Terai ecosystem comprises a mesmerizing mosaic of Sal and Teak forests, lush grasslands, steaming swamps and wetlands. It is shelter for the number of endangered and critically endangered species. It is among the few places that have retained their natural character. There are no private resorts or hotels within the reserve forest. The movement of traffic is sparse. The people who live within the forest are largely native tribals.
The forest is largely untouched, away from civilization and quiet. It is the perfect getaway for those seeking a brief vacation amidst the calls of birds, thick forests and – if they are lucky and patient enough – a sighting of wildlife.
The Gairwa river which flows in the sanctuary area is declared as a sanctuary for crocodiles and alligators. It is also home to rare turtles, freshwater fish and a host of aquatic life. The river presents a scenic view on both banks with long forest tracts running into distance and overhanging trees on the river bank creating coves that attract visitors on motorboats.
