    How To Reach Sankri

    Early morning board your vehicles to take one of the very picturesque Himalayan drive following the Yamuna and the Tons river. You may stop by at Mussurie for having a quick breakfast and at Kempty falls enroute to start with the fun game right away.

    After a drive of some 7 hours, you will arrive in Sankri by evening. On reaching, one of our representative will greet you and guide you to your hotel room. Once you are settled and freshened up, we meet over for evening Tea and Snacks. That's where we get introduced with the Team, issue you personal equipments for extra hygiene and safety, and share latest updates for the Har Ki Dun trek in short. 

    Our dinner gets ready by that time, and we get ready for a savoury dinner cooked by our expert cook hired locally.

    Today after breakfast, we start our journey towards Taluka. It will be done on an offload camper. The road is very thrilling and beautiful at the same time. One side of the road is completely exposed to abyss while the other side keep crossing rock fall, landslide zones and small streams which become very difficult at times.

    After we reach Taluka, we meet the remaining member of our support crew, mainly the horseman who loads the trek equipment and ration on the mules, while we start the trek with the guide. Its a gentle walk following the gushing Har Ki Dun river.

The trek is steep in a few sections today. The Campsite of Kalkati Dhar is very beautiful with the Har Ki Dun peak and the Hata Peak hovering over the beautiful meadow of Kalkati Dhar surrounded by dense jungle all around. The river is down below and can only be heard from here. From the camp of Halche, we could also see the twin peaks of Bandarpoonch.

After spending some time here, we move forward to yet another beautiful campsite of Maninda Tal.

    Todays day doubles up as a reserved day incase weather plays foul or due to any other unplanned event. We can skip over this day. It is here to help us acclimatize well and we utilize it well to explore the Jaundhar Glacier region in the morning. You will be taken aback by the sheer beauty of the landscape here. We return before lunch, and a little rest after lunch, we shift our camp ti Rataa Tho sleeping little beyond 4000 meters today. Its the most important day for the success of this trek.

    From here the trek changes its feel and starts to offer its challenges firstly in getting steeper, and the terain changes to that of a typical glacial moraine filled with boulders and scree zones. An effort of some 4 hours brings us to the camp site of Sawan Bedha

    4000 - Rataa Tho
    Day 6
    4540 - Saun Bera

    As a penultimate day before the Pass Crossing day, this day serves as the last chocolate bar before hitting the trail leading to the summit of the pass. A short day at an altitude above 4500 meters. It makes sense to make it shorter. The terrain gives no relief though.

    Day 7
    4540 - Saun Bera
    Day 7
    4870 - Lamjunga


    4 - 5hrs.

  • From Lamjunga (4870m ) To Bonga (4480m ), Via - Borasu Pass (5450m ) - 8-9 Hrs.

    Overnight In: Bonga (4480m )
    Accommodation: Camping
    Meals Included: Morning Tea, Breakfast, Lunch, Evening Tea Snacks, Soup, Dinner, Dessert, Hot Drinks

    The toughest day of the trek. An effort of some 3 hours over steep terrain of snow over scree zone takes us to the summit of the pass. From here, you can see back your trail and start imagining your past days and the effort you put to reach till here. However, things are not complete yet. There is a tactful descend to negotiate which still maintains the difficulty of the trek. A campsite exists just after descending down the pass, but it is advisable to reach the welcoming meadows of Bonga and rest out the night.

    Day 8
    4870 - Lamjunga
    Day 8
    5450 - Borasu Pass
