Tarsar Marsar Trek, Kashmir, India

Tarsar Marsar Trek — Overview

The Tarsar Marsar Trek is Kashmir’s finest crossover trek — a point-to-point journey that begins in the Lidder Valley at Aru and ends in the Sind Valley at Sumbal, threading through three high-altitude lakes, two mountain passes, and a landscape that consistently stops trekkers mid-stride.

The route visits three of Kashmir’s most beautiful alpine lakes in sequence: Tarsar (3,780m) — almond-shaped and electric blue, set in a meadow bowl below the ridgeline with Kolahoi Peak (5,425m), the highest peak in Kashmir, framing the sky above; Sundarsar (3,850m) — smaller and quieter, ringed by wildflower slopes; and the formidable Marsar (4,010m) — a closed cauldron lake perched high above the surrounding valleys, rarely without a cap of cloud, with a reputation among local shepherds that has earned it the name of Tarsar’s dark twin. From Marsar, the trail crosses the Sonmasti Pass at 4,100m — the watershed between the Lidder and Sind drainages — and descends in a long sweep through the Sonamasti Valley, past cascading waterfalls and terraced shepherd meadows, to the roadhead at Surfraw.

Unlike loop treks that return to the same trailhead, the crossover format means every step is new terrain. You walk into the heart of the Overa-Aru Wildlife Sanctuary from the south, traverse its high lakes and passes, and emerge from the north into a completely different valley — the Sind corridor leading back toward Srinagar. Summit Routes is based in Srinagar and has been running this route since 2011. Our guides are Kashmiri and know every campsite, stream crossing, and weather pattern on the Tarsar Marsar corridor.


Important Notes

  • Best Season: June to September. The route is typically open from late May depending on snowpack, and the peak wildflower bloom at Tarsar and Shekhwas runs from late June through mid-August. September is the clearest month for views. The route closes with the first heavy snowfall — typically early October.
  • Difficulty Level: Moderate to Challenging. The trek has two demanding days: Day 5 (Tarsar Pass crossing, 300m ascent from the lake) and especially Day 6 (Marsar traverse + Sonmasti Pass at 4,100m + 600m+ descent to Sonmasti camp) — the hardest day of the trek. Prior multi-day trekking experience above 3,000m is recommended. Read our guide to altitude sickness in the Himalaya before departure.
  • Trek Type: Crossover — point-to-point from Lidder Valley (Aru) to Sind Valley (Sumbal). Not a loop. You begin and end at different points; the drive back to Srinagar is arranged from Sumbal on Day 7.
  • Highest Points: Sonmasti Pass at 4,100m (Day 6, the true high point) and Marsar Lake at 4,010m (Day 6 en route to the pass). The highest camp is Sundarsar at 3,850m.
  • Fully Camping: All nights on trek are under canvas — there are no teahouses, lodges, or dhabas above Aru on this route. Summit Routes provides dome tents, sleeping bags (rated to -10°C), sleeping mats, dining tent, kitchen tent, toilet tent, and a dedicated cook. You need only bring personal clothing and a daypack.
  • Overa-Aru Wildlife Sanctuary Permit: Entry into the sanctuary is mandatory and requires a trekking permit. Summit Routes arranges this on your behalf before departure. See our permits guide.
  • Fitness Standard: Must be comfortable trekking 5–15 km daily on mountain terrain with significant elevation gain. Day 6 is a 9 km day with two passes and a 600m+ descent — physical preparation for this day specifically is important.
  • Cultural Note: The Aru and Lidder Valley communities include Bakarwal shepherds whose seasonal migration routes cross the Tarsar Marsar corridor. The meadows at Shekhwas and Sonmasti are traditional grazing grounds. Please respect all camps, flocks, and grazing land encountered on the route.
