Aeropuerto El Loa (312-348) is a short cab ride south of Calama (US$5). Minibus transfers cost US$4 per person to drop you at your hotel. Taxis (US$35) will drive tourists to San Pedro de Atacama.
Frequent taxi colectivos to Chuquicamata (US$1.40, 15 minutes) leave from Abaroa, just north of Plaza 23 de Marzo.
Car-rental agencies include Hertz (341-380; Av Granaderos 1416) and Avis (363-325; email@example.com; Aeropuerto El Loa). To visit the geysers at El Tatio, rent a 4WD or pickup truck; ordinary cars lack sufficient clearance for the area's rugged roads and river fords.
