Belonging to the province Baoruco, it is located on the eastern side of the Neyba valley, in the mountains of western Yaque del Sur River, which separates it from the municipality of Vicente Noble in the province of Barahona, south of San Juan de la Maguana and east of the Galván township.

Its location over a number of rain shadows through the highlands of Hispaniola from the northeasterly trade winds gives Tamayo a desert climate (Köppen BWh).

The newcomers started their Bohíos and began raising livestock in an enclosure which called Hatice (small pigsty of calves).

In 1908, with the arrival of a large cyclone, the river Yaque del Sur rose and flooded the land of Hatice, destroying this town.

The animals were drowned up above the trees, and four goats that were saved were used to feed children until they reached San Juan de la Maguana and El Cercado with food to help the victims.

In 2007, the City Council received on a monthly basis by ordering the transfer of the General Budget, through the Dominican Municipal League.

The municipality operates seven rural clinics and a city hospital, which make up the physical infrastructure in health care available to Tamayo.

Like other municipalities in the province of Barahona, cases that require specialized medical care are sent to the Jaime Mota regional hospital.
