Spanning an area of 175 square kilometers, this protected region is nestled in the floodplains of the Koshi River and serves as a vital refuge for diverse flora and fauna. Established in 1976, the reserve was primarily created to protect the endangered wild water buffalo, locally known as “Arna”, and has since become a sanctuary for countless species.
