[2] Sibut sits on the banks of the Kémo, a minor tributary of the Ubangi River about 150 km (93 mi) long.

Formerly an important route of supply and communication between Fort de Possel on the Ubangi and the French settlements around Lake Chad, the river is now non-navigable even with small watercraft.

In 1952, American Baptist missionary Margery Benedict established a medical clinic and dispensary at Fort Sibut.

In 1982, President Andre Kolingba traveled to Sibut to award her the Order of Gratitude for 30 years of service.

Local food in street cafes include gozo (cassava) and peanut spinach sauce, along with various species of bushmeat.
