Bangladesh is primarily a low-lying country. The main areas of elevation are the Chittagong Hills in the southeast, the Low Hills of Sylhet in the northeast, and certain highlands in the north and northwest. Kala Pahar, at , is the highest peak in the Sylhet range and also the highest point in northern Bangladesh. The Chittagong Hills, which are the only significant hill system in the country, contain at least seventy-five mountain peaks, which range in altitude approximately from above sea level. The highest point in the Chittagongs and Bangladesh is at at Saka Haphong in the Mowdok mountain range.
Saka Haphong
Saka Haphong is the Tripura tribal name which is the highest peak of Bangladesh. The peak is at an altitude of , as recorded in 2006 by English adventurer Ginge Fullen. Saka Haphong is located at in the Mowdok mountain range on the border with Myanmar.
Zow Tlang/ Reang Haphong
Zow Tlang or Reang Haphong is a peak in the Mowdok range located at on the border with Myanmar. Its peak is at an altitude of . According to Bangla Trek, it is the second-highest peak in the country, though it has not yet been officially recognized by Bangladesh's government.
The local name comes from the Bawm language. The name 'Zow' refers to 'Mizo', a derivative of Mizoram in India. 'Tlang' means mountain in the Bwam language. The official name, 'Mowdok Mual', comes from American and Russian topographic maps.
Aiyang Tlang
Rama Manikya Haphong/Aiyang Tlang is another mountain found in Bangladesh nearing the Bangladesh–Myanmar border.
Van Rausang Bawm from the local 'Bawm ethnic community', Dalian headman Para of 'Remakri' Mouja, Thanchi Upozila in the Bandarban district was the one to discover it. On the 13th of November, 2019, Engineer Jyotirmoy Dhar had become the first Bangladeshi to have climbed the mountain.
Dumlong/ Msha Panji Haphong
In 2011, Wadud Mohosin Rubel alongside his three travel partners Asif Aminur Rashid, Nagib Meshkat and Abdul Haque have claimed the mountain, 'Dumlong/Msha Panji Haphong' to be the second highest mountain in Bangladesh on the basis of measurements made by their Garmin GPS. The height was found at 3,314 ft. (1,010 m). The location was recorded as 22°02′02.1″N 92°35′36.3″E, accurately matching the coordinates given by Google Earth.
A few months after this expedition, a team of Bangladeshi travelers led by Zaqiul Deep measured the height at 3,312 ft. (1,009 m). A third team also reached the summit later led by Fahim Hasan of BD Explorer. There is no doubt about the height of Dumlong but whether it is the second or third highest mountain in the country is yet to be confirmed. Nevertheless, it is indeed the highest peak of Rangamati Hill District and one of only three mountains measured at more than a thousand metres in height.
In 2014, several teams climbed the summit of Zow Tlang, and based on their readings, they surmised Dumlong is the third-highest mountain in Bangladesh.
Keokradong
Although it is widely reported to be the highest point in Bangladesh at , recent SRTM data, GPS readings and Russian topographic mapping show that its true height is less than .
On the top of Keokradong there is a small shelter and a signboard put up by the Bangladeshi military proclaiming the altitude to be . Garmin GPS recorded at this location, a different team measured with accuracy by GPS, a measurement consistent with Russian topographic mapping and SRTM data. It is at . USGS and Russian mapping dispute the claim that this is the location correctly named Keokradong; they show Keokradong at an summit further north.
Maithaijama Haphong
Located at the south-eastern part of Chittagong hill tracts between the Bangladesh and India border, Maithaijama Haphong is the sixth-highest peak of Bangladesh. However it is not officially recognized according to the Bangladesh government. This peak is also the second-highest peak of Reng Tlang range after Dumlong. On 7 December 2014 Fahim Hasan from Dhaka, a member of an adventure team BD Explorer with the help of the local villagers summitted the peak of Maithai Jama Haphong and measured this height as by the Garmin GPS device for the very first time. Exact Geo location of the highest point was N 22°00.714', E 92°35.863'. The name "Maithai Jama Haphong" came from the Tripura language. which means, "Bad hilly place for vegetation." Stream (Jhiri) route to summit & view from the peak is extraordinary. Location: Bilaichori, Rangamati. Range: Reng Tlang Elevation: (GPS accuracy: 2 m +/-) Position: N 22°00.714', E 92°35.863' Measured by: BD Explorer
