Overview
Before the construction of the motorable Manali-Leh highway in the 1960s and the engineering marvel of the Atal Tunnel in 2020, Rohtang Pass (3,978 meters) was one of the most celebrated, formidable, and feared foot crossings in the Himalayas. Deriving its somber name from the Persian words 'Ruh-Tang' (meaning 'Pile of Corpses') due to the countless traders, pilgrims, and muleteers who perished in sudden blizzard whiteouts while attempting the crossing, Rohtang serves as the primary meteorological divide between the lush, monsoon-drenched valleys of Kullu and the arid, rain-shadow deserts of Lahaul and Ladakh.
Trekking Rohtang Pass on foot allows modern hikers to experience the authentic historical soul of this ancient trans-Himalayan trade corridor. Departing from the meadow settlement of Marhi or the cascading waters of Rahla Falls, the old stone bridle trail bypasses the vehicular traffic jams of the road, cutting straight up the mountain spine through alpine pastures carpeted in yellow buttercups, wild anemones, and medicinal herbs.
Standing atop the 3,978-meter crest of Rohtang Pass reveals a breathtaking geographical contrast: looking south, lush green forests and drifting monsoon clouds billow over the Beas basin; looking north, the sheer glaciated pyramids of the Chandra-Bhaga range and the jagged peaks of Lahaul rise under crystal-clear trans-Himalayan skies. A small stone shrine dedicated to the sage Maharishi Ved Vyas (the mythical origin of the Beas River, known as Beas Kund) stands near the crest.
Descending the northern slopes down to Gramphu brings hikers directly to the roaring Chandra River, providing an exhilarating sense of having crossed a true continental divide entirely under human power.
