The Gandak — the Narayani in Nepal — is one of the great Himalayan rivers, rising on the Tibetan border and cutting through the Mahabharat range before it bursts out onto the plain at Triveni, where three streams meet and India begins. The 1960s barrage that spans it here irrigates both countries, and the pool above it and the braided channels below have become a small, serious water-sports destination.
Bihar Tourism launched rafting on the Gandak in 2023: Grade I–II rapids over a 6–8 km stretch below the hills, gentle enough for first-timers and families, with kayaks, canoes and motorboats on the calmer reaches. The real wildlife is in the water — the Gandak holds the largest population of gharial in India outside the Chambal, released here by the Forest Department since 2014, and Gangetic dolphins surface in the deeper channels. Early-morning boat safaris from the eco-park find both.
On the bank, Valmikinagar is a plain, friendly town with a very old story: tradition places Valmiki's ashram here, where Sita lived in exile and Lava and Kusha were born, and the Triveni confluence is a bathing site on Makar Sankranti and Shivratri. The Nepal border post is a short walk; the Shivalik hills, the forest and the tiger reserve are at your back; and in winter the whole place has a cool, clear, Himalayan light. Pair it with the tiger reserve for Bihar's best wild long weekend.
Chapter 01
How it came to be
The Gandak comes out of the Himalaya through one of the deepest gorges on earth, between Dhaulagiri and Annapurna, and arrives at the plains here at Triveni, where it is joined by two smaller streams and crosses into India. The Gandak Project barrage, built jointly by India and Nepal between 1959 and 1969, turned the border town of Bhainsalotan into Valmikinagar — named for the sage whose hermitage tradition places on this bank, where Sita bore Lava and Kusha.
Gharial, hunted nearly to extinction, were released into the Gandak from 2014 by the Bihar forest department and the Wildlife Trust of India; the river now holds the second-largest wild population in the world. Rafting began in 2023 as part of the state's push to make the Champaran forest a destination.
Chapter 02
What it's like now
The river is the attraction and the forest the backdrop. Mornings go on the water: a boat below the barrage at first light finds gharial basking on sandbars, their long snouts raised, and dolphins rolling in the channels. Then the raft — a bright, bouncing hour down Grade I–II riffles with the Shivaliks on your right and Nepal on your left, gentle enough for children and grandparents.
Afternoons are for the barrage walk, the Triveni ghat, the ashram, and the Valmiki tiger reserve's safari gates ten minutes away. Nights at the eco-huts are cold, dark and loud with forest. It is the wild weekend Bihar never knew it had.
