Down to the Tamor river at Mulghat
A drive from Bhedetar down the far side of the ridge to Mulghat, where the Koshi Highway crosses the Tamor river, for a riverside walk, fried river fish and a feel for the deep valleys of the Koshi hills.

From Bhedetar the highway drops steeply north, through forest and farms, to Mulghat, a small riverside settlement where a bridge crosses the Tamor. The descent is dramatic: the cool ridge gives way to a warm valley floor in under an hour, losing roughly a thousand metres. Along the way, the road passes terraces, small villages and viewpoints over the deep valley of the Tamor and the hills of Dhankuta beyond.
The Tamor drains the Kanchenjunga region far to the north, and here it runs wide and green over boulders in the dry season. We walk along the banks, watch the traffic cross the bridge, and stop at a riverside stall for fried fish and tea. Our guide explains how the Tamor joins the Arun and Sun Koshi downstream to form the Sapta Koshi, the river you saw shining on the plains from Bhedetar.
Then we either climb back to Bhedetar or carry on up the other side to Dhankuta and Hile, making this a natural part of the journey north rather than a separate trip. In the dry months the riverside is pleasant and warm; in the monsoon the river is high, brown and dangerous, and we keep well back from the water. Either way, the drive shows how deeply the rivers cut these hills.

Questions
Where is Mulghat?
Mulghat is a small settlement on the Tamor river, where the Koshi Highway crosses between Bhedetar and Dhankuta. It sits much lower than both, in a warm river valley, roughly under an hour's drive from Bhedetar.
Can I swim in the Tamor at Mulghat?
We do not recommend it. The Tamor is cold and fast with strong currents, especially from May to October when snowmelt and monsoon rain swell it. Paddle only at the edge in calm water in the dry season, and stay away in the monsoon.
Where does the Tamor river come from?
The Tamor rises in the Kanchenjunga region of Taplejung, flows south through the eastern hills past Mulghat, and joins the Arun and Sun Koshi to form the Sapta Koshi, which crosses the Terai into India and joins the Ganges.
