Located near Robir bazar of Kulaura Upazila in Moulvibazar District, it is only 3–4 hours trekking distance from Azgarabad Tea Estate. This peak is also accessible from Rajki tea estate near Fultola bazar of Juri Upazila. The hill range of Kala Pahar is locally known as Longla Range. 'Kala Pahar' is the local name of the highest peak. According to Bangladesh Geographic society this hill is also known as 'Hararganj pahar'. In Bengali language 'hill' word means 'Pahar'. Situated in the north-eastern part of the country 60% of the range is in Bangladesh and the rest is in the Northern Tripura state of India. In Tripura, part of this hill is known as Raghunandan pahar. The famous ancient religious archaeological site of India 'Unakoti' lies at the foot of this hill.
