Sunsari सुनसरी

Sunsari sits at the foot of the eastern hills where the Koshi River valley opens onto the Terai, its main draws concentrated in two very different towns. Dharan, at the hill-edge, is an unusually lively mid-sized Nepali city — the site of a former British Gurkha recruitment depot — and the Buddha Subba temple above the town, reached on foot through the bazaar, is a significant Limbu and Hindu pilgrimage site. At the district's eastern margin, the Koshi Barrage — 56-gate flood-control and irrigation infrastructure built between 1958 and 1962 under a Nepal-India treaty — controls the Sapt Koshi's flow and anchors the Koshi Tappu wildlife ecosystem just downstream.

Inaruwa, the administrative headquarters, is a quiet crossroads town on the Mahendra Highway between Biratnagar and the eastern hills; Itahari, larger and busier, is a major road junction. Sunsari works well as a one-night transit between Biratnagar and Dhankuta or Taplejung, but Dharan rewards a longer stop for travellers with an interest in Limbu culture and eastern-hills history. The climate is warm and tropical in the Terai section, cooler in Dharan's hill setting; October to March avoids the worst heat.
