba Pass. In order to cross the pass, the day starts very early as after noon, due to weather conditions, it is difficult to cross.

During these days off the beaten track there has been sightings of snow leopards, which would certainly add a new excitement to the journey! After crossing the pass, while hiking through the Arun Valley, there is opportunity for bird watchers to spot several unique and rare species. This is the ideal trek to enjoy spectacular mountain views and learn something about village life in eastern Nepal, throwing in a cultural mix of chortens, temples, monasteries and prayer wheels.

Is it safe to drink the water in Lumba Sumba Pass Trek?

No. You cannot drink the water from the tap or streams in Lumba Sumba Pass Trek. Mineral water is not available on the trail. You can use a water purifier or SteriPen.

Am I likely to get altitude sickness on my trek?

Be aware. Elevation on this trek will exceed 3,500m. The possibilities of getting altitude sickness generally start at this elevation. But in order to avoid this, as much as possible, we have designed the itinerary in such a way that it will give you enough time to acclimatize.

Am I at risk and how can I avoid altitude sickness?

There is no knowing who will suffer from altitude sickness. It does not follow that the younger and fitter people will not get altitude sickness where the older and less fit will. It is not related to (general) fitness or age. Talk to your doctor at home. There are prescription medications which help avoid the onset of altitude sickness. But above all, go slowly, listen to your body, be aware of any changes, and listen to your guide if he feels you are showing symptoms (which you might not notice).

What happens if there is need for emergency evacuation while I am trekking?

We will collect your travel insurance policies and details before the trek so that in case of an emergency we can coordinate with your insurance company and the helicopter providers for evacuation.

What about simple medical treatment on the trek?

First aid. On every trek we will carry a first aid kit. We also recommend you carry your own. Here is a checklist recommended by Karen Anderson of things you should bring. Vaccinations are not compulsory in Nepal but to be on the safe side we recommend you comply, where possible, with this list provided by again by Karen Anderson (medical doctor in New Zealand and friend and client of Magical Nepal).

Do I need to buy travel insurance before I come to Nepal?

Yes. Magical Nepal only provides insurance for our own staff. We recommend you buy insurance in your country. Note: Insurance should cover you for the altitudes you are trekking at (not all do). We recommend World Nomads.

Will I need to bring my own sleeping bag or not?

Yes, bring your own or you can rent it or buy it in Kathmandu. Renting a sleeping bag in Kathmandu will cost you $1 or $2 per day. To buy a new sleeping bag in Kathmandu expect to pay around $150 to $200 for one of medium quality.

Will I need to use crampons on this trek?

Yes. It is an exploratory trek, and weather conditions can be unpredictable. We might need to use crampons.

What happens if I forget to bring something with me from home?

If you forget something it might be extremely hard to find here. Please check here for an exhaustive packing list for (general) trekking in Nepal. If you are not a frequent hiker, you can rent most of the trekking gear in Nepal when you arrive.

Will we be using tents and mattresses on the trek?

Yes. It is an exploratory trek, and weather conditions can be unpredictable. We might need to use crampons.

Where can I leave stuff in Kathmandu when I am trekking?

Anything you don’t want to take on the trek with you can be stored at your hotel or in our office. We suggest you ensure your bag is lockable.

Who will be my guide?

We use local guides. On each trek our guides have been to the relevant areas numerous times. All are experienced, knowledgeable, flexible and authorized licensed guides with the Government of Nepal.

Will I need a porter for my trek?

Preferable. If you use a porter it has double benefit: you can fully enjoy your trek without carrying a heavy bag, and its improves the income of the local community.

How much can a porter carry?

20kg. On average a porter can carry 22kg including their own backpack. So, they can carry up to 18kg of your gear and equipment. We provide backpacks for porters.

Are your staff insured in case of accidents etc.?

Yes. At Magical Nepal we make sure all our staff are well insured.

I hear incidents when porters do not have proper shoes etc. Is this true?

At Magical Nepal we ensure all our guides and porters have proper gear, are well equipped and protected. This is for their own well being and for the wellbeing of our clients.
