Koshi Tappu Wildlife Reserve established with the main aim to protect the rare wild water buffaloes in 1976. Total Area of Koshi Tappu Wildlife Reserve extends to 68 sq mi. km to the north with a one-kilometer long barrage that spans the Koshi river. The vast expanse of water created by the barrage, marshes, lagoons, mudflats and arable land that lie around it offers an outstanding wetland which has created one of the best and finest bird watching sanctuary in Asia.
One of the most rewarding and greatest assets of Koshi Tappu Wildlife Tour is that it offers ample scope for nature walks. For those with curiosity and perseverance, walking on foot is the most profitable way of exploring the grassland, river lagoons and woodlands.The best time to visit this fabulous wildlife reserve is between October to March when many of the migratory and local birds can be seen by the barrage and many of the river channels. Numerous Himalayan peaks including the Makalu I (8,463m), the fifth highest mountain in the world, can be seen during these months.
The Koshi Tappu Wildlife Tour can be start by air, land and river. It is just 45 minutes flight to Biratnagar from Kathmandu and then a mere one and half hours drive to the camp. Rafting down for 8-10 days on the wild stretches of the Sun Koshi River is another exciting way to reach the destination. The third option would be the scenic drive through the meandering country roads, about 500 km, that takes almost 10 hours from Kathmandu. Koshi Tappu Wildlife Reserve also makes an exciting alternative destination of visitors who have already visited Royal Chitwan National Park and Bardia National Park.
