Ruinsara Lake Trek Overview:

In Uttarakhand, a lake is called 'tal'; such as Saru Tal, Maldaru Tal, Baradsar Tal, etc. Hence, Ruinsara Lake is called Ruinsara Tal by the local villagers. If you have ever gone on the Har ki Dun trek, you must have heard about Ruinsara Lake. Some trekkers like to walk long distances during the trek; they include exploring Ruinsara Lake along with the Har ki Dun Trek. However, not everyone is fit enough to complete that trek in 6/7 days. We have designed this trek considering the requirements of those enthusiastic trekkers who want to explore the beauty of Mother Nature but are not willing to walk long distances every day. Ruinsara is an alpine lake lying in the Har ki Dun valley in the Garhwal Himalayas. Ruinsara Tal remains surrounded by beautiful vast meadows. This lake is special as it is almost in the middle of the Har ki Dun Valley and Yamunotri Valley. By embarking on this trek, you will pass through some remote Himalayan villages, spectacular meadows like Devasu Bugyal, and lush green forests of pine, maple, rhododendrons, and Bhojpatra. Have you heard about Bhojpatra? It's a very sacred and interesting tree for spiritually inclined trekkers. When paper was not invented, our great ancestors and scholars used to write scriptures like Ramayan and Mahabharat on the bark of the Bhojpatra tree. Some ancient Hindu scriptures still remain intact. Let's get back to the trek. If you start walking further to your right, the trail will lead you to the Bali Pass Trek. There are other offbeat and adventurous treks that you can embark on from the Ruinsara Lake like Black Peak, Bandarpoonch, Swargarohini Base Camp, Dhumdhar Kandi and many others. This trek offers you a great opportunity to explore ancient Himalayan villages of Uttarakhand like Osla and Gangaad. You will be touched by the simplicity and humility of the villagers. Despite leading challenging and tough lives with limited resources, they always wear smiles on their faces and take delight in welcoming strangers. Their beautiful homes, constructed of wood and stone in ancient Himalayan architecture, always remain filled with the beautiful aroma of deodar trees. If you ever get the opportunity to stay in a homestay with such pure-hearted humans, don't miss it. You will not feel like going back home. Once you return from the trek to your city life and think about the divine mountains of the Himalayas and this trek, you will realize that "There is so much beauty to look after." Overall, this trek is truly diverse and beautiful. Come... Join us on this adventurous Ruinsara Lake Trek.


We start early from Dehradun and reach the village Sankri by evening. The final stretch is through the Govind Pashu National Park after we cross a check post at Netwar. We rest at night in a guest house or in camps.

Post breakfast we are transported from Sankri to Taluka. The drive is a bit bumpy. The trek commences from Taluka on a stony path. With the river Supin gushing through rapids beside us, under the shade of walnut, pine and other trees, the walk is quite pleasant. Often the passing villagers greet us on the way.

The path crosses over a few streams which merge with Supin. After a few hours of walk the village of Gangad can be seen towards the left, across the river. We continue our hike and after about an hour’s walk, the quaint village of Osla unfolds itself. Seema is a tiny settlement opposite to the river from Osla. We set camp here or stay in a hut with a local family in the village.

On this day, we continue along the true right of the valley along the Tons river. The trail ascends through the fields and climbs high above the confluence of the Tons and Ruinsara gad. The walk through the forest is beautiful, with Kalanag (6387) visible straight ahead in the valley. We camp beside the stream and close to the waterfall.

We ascend into the Ruinsara valley. There is a stark difference in the vegetation with pine and fir giving way to birch and rhododendron. Ruinsara lake is a lovely lake surrounded by meadows and rhododendron bushes. It is considered sacred by the locals. Overnight in camps near the lake.

We spend some time near the lake and can hike further ahead. By late afternoon we return to the waterfall campsite. Camping is not allowed at the Lake due to its fragile biodiversity.

We trek the day at a very comfortable pace as we head back on the same route. We arrive at Devsu Bughyal, a small campsite tucked with towering hills on one side and tall pines on the other side.

Being the last trekking day with a long distance but overall descent, we start the day early and trek through Seema, Gangad village and finally arrive at Taluka before evening. We take a vehicle to Sankri and check into the Guest house over the night.

We drive back to Dehradun from Sankri. Arrive by late afternoon for overnight stay at Dehradun. Trekkers can further opt to stay at Mussoorie or head further to Rishikesh or Tapovan for a more spiritual end to the journey.
