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 Sun Kosi Raft Trip or with treks in the eastern hills or with Darjeeling/Sikkim extension.
