When the tree line ends, you see a huge valley with a stream coming from Morinda Tal, a glacial lake formed by the streams coming from Borasu Glacier.

After an hour negotiating scree and moraines, you will reach the campsite of Upper Lamjung which is also the Borasu Pass Base Camp. The campsite area is quite limited but gives you the best view of the Borasu Pass. Lamjunga in local language means “Long Moustache” as the ridges below the pass give the appearance of a long moustache.

The trail takes you between boulders on a gradual snow slope that becomes steep eventually. The next 45 mins you will trek on a trail alternating between as steep slope and a plain snowfield. From this point onwards we might have to rope up or cut steps on the ice as the trail becomes steep with some loose rocks here and there. Three hours from the campsite is when you will reach the pass. The view from the pass is mindblowing with snow peaks, vertical snow slopes and the massive Zupica glacier which we will have to cross. We will have to rope up in order to descent from the pass to the other side. The trail takes you over the Zupica Glacier moraine followed by crossing of the Zupica Glacier over thin ice and crevasses for the next 30-45 mins.

Of course, this is a non-negotiable. Safety is embedded in our business and it’s something that we take very seriously in all our treks. It’s the primary reason we’re very popular in just a year.

• Personalized Service, Care, and Attention to Detail
For some organizations, this is, surprisingly, negotiable. But it isn’t for us. After safety, if we can do one thing right, every time, it’s to ensure that we sweat the small things.

• The Best Guides
If you are already trekking with us, then you’d be forgiven for thinking our guides are superhuman. It doesn’t mean feat to entertain, cook, guide and facilitate, but for our guides, they handle it with grace and all the while the attention is on you.

• The Best Itineraries
It takes a lot of refinement to make a perfect trek, from dawn to dusk there are a LOT of moving part and potential for things to go awry. From last one year, we’ve balanced on the tight rope of offering the right amount of activity, flexibility and trek time. Whilst utilizing the best lodgings in the most unique places.

• Value
We’re not in the business of making money and provide you nothing. Our treks aren’t expensive, they represent excellent value for money and for those seeking to maximize their time, there is no better way.

Our Expectations
It may come as a surprise, but the reality is that it is a two-way street (or trail), you are ultimately responsible for the nature of the experience that you have with us. And not only that, but you also have an influence on the experience of others’ in your small group.

• Attitude
This is your vacation, and the attitude that you bring will set the tone for your experience. We get that at times it’s difficult (we plan to challenge you) and we get that at times it’s a bit uncomfortable (this is not a cruise trip). All we ask you to keep an open mind, a big smile on your face and readiness for the unexpected.

• Physical preparedness
Our treks are designed for everyday people. You definitely don’t have to be an athlete, but to be fair for yourself and your group members, you do need to be ready. Worried about it? Do not stress it, our team is 100% dedicated to helping you pick the right trek, bring the right gear and be physically and mentally prepared.
