During the Vietnam War the area around the mountain was a hot zone as the Ho Chi Minh Trail ended a few kilometers west across the Cambodian border.

The oldest Khmer myth involves a female deity, "Neang Khmau" who left her footprints on the mountain rocks.

Soon afterward, other helicopters deposited the battalion’s reconnaissance platoon on the mountain’s northern shoulder, from which they could observe the progress of Companies B and C and block any attempts by the VC to escape in that direction.

Rain during the night soaked the rocks, further impeding the infantry’s movement the next morning, but the troops reached the foot of the mountain unscathed.

The 80-man 3rd Company, 314th Regional Force Battalion guarding the radio relay station on the summit of Nui Ba Den began receiving attacks of increasing intensity and frequency.

Finally on 6 January 1975, without food and water and with nearly all ammunition expended, the company picked up its wounded and withdrew down the mountain to friendly lines.

[13]: 135–6 On the afternoon of November 14, 2021, a landslide occurred in several areas of Mount Bà Đen, with rocks and soil sliding down from the summit.

[14] The following day, authorities from the Management Board of Bà Đen National Tourism Area and the Forest Protection Department inspected the site and determined that the main cause was the displacement of a mass of rocks and soil that had been accumulated for construction purposes on the mountain peak, resulting in a long stretch of flowing mud.

[15] The Bà Đen Mountain Spring Festival takes place annually from the 4th to the end of January, with the key three days being the 4th, 5th, and 6th.

Visitors may hike up trails, however the Núi Bà Đen gondola lift is an alternative route to the top of the temple complex.
