Nature view of Koshi Tappu Wildlife Reserve

The Koshi Tappu Wildlife Reserve is a protected area in the Terai of eastern Nepal covering 175 km2 (68 sq mi) of wetlands in the Sunsari, Saptari and Udayapur Districts. It comprises extensive mudflats, reed beds, and freshwater marshes in the floodplain of the Sapta Kosi River, and ranges in altitude from 75 to 81 m (246 to 266 ft). It was established in 1976 and designated as a Ramsar site in December 1987.

A primeir location in Nepal for bird watching.The Kosi Tapu and the Kosi Barrage in east Nepal provide one of the best places in Nepal to view migratory water fowl, waders and shore birds during the winter months. Many species not recorded elsewhere in the region have been seen here. Thousands of birds congregate here in January and February before they migrate north when the warm weather begins. Kosi Tapu Tented Camp situated on the fringe of the reserve provides the only accommodation to date. Well qualified nature guides take the guests out on walks, jeep drives and boat rides to look for birds and the wild buffalo found only here in Nepal. It is possible to combine this tour with SunKosi Raft Trip or with treks in the eastern hills." -timetotime t (Tripadvisor)
