Fifteen kilometres northeast of Tay Ninh, Nui Ba Den rises 850m above the rice paddies, corn, cassava (manioc) and rubber plantations of the surrounding countryside. Over the centuries Nui Ba Den has served as a shrine for various peoples of the area, including the Khmer, Chams, Vietnamese and Chinese, and there are several interesting cave temples here. The summits of Nui Ba Den are much cooler than the rest of Tay Ninh province, most of which is only a few dozen metres above sea level.
