About the Ganja La Pass Trek
The Ganja La Pass Trek is an 11-14 day trek that covers the Langtang Valley and then crosses the 5122m (16,800 ft) Ganja La Pass before continuing on. The trek involves at least three nights of camping in a remote area with one of the tougher technical passes to cross.
While the Langtang Valley is known as a moderate trek crossing Ganja La Pass is known for being one of the toughest passes to cross in Nepal. However, the views from the pass are the best in Langtang.
Though a guide is not mandatory and many people trek Langtang without a guide I would strongly advise anyone considering the Ganja La Pass Trek to take a guide and porter. There's camping equipment needed. The pass itself is tough and there's even a ladder in place these days to get over one section.
Tent on the Ganja La High Camp
The highest pass is indeed the Ganga La Pass at 5122m. There's also Kyanjin Ri (4300m) and or Tserko Ri (4984m) to climb which adds to this treks challenging aspect.

Where is the Ganja La Pass Trek?
The
Ganja La Pass Trek takes place in the Langtang National Park located
north of Kathmandu in the Langtang region of Nepal's
central development region. After the pass you enter into
Helambu area.
In many ways its easier to think of the Ganja La
Pass Trek as the Langtang Valley trek plus a high pass
out of the valley into the Helambu area.
The Langtang area was severely damaged in the 2015 earthquake. Landslides continue to remain an issue during the monsoon season. You should be cautious and only attempt this trek in the peak season.
There are up to three days of camping on this trek so you should be prepared with proper equipment including tents, sleeping bags, cooking equipment, and food. A good trekking company will provide these. However, do not that in Nepal providing your own equipment will not lessen your costs as the guide will still add on a fee for their own camping equipment. It's better to just let them get everything.

Buses or jeeps will take you to the start of the trail in the village of Syabrubesi. The first part of the trek follows the Langtang Khola (river) with tea houses and lodges offering accommodation.
Later the Langtang Valley has steep mountainous valley walls. Up ahead are the large white mountain peaks that you will have to reach and indeed climb!
The camping days and the Ganja La Pass days are the hardest for most trekkers. Ganja La Pass is steep, with broken trails, high boulders and indeed rock faces to climb up. An experienced guide is highly advised as accidents have occurred here. Going slowly with experience by your side is the best way to make the most out of this trek.

How to arrange a trek to Ganja La Pass
Arranging a safe Ganja La Pass Trek
Finding an experienced guide who has crossed Ganja La Pass is important. Unfortunately in Nepal many guides and trekking agents will say they know the pass, but few will have crossed it. You will need due diligence to find a guide who has made this crossing for the sake of your safety.
Keep in mins Ganja La Pass is considered a remote trek. Also, guides in 2025 are less keen on going on these types of treks vs easier ones. If you are stuck you can try my Find a Nepal Trekking Guide Service.
Package treks & tours bought online
Package treks & tours to Langtang are very easy to find but add in Ganja La Pass and you are down to a handful. After a few trekking agents read this article, even more, will probably pop up online! Once again with online tours, you'll be at the mercy of the trekking agency to know if they have a guide who as actually done this trek or not.
Many online Ganja La Pass treks are sold with 14 or more days. Do read the itineraries carefully to be sure none are "extended just for profit". Package tours usually include a guide, food, accommodation, camping equipment, cooking equipment, and permits. Costs can be from USD $1400+
Pro's of a package tour to the Ganja La Pass Trek include that everything is done for you ahead of time.
Con's include paying a higher than average price. You will not get to meet your guide beforehand. And the biggest question of all is they have done the trek before or not. Many online prices have additional hidden costs for solo trekkers. Many will have hidden extras examples of these include guides transport fees, meals, your meals etc.
Package treks bought in Nepal
Those with a couple of days in Kathmandu can arrange a package trek to Ganja La Pass with a lot more ease. The downside will be trying to figure out if the guide knows the pass or not - mobile photos help but look out for those copied from the internet. Selfies help!

Likewise, be sure you are going at the right time of year and the trekking company tells you this. If they don't, walk away.
It's also important you make sure that both you and the trekking company
agree on what's included in the total
price. This should include your camping equipment, permits, bus fees, meals etc.
The Langtang side of the trek has accommodation but we
aware of trekking companies trying to make out you need to
pay extra due to the earthquake. Langtang village was
completely destroyed but the New Langtang is up and
running.
Pro's of a local package trek to Ganja La includes meeting your guide before your trek and getting to see your tents/equipment. Being able to customize your treks itinerary to your own needs. See costs for pricing but expect it to be lower than the online packages.
Con's include having to spend a day going between trekking companies and possibly even waiting to meet the experienced guide.

Hiring a local Ganja La Pass Guide yourself
There are many local guides that can take you on a Langtang Valley trek. However, do not listen to the bluster that they've crossed Ganja La Pass. There's a huge difference in difficulty between the two. You do not want to be crossing Ganja La pass without an experienced guide who has done it before.
You'll also need a porter to help with the tents, sleeping bags and cooking equipment. I get many trekkers saying they can carry their own gear but the reality is the gear is heavy and you'll need to carry supplies. Do not take Ganja La Pass lightly.
Pro's here include a more independent trek.
Con's include having to get your own permits, making sure the porter is good, interviewing guides, getting camping equipment and getting cooking equipment. If you've not trekked in Nepal before and are attempting Ganja La Pass then my advice is to hire a guide who will do all this for you.
If you are looking for a guide on the Ganja La Pass Trek I recommend you read my article on How to find a trekking guide in Nepal. However, do be aware that many agencies will simply say that they have an experienced guide for Ganja La but don't actually have one. Yes, they'll take this type of change.
