Rupin Pass begins in Uttarakhand’s Dhaula village and crosses into Himachal’s Sangla valley, passing through hanging villages, waterfall-fed valleys, and a genuinely steep snow wall climb near the 15,250 ft pass that has made this one of the most talked-about crossing treks in the western Himalayas.
Route Overview
The route runs from Dhaula through Sewa, Jhaka, and Saruwas Thach to Rupin Pass, before descending via Ronti Gad into Sangla, typically completed over 8 days given the distance and terrain variety covered.
Day-by-Day Breakdown
The early days from Dhaula through Sewa and Jhaka follow a scenic river valley trail passing several waterfalls and traditional hanging villages built into steep hillsides. The middle section toward Saruwas Thach gains altitude through increasingly alpine terrain, setting up for the pass-crossing day itself, which includes the trek’s signature near-vertical snow wall section, often roped by guides for less experienced trekkers. The descent via Ronti Gad into Sangla completes the crossing into Himachal’s Kinnaur-adjacent valley, offering a markedly different landscape from the Uttarakhand side.
Best Time to Visit
Mid-May to June, and September, are the recommended windows, with late spring offering more dramatic snow conditions at the pass and autumn offering clearer long-distance views.
Difficulty and Fitness Preparation
This trek is rated Moderate-Difficult, with the snow wall section requiring steady footing and often roped by guides for less experienced groups. Trekkers should have completed at least one prior high-altitude trek and possess solid general fitness, given the combination of long daily distances and the technical nature of the pass-day snow climb.
Permits and Regulations
Forest permits are required on both the Uttarakhand and Himachal sides given the cross-state nature of this trek, and this is typically handled by the operator as part of a standard group booking.
What to Pack
Given the snow wall section, gaiters, sturdy waterproof boots with good grip, and trekking poles are all strongly recommended, along with a warm, windproof layer system for the exposed pass crossing itself. A headlamp and basic navigation backup are useful given the trek’s length and remoteness in its middle sections.
Where to Stay
The trek is camping-based for most of its length, with basic village stays possible at Dhaula and Sangla at either end, and tented camps arranged by operators at Sewa, Jhaka, and Saruwas Thach along the route.
Flora, Fauna, and Landscape Notes
The trail passes through Jhaka, a wooden-house village clinging to a cliffside, considered one of the most photogenic villages on any Himachal trek route, along with numerous waterfalls fed by glacial melt higher up the valley. The transition from Uttarakhand’s greener, forested terrain to Himachal’s more open Sangla valley landscape on the far side of the pass adds a distinct geographic variety to this trek beyond the technical challenge of the crossing itself.
Frequently Asked Questions
Is the snow wall dangerous? With appropriate guide support and roping for less experienced trekkers, the snow wall section is manageable, though it remains one of the more technically demanding moments on any moderately-rated Himachal trek. Can this trek be done independently? Given the cross-state permits required and the technical pass-day section, going with an experienced registered operator is strongly recommended over an independent attempt. Which direction is better to trek — Dhaula to Sangla or the reverse? Most operators run the trek from Dhaula to Sangla as described, since this direction offers a more gradual buildup in altitude before the technical pass day.
Getting There
Dhaula, the starting point in Uttarakhand, is reached via Dehradun and the broader Garhwal region road network, while the Sangla endpoint in Himachal connects back to the main Kinnaur valley road, making this one of the few treks in this list that genuinely spans two different states.
Nearby Attractions
Sangla itself, along with the nearby Chitkul village, often considered the last inhabited village before the restricted border zone, are popular additional stops for trekkers completing the Rupin Pass crossing and looking to extend their time in this part of Kinnaur.
Practical Tips
Given the cross-state logistics and technical snow wall section, booking with an operator experienced specifically in running this exact route, with established permit arrangements on both sides, is considerably more important here than for single-state treks closer to Manali.
Safety Considerations
The snow wall section near the pass is the primary safety consideration on this route, and trekkers should follow their guide’s roping and footing instructions closely rather than attempting to navigate this section independently, regardless of prior general trekking experience.
