We start in the morning, after breakfast to trek towards Chirbasa (3600mt). From Gangotri, you may move along the beaten track towards Chirbasa, which is on the tree line. The entire trek till Chirbasa is along the roaring Bhagirathi River. We can have our pack lunch in Chirbasa. From Chirbasa, we trek further to Bhojwassa today. The trek is going to be moderate for the day. The terrain, after Chirbasa, becomes really desolate and barren. In fact, it has been referred to as Arctic Tundra by many trekkers. The entire trail passes through a dense forest till Bhojwassa. There is a small temple and a potential campsite near the river. A good place to camp for the day. Excellent sunset on Bhagirathi group of peaks to delight you in the evening.

Early in the Morning enjoy the panoramic view of Bhagirathi group of peaks. After breakfast trek to Gomukh (3890mt), the source of the Ganges. Gomukh is where the water of Ganga trickles down from the glaciers. The sages called it 'Gomukh' because, in the distant past, it probably appeared like a cow's mouth. Explore the area and trek to Tapovan, one of the finest high altitude alpine meadows in the area. The trek from Gomukh to Tapovan is ascent steep, and as we climb, the view of the surrounding peaks becomes clearer. Tapovan known for its beautiful meadows that encircle the base camp of the Shivling peak, Tapovan is a very pleasant surprised spot with a large meadow complete with bubbling streams, wildflowers, and campsites. Herds of Bharal (blue mountain goats) are a common sight from here on mountain ridges. On the far side of the glacier the Bhagirathi I, II, III (6454mt), provide an equally impressive backdrop. It is also the little wonder where Sadhus and saints choose this spot for extended meditation during the long summer month. Arrive Tapovan and camp. Dinner and overnight stay in camp.

On this day we head to Nandanvan via Gomukh glacier. The route from Tapovan leads from the upper section of the meadow till down and onto the glacier. From Gomukh turn towards Nandanvan (4340m) and steering on right one will be on top of the Gangotri glacier. The glacier runs between two ranges and the landslides make a layer of rocky moraine on the ice which makes the walking easier. The glacier walk is very slippery and a slight lack of concentration would be dangerous. Huge crevasses gaped here and there. After a walking, for about a kilometer there is a vertical ascent. Big rocks en route offer grips and footholds but many of them are deceptive too. Dinner and overnight stay in tents.

Morning trek along with Chaturangi Glacier to reach Vasuki Tal, a beautiful base for Mt Satopanth and Mt Vasuki Parbat with a small lake. The trek is steady upward. After Exploring the area, trek back to Nandanvan. Arrive in 5-6 hours and overnight stay in tents.

Today, we will retrace our steps from Nandanvan to Cheerwasa. Camp in Cheerwasa for the night.

After breakfast get ready to trek down to Gangotri. The descent is easy and one can reach Gangotri well before afternoon. We can use this day to visit the holy town of Gangotri which is one of the most famous and sacred destinations for Hindus, all over the world.

Leave from Gangotri in the morning and reach Dehradun till evening.
