The Borovitsa is a 42 km long river in southern Bulgaria, a left tributary of the Arda of the Maritsa drainage. Along its low course and its tributary the Ayladere passes the boundary between the western and the eastern Rhodope Mountains. The river takes its source under the name Hambardere at an altitude of 1,622 m on the northern foothills of the summit of Elvarnika in the Pereliksko–Prespanski Ridge of the western Rhodope Mountains. It initially flows in northeastern direction, gradually turning to the southeast and forming a large arc bulging to the north. Its valley is deep and sparsely forested. The river flows into the northern arm of the Kardzhali Reservoir on the Arda at an altitude of 332 m. It drains the northeastern slopes of the Pereliksko–Prespanski Ridge and the westernmost parts of the Gorata Ridge. Its drainage basin covers a territory of 301 km2.
