Altadighi National Park, National park in Dhamirhat, Naogaon, Bangladesh

Altadighi National Park is a 264.12-hectare forest of sal trees in Dhamirhat upazila, Naogaon district, near the Bangladesh-India border. At its centre lies the Altadighi tank, about 43 acres (1,100 m long, 500 m wide), with raised, hill-like banks and a southern shore covered in sal forest. The Ministry of Environment and Forests declared the park in 2011.

The protected area was officially established in December 2011 and represents Bangladesh's commitment to preserving natural spaces. The Forest Department has managed conservation efforts in this territory since its designation.

The name Altadighi comes from a local legend: King Bishwanath dug the tank for his mother, and ministers stopped her endless walk by scattering alta (red dye) on her feet, claiming they bled. The tank is thought to date from the Hindu-Buddhist period, contemporary with Jagaddal Mahavihara or earlier than the Pala era. Today it is leased to contractors, a practice experts see as a threat to the area's environment and biodiversity.

The best approach is to take a train to Rajshahi, then a bus to Dhamirhat, and finally an auto-rickshaw to the park. The dry season offers easier access to paths and more frequent wildlife sightings than other times of year.

The pond is about 1,100 m long and 500 m wide, with raised, hill-like banks and a southern shore covered in sal forest. Experts consider the leasing of the pond to contractors a threat to the area's environment and biodiversity.
