Calama is just the gateway to San Pedro de Atacama for the most tourists.
However, the nearby Chuquicamata is the world's largest , along with its associated abandoned , and is located just outside of Calama. Tours can be done to visit the mine.

By bus

Two bus stations exist in Calama, the regular where all regular national buses (Turbus, Pullman, etc.) stop, coming from Arica and Iquique (overnight), or Antofagasta (every 2 hr or so). And there are the with the more frequent (at least every 2 hr) and cheaper (CLP$3,000) bus companies of KTur, Atacama2000, etc. serving San Pedro. Make sure you get of the national bus before the Terminal de Buses or you will have to walk back into town 1.5 km to catch the more frequent San Pedro Buses. If you are heading for San Pedro, transferring in Calama is mostly cheaper and faster.

• 
  Normally, overnight buses arrive from Iquique or Arica in the early morning hours, but the bus company will let you sleep on the bus for a few hours until morning so there is no need to book a hotel or hostel.
  

Calama is not large and most of the city centre can be covered on foot. Collectivos (shared taxis) run fixed routes and cost CLP$700, while buses, named with letters of the alphabet, cost about CLP$300.

  Chuquicamata can only be visited on a free guided tour organized by the Chilean state-owned copper company Codelco. Although mining operations run throughout the year, tours are only conducted from Mondays to Fridays, holidays excepted. Reservations need to be made in advance through email at visitas@codelco.cl or through telephone at +56 552322122. You need to provide your name, number of people, number of people of 7 years and below, your country and any medical issues that could influence the tour.
  The tour departs at 13:00 from the on the north side of Calama, at the junction of Central Sur and Granaderos. The office is accessible by Buses B and D, and should not be confused with the Codelco Norte headquarters building opposite the Calama Plaza Mall on Balmaceda.
  Your should wear long trousers, long sleeve shirt and covered shoes. You will get a helmet and warning west at the office. The tour itself is free but you will be asked for a voluntary donation for the children's fund.
  The tour is conducted simultaneously in both English and Spanish. It begins with a circuit around Chuquicamata town, once a thriving company town with banks, restaurants and playgrounds, but which has since been evacuated due to legal and health issues. The bus does not stop for visitors to get off in the town. The tour bus continues into the mine, passing mining trucks and old equipment, and stops to let visitors off at the Mirador, which offers a panoramic view of the central mine. There are some informational posters on the copper and mining extraction process, and a pile of copper ore for visitors to pick through.
  You also can sign up at the local municipal . It's located at Parque El Loa (south part of city)—access to the office is from Avenida O'Higgins (not from inside the park). Otherwise, you can also contact the tourism office in Antofagasta if everything else fails: https://www.sernatur.cl/oficinas-de-informacion-turistica/ - +56 55 2451818 / 2451819 - infoantofagasta@sernatur.cl

• Memorial for '73 DisappearedIn the desert on the way to San Pedro you can find this memorial.

• There's a small amusement park for children off the main square in town.
• And you can go to the mall. There's a movie theater, but be warned, all the movies are in Spanish.
• Diego Delso
  Rent a 4x4 truck and go see Chiu-Chiu, Lasana, and the geysers de Tatio. For around CLP$40,000 per day, you can rent a 4x4 truck. Chiu-Chiu is about 35 km North-East of Calama. There are interesting ruins, a lagoon, and some old churches. Lasana is a beautiful canyon winding through the desert. It's green and really different. Then, a several hour drive across the salt flats and through some very rugged roads brings you to the Geysers of Tatio. If you camp on the north side of the geysers, and come down in the morning, you can get in for free (otherwise around CLP$16,000 for a truck and four people). The geysers are at about 4,200 m, and you hit about 4,700 meters coming in from the north. So, it is a good idea to get well acclimatised ahead. In May it is very cold at night, up to -15 °C. A very cool experience.
