Rupin Pass

Rupin Pass is universally ranked among the top five classic high-altitude crossover treks in the entire Indian Himalayas, situated at an altitude of 4,650 metres (15,256 feet) above sea level in the Great Himalayan Range. Located at coordinates 31.3500° N and 78.2000° E, the pass occupies a dramatic, narrow notch that straddles the interstate boundary connecting the rugged, forest-draped Rupin River gorge in Uttarakhand (Garhwal) with the idyllic, culture-steeped Baspa (Sangla) Valley of Kinnaur in Himachal Pradesh.

What elevates Rupin Pass into legend is its constantly transforming scenery. Starting from the tiny village of Dhaula at 1,580 metres, the trail ascends through hanging villages clinging to vertical cliffs, traverses narrow gorge bridges suspended over roaring white-water rapids, emerges into wide glacial valleys carved by prehistoric ice, and ascends beside a colossal three-tiered waterfall before terminating in a dramatic amphitheater surrounded by towering granite horns.

The trek spans 7 to 8 days, beginning at Dhaula in Uttarakhand and passing through Sewa (with its ancient, mysterious Kinnauri-style temple decorated with brass coins), Jiskoon, and Jhaka—a famous 'hanging village' built on a near-vertical cliffside. Beyond Saruwas Thach, the trail enters a snow-covered canyon where trekkers walk directly over massive, naturally formed snow bridges arching over the churning river.

The climax of the ascent is the Lower and Upper Waterfall camps, where the Rupin River drops hundreds of metres in thunderous cascades. The final summit push is an intense scramble through the steep 'Rupin Gully' over packed snow and loose scree to reach the pass crest at 15,256 feet, followed by a long, scenic glissade and descent into the alpine pastures of Sangla Kanda and the village of Sangla in Kinnaur.

The route has served as a vital pastoral trade and migration highway for centuries, used by Kinnauri traders and Garhwali pastoralists exchanging salt, wool, and agricultural produce.

Managed under the eco-tourism guidelines of the Govind Pashu Vihar National Park and the Himachal Pradesh Forest Department, the trail is protected to ensure sustainable alpine trekking.

The steep climb up the narrow Rupin Gully involves loose scree and hard snow. Trekkers must wear microspikes and climbing helmets to protect against rolling stones.

Snow bridges can become fragile in late summer; always follow the exact line tested by local guides.

Rupin Pass is an alpine trekking footpath. Standard passenger vehicles and taxis can access Dhaula via Dehradun, Purola, and Mori, while paved roads at Sangla connect to National Highway 5.

The exit through Sangla and Chitkul ('India's last village') provides a magnificent cultural finish to the trekking expedition.

Trek entry permits and eco-fees are paid at the Govind Pashu Vihar sanctuary barrier at Dhaula.

No special border permits are required for Indian citizens; foreign trekkers must carry passports for registration at forest posts.

The best seasons are late May to June (for thrilling snow bridges and snow slides) and September to mid-October (for golden meadows, crisp views, and dry trails).

July and August bring heavy monsoon rains in the lower gorge, while winter (November to May) brings deep avalanche snow that seals the pass completely.

The three-stage Rupin Waterfall is one of the most magnificent natural wonders in the Himalayas, roaring down sheer rock amphitheaters directly beside the high trekking camps.

From the summit saddle, trekkers enjoy an astonishing close-up panorama of the revered Kinner Kailash massif and the sweeping green folds of the Baspa Valley.

Rupin Pass is the premier inter-state trekking crossover connecting Uttarakhand's Garhwal region directly with Himachal Pradesh's Kinnaur Valley.
