You will be picked up from the Dehradun station. You will begin a beautiful road trip along the Tons river, and passing villages in Uttarakhand like Damta, Purola, Mori, and Netwar. On arrival at Sankri you will check in to a homestay, unwind and relax. This beautiful quaint village of Sankri is the base camp for many treks and has good uninterrupted views of the Himalayan ranges. You can visit the market if you want to buy the trekking equipments or anything essential for your trek.

Post breakfast you will be driven to Taluka the last motorable road in Govind Pashu National Park. You start your trek from here alongside the Supin river passing by the Gangad village all the way to the quaint village of Osla. Home to about 200 families, it gives us a peek into Garwahli culture. Seema is a tiny settlement opposite to Osla on the other side of the river. We set camp here or stay in a hut with a local family in the village.

Leaving the last last village behind you trek towards to a beautiful meadow – Devsu Thatch. From here you can see the Swargarohini ranges, Kalanag (Black Peak) (6387m) straight ahead. On your left, you can see Har Ki Dun Valley. After descending from the meadow, you enter the Ruinsara valley. At the end of today's trek, you will camp beside the stream close to the waterfall locally known as Roiltigad or Roiltia.

Today, Post a good 2 hours trek you will reach one of the highlights of the trek — Ruinsara Tal, an alpine lake, surrounded by widely spreaded Rhododendron trees, with their distinct pink bloom in the summers. It is one of the trio of lakes in the Garhwal region, the other two lakes being Marinda and Maldaru. We will be camping overnight near the lake.

It is good to acclimatize at an elevation of about 3500 m before reaching Bali Pass base camp the next day. You can spend the day exploring nearby places. One can trek towards the Banderpunch glacier or Kyarkoti which is the base camp for Kalanag and Dumdar Kandi pass. We return to the camp in the evening.

Post an early breakfast you start the trek towards Odari with an aim to reach before afternoon. We descend down to the shallow river bed, cross over to the opposite bank and walk uphill to another beautiful meadow – Thanga. This meadow also offers awe-inspiring views of the Swargarohini ranges. On arrival at Odari unwind and relax. The word ‘Odari’ means a naturally made cave rock. This place has a mythological story associated with it. It is believed that Bali, Hanuman’s brother, had stayed here for one night. Here you camp right below the Bali Pass along a glacial moraine. This is the one of the best locations for a camp, with the valley below and the Pass behind us. The temperatures at night tend to go to sub-zero degrees. Camping at this altitude is a unique experience which very few treks offer.

Today you will cross the Bali Pass down a steep ridge. We strive to reach the summit by 8am. It is a fairly short but steep climb up to the Pass. A lot of glacial scree will be encountered here. Time taken to reach the top ranges from 45 minutes to one and a half hours. At the pass you will see an uninterrupted view of the Himalayan ranges along with hints of the Saptrishi Kund, which is the origin of river Yamuna. We also get to witness the Banderpunch peaks from the top of the Pass. The summits of Dayara Bugyal, Barua Top and Dokrani Bamak are visible too. We then descend carefully towards the camping grounds of upper Dhamni.

We descend further to a forested trail. This path leads us to the famous shrine of Yamunotri with the glorious Bandarpunch in its background. One of the temples in the Char Dham circuit, it is dedicated to Goddess Yamuna. After paying obeisance to her black marble idol, we make our way down the conventional pilgrim road to Janki Chatti. We stay overnight in one of the guesthouses here. We will get electricity but no phone network.

Today you will be driven back to Dehradun.
