Ba Phnom is located in Chheur Kach commune, Ba Phnom district, about 78 kilometers east of Phnom Penh and 45 kilometers south of Prey Veng provincial town. Visitors traveling from Phnom Penh along National Road 1 should turn left at Kampong Sneung market and go about 7 kilometers.

There are four mountains in Ba Phnom-Phnom Sampeou, Phnom Laang, Phnom Thom and Phnom Banhchor. Ba Phnom was once the ancient city Nokor Phnom, which was located near these mountains in Ba Phnom district. Few remnants of the city remain. Among those that can be seen are pieces of the ancient temple Prasat Chan, which was located in front of Wat Vihear Kuk, near the foot of Phnom Sampeou in Cheung Phnom commune. At one time, the city also had a palace and a hall, but both have been destroyed by years of war.

The view from the top of Ba Phnom is very picturesque. There is a big, rocky cave near the mountaintop that shelters wildlife. At the foot of mountain, there is a pagoda, Wat Phnom, also known as Wat Bat Phnom.

A road circles the mountains, and a big pond lies the east of them. People live around the mountains. Ba Phnom has been eyed for tourism development east of the Mekong River, because the area attracts many people on weekends and during Cambodian festivals.
