Early morning drive from Sankri to Taluka in a Taxi. Taluka is the starting point of our Borasu Pass Trek. After Breakfast in Taluka, we will Start trekking with packed lunch to Seema (2260m) on an even surface through thick forests of chestnuts, walnuts, willows, chinars and a variety of conifer trees. The trail is adorned with waterfalls. You could either opt for the steep climb of Dhaatmeer village or just trek along the Karmanasha stream. Both the routes meet at Gangaar village. Reach Seema Camps by late afternoon. Overnight stay in tents.

The trail from Seema initially continues on the true left of the valley, goes past fields followed by crossing a hanging bridge over river Rupin, to the true right of the valley. The trail now ascends, go past through fields and pastures with huts. The coniferous flora on the opposite side of the valley is awesome and much adorable. The trail climbs to the ridge locally named as Kalkatti Dhar, from where the trail traverses to give you an awesome view of Har Ki Dun. From here initially, the trail climbs gradually and later gets steep in times go past through beautiful meadows to the campsite at Har Ki Dun. The campsite is by the small stream, with peaks of Har Ki Dun and Swargarohini towering above. Overnight in the tents.

Cross the wooden bridge near Har ki Dun Forest Rest House and take the mud trail towards right leading to a lush green valley. Hata peak (just behind forest rest house ) and Swargarohini Peak are prominently seen from here. Continue on the trail which then passes through huge boulders. 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. The valley gets narrower with huge rocks and boulders all around. Following this you will come across a green meadow and a rocky trail with an ascent that takes you to the campsite of Ratha Tho. We camp here for the night.

Today is going to be a short trek. The trail takes you through boulders and waters of Borasu Glacier with mesmerizing views of the Borasu Pass and peaks. Crossing streams the trail will take you to a flat meadow thus alternating between meadows and rocky terrain. We will continue walking over scree and thin ice with snow patches between rocky landscapes. Climbing a snowfield following a trek for about 30 mins will take you to the campsite of Saunbhera. This is a huge meadow with streams that flow down to form Marinda Tal. You get to see the Borasu Pass and other splendid peaks from this campsite. We camp here for the night. Spend the rest of the day resting and exploring the surroundings. Overnight in tents.

Today’s trek will be a short one as well. Leaving behind Saunbhera the trail takes you over scree with huge boulders and loose rocks. 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. Following a climb over a steep ridge, you will reach the Upper Lamjunga campsite where we will camp for the night. The campsite is between the Borasu Pass and the Borasu Glacier. Overnight in tents.

We start as early as possible with the first rays of sun shining on the surrounding peaks. Looking behind en route to the pass gives you beautiful views of the Borasu Glacier, Saunbhera campsite, green valleys and zig-zag streams. 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. After ascending a steep scree slope you will have to walk over a ridge to reach the campsite of Bonga. Overnight in tents.

Today’s trek is a long one of 14km that takes you on an initial trail of loose scree and rocks parallel to a stream with snow covered slopes on the other side of the stream. After a couple of hours of gradual descend the trail flattens taking you to a green meadow. For the next couple of hours the trail alternates between a flat terrain and boulders. After a few hours the trail takes you through a dense forest and further down to a meadow before reaching the ITBP camp. This is one of the best walks of this trek. Walk is under the shade with a gentle gradient with a flat trail for the next 3 hours taking you to Chitkul. Overnight in Chitkul Village. Borasu Pass Trek ends here. You may plan your return on the next day.
