Koshi Tappu Wildlife Reserve is situated eastward in the plain lands of the country. The idea behind the establishment of this wildlife reserve was to protect rare wild water buffaloes. The reserve covers an area of 175 square km to the north with a kilometer long extending barrage that spans the Koshi River. The vast expanse of water offers wonderful wetlands that inhabit many species of birds and migrant birds. It is one of the best bird watching sanctuaries of Asia.
It is heaven for those who like to explore grassland, river lagoons, and woodlands on foot. Tourist can reach this area by three routes air, road, and water. Among three routes, air is most preferred one as it is 45 minutes flight to Biratnagar from Kathmandu. And, from Biratnagar, it takes around one and 1 hour drive to reach the camp. By road, it takes 12 to 14 hours from Kathmandu. The water route is a bit challenging. Rafting down for 8-10 days from Sun Koshi river is the very thrilling route to reach the destination and this is a least preferred route.
