Tarsar Marsar Trek covers 65+ km through Kashmir's most spectacular alpine terrain, connecting two high-altitude lakes via the stunning Sundersar Pass at 13,500 ft. Tarsar is fierce and open, Marsar is sheltered and mystical. Six demanding days through meadows, moraines, and shepherd trails — genuinely one of India's greatest trekking experiences, full stop. https://thinairexpedition.com/tarsar-marsar-lake-trek
