It is located in the northern Myanmar state of Kachin in an outlying subrange of the Greater Himalayan mountain system near the border tripoint with India and China. Its highest status has recently been challenged by 5,870-meter (19,260 ft)-tall Gamlang Razi, located about 6.6 kilometers (4.1 mi) WSW on the Chinese border.

Hkakabo Razi was established as a natural reserve on January 30, 1996, and as a national park on November 10, 1998. The Khakaborazi National Park is the last stronghold for biodiversity in Myanmar.

The peak is enclosed within Khakaborazi National Park. The park is entirely mountainous and is characterized by broad-leaved evergreen rain forest, a sub-tropical temperate zone from 8,000 to 9,000 ft (2,400–2,700 m), then broad-leaved, semi-deciduous forest and finally needle-leaved evergreen, snow forest.

The summit of Hkakabo Razi has an alpine climate (Köppen climate classification) with abundant snowfall more commonly than rain in winter. During the 2009 cold spell, the lowest temperature recorded in Myanmar was -57.9 °C (-72.2 °F), the highest was 23 °C (73 °F).

Takashi Ozaki (Japan, 1951 – May 14, 2011) and Nyima Gyaltsen (aka “Aung Tse”; Myanmar) made the first ascent in 1996.
