The initial segment of the day promises an exhilarating and captivating journey to Taluka, the starting point of our trek. Embarking on this day of adventure, you will traverse a mesmerizing blend of woodlands and follow the graceful path alongside the Supin River.

The ensuing stroll is marked by a delightful sense of ease, as much of the path maintains a gentle level. While the initial trail might present some inclines, the promise of the breathtaking panorama ahead eclipses any challenges. Within just thirty minutes, we'll find ourselves encompassing not one, but two serene lakes. These two locations are united by a graceful wooden bridge.

Beyond the curve of the mountains and the bridge's traverse, an expansive front unfolds, adorned with meadows aplenty. This juncture serves as the launching point for an expedition that navigates the twists and turns of the encircling peaks, amidst wide fields adorned with stones and hillocks. An improvised wooden bridge emerges ahead, providing a vantage to behold the Supin valley stretching above.

Despite the captivating vistas, the ascent intensifies from this juncture onward. Our subsequent destination is Kalkatiyadhaar, nestled at a height of 2,692 meters. Here, under the canopy of Kalkatiyadhaar, we'll find rest for the night, embraced by the quietude of the elevated haven.

Each twist and turn along the trail unveils majestic pine trees that stand tall and welcoming.

As you venture forth, the trail ascends through varying inclines and levels of challenge before revealing the enchanting Har Ki Dun valley. For those daring to ascend further, a realm of frozen waterfalls and snowy landscapes awaits, these icy fields retaining their wintry charm throughout the entire season. The valley emerges as an ethereal haven, seemingly plucked from celestial realms upon first glance.

The grandeur of the surroundings truly comes to life, with vistas that extend from colossal peaks like Swargarohini, Hata Mountain, to the commanding presence of Black Top – each panorama leaving you breathless in sheer admiration.

The dawn heralds the commencement of a five-hour expedition to Taluka. During this journey, you will ascend the well-trodden path, making customary pauses at familiar rest points. As you reach the terminus of the gravel road, the awaiting vehicle stands ready to transport you back to the base camp.

Exercise caution regarding a technique referred to as the "falling approach." While descending may be less demanding, it's advisable not to subject your footwear to excessive strain by taking overly large strides.
