Spreading over 340 sq. kilometers (130 sq. miles) and a further 425 Sq. kilometers (164 sq. miles) as buffer zone around it Dibru-Saikhowa is the largest wildlife park in Assam. The park was originally proposed to protect the extremely endangered White-Winged Wood Duck in its natural habitat.
Dibru-Saikhowa National Park known for its rich biodiversity, especially with the 350 or so species of migratory and aquatic birds are located in this district. The national park is hotspot of many rare species of wildlife including the Royal Bengal Tiger, Sloth Bear, Gangetic Dolphin, Crested Serpent Eagle, Spot Billed Pelican and White Winged Duck.
The encircling branches of Brahmaputra flows around the floodplains and offers a unique safe heaven for the wild life. This river and monsoon drenched semi wetland offers one of the stunning and pristine sceneries in Assam.
Though not a rare species, the wild-turned-domesticated-turned (again!) wild Feral Horses can invoke some curiosity. Along with other war memorials, these horses are the living legends of the World War II . These horses escaped from the army camps during the war. Now they are a kind of semi wild animals living in the vicinity of the national park.
Access to the park is regulated. The national park is open for tourist typically during November to April. There are two entry points for the tourists - Guijan at the south border and Dhola ( Saikhowa ghat ) and the northern periphery of the sanctuary. Both are accessible by bus, taxi or Auto-rickshaws from Tinsukia . Distance from Tinsukia to Guijan and Dhola entry points are about 10km and 50km. Then you need to cross the river to enter the park.
Tinsukia is the right base to tour the park as Guijan has only limited accommodation facilities.
