We get an early start from Dehradun and travel all the way to Sankri, where we plan to arrive in the evening. After passing past a check station in Netwar, the remaining portion of the journey will take us through the Govind Pashu National Park. The guest house or one of the campgrounds is where we spend the night.

After finishing our breakfast, we will drive from Sankri to Taluka. The ride is a little rough in spots. The gravel route leading to the start of the walk is located in Taluka. The stroll is made more enjoyable by the sound of the Supin River crashing over rapids on each side of us, as well as the walnut, pine, and other trees that provide shade. On our route, we are often greeted by locals who are out and about. The trail goes through a several creeks, all of which eventually flow into Supin. After a couple of hours of hiking, the hamlet of Gangad can be seen to the left, located on the other side of the river. We go on with our trip, and after a little over an hour of walking, the picturesque town of Osla comes into view. Seema is a small community that may be found on the other side of the river from Osla. We either put up our tents here or make arrangements to stay in a hut with a local family.

We will begin our trek to Kalkattiyadhaar once we have had breakfast, and the first part of the path will take us down the left side of the valley and through some farms. The route continues on the right side of the valley after passing over a bridge that crosses the river Rupin. It then begins to ascent while passing through meadows, pastures, and houses. And now we have arrived at our destination: the ridge known as Kalkatiyadhaar. Following a rather quick descent from the mountain, we will arrive at our designated camping spot. We will have our meal and then retire to the conveniences of our tent for the night.

You should get up early and begin your trek in the direction of Har Ki Dun. The beginning of the path is very easy, but as it winds through the stunning meadows of Har Ki Dun, the ascent becomes much more difficult. A brook of modest size but constant flow passes near the campground. The wonderful quality of the glittering water is enhanced by the sun's rays as they reflect off of it. A vista like this one, which combines the vastness of the Har Ki Dun valley with the breathtaking scenery of snow-capped mountains rising up directly in front of your own eyes, is one that should be treasured for the rest of one's life. Return to the Kalkattiyadhaar camp after spending some time at the peak and taking in the breathtaking view of the scenery in front of you once you've spent some time there.

Get up early so you may see the captivating dawn and take in the breathtaking scenery of the Swargarohini peaks from the comfort of the camp. After getting an early start on breakfast, make your way back to Seema. We will begin our trek by going over the Har Ki Dun bridge, and then we will continue walking along the river. The ascent starts out slow and easy, and then it quickly begins to decline as it gets closer to Seema. If all goes according to plan and there is time left over, we will make a stop at the village of Osla, where you will be able to see the traditional Garhwali homes and the way of life of the people who live there. After a period of time has passed, you should continue your trek to Seema and spend the night there.

We started our journey towards Taluka at an early hour in the morning after saying our goodbyes to the Seema. We are transported back to Sankri by a car from Taluka, and once we arrive, we check into one of the camps or guesthouses there.

This is the last day of the trek to Ruinsara Lake, and we will depart Sankri in the morning to make our way to Dehradun by the late afternoon.
