The Sairecabur volcanic group is a chain of stratovolcanoes located approximately 38 km (24 mi) northeast of San Pedro de Atacama, and directly south of the Putana Volcano, on the border between Bolivia and Chile. This volcanic group contains at least ten peaks, the highest of which is Cerro Sairecabur at 5,971 m (19,590 ft). Other peaks in the complex include Cerro Saciel, Cerro Ojos del Toro, directly north of Cerro Sairécabur, Curiquinca (5,722 m (18,773 ft)), Escalante or El Apagado (5,819 m (19,091 ft)) and Cerro Colorado (5,728 m (18,793 ft)), about 12 km (7 mi) to the north of Cerro Sairecabur. Several, now abandoned, sulfur mines are located in the complex, including Saciel, Ojos del Toro and El Apagado.

The word Sairecabur is the Castilianization of the Kunza name used by the Atacameño (also known as Likan Antai) people to refer to the volcano: saire - rain, cabur - mountain, thus meaning "Rainmountain". Cerro Sairecabur rises at the northern end of a 4.5 km wide caldera which is breached and intersected on the north-end by a 500 m (1,640 ft)-wide volcanic crater.
The Receiver Lab Telescope (RLT) is located on Cerro Sairecabur, at am altitude of 5,525 m (18,127 ft).
