Overview
Hum Hum Waterfall (locally known as Hamham Jhorna or Cheetah Falls) is widely celebrated as one of the most thrilling, untamed, and picturesque backcountry adventure destinations in Bangladesh. Hidden deep in the heart of the pristine Rajkandi Reserve Forest in Kamalganj upazila of Moulvibazar district, near the international border with Tripura, this majestic waterfall plunges approximately 150 feet (45 metres) down a sheer rock face.
The waterfall features a striking double-tiered structure. Water gushes from virgin rainforest springs above, tumbling over moss-carpeted boulders into a serene, shallow rocky amphitheater before cascading into a downstream gorge. The deafening roar of rushing water and cool airborne mist spray create an enchanting sanctuary in the deep forest.
Reaching Hum Hum is an unforgettable expedition. Starting from the remote tribal village of Kolabon Para, trekkers embark on a strenuous 2.5 to 3.5-hour trek through dense tropical jungle, climbing steep muddy hill ridges (Pahar trail) and wading through waist-deep, pebble-bedded mountain streams (Jhiri trail) filled with wild bamboo groves and ancient ficus trees.
For intrepid trekkers, nature photographers, and eco-adventurers, Hum Hum Waterfall offers one of the purest and most exhilarating wilderness experiences in Bengal.
History & Culture
Discovered by adventurous university trekking groups in 2009, the waterfall was previously known only to local indigenous Khasia and Tripura forest foragers who revered the cascade.
The name 'Hum Hum' mimics the resonant, humming roar of water echoing through the deep forest canyon during monsoon floods.
Local indigenous youth from Kolabon Para have since formed community eco-guide associations, assisting travelers while advocating for forest conservation.
