8 Sights in San Pedro de Atacama, Chile (with Map and Images)

El Valle de la Luna is located 13 kilometres (8 mi) west of San Pedro de Atacama, in the north of Chile in the Cordillera de la Sal, in the Atacama desert. It has various stone and sand formations which have been carved by wind and water. It has an impressive range of color and texture, looking somewhat similar to the surface of the Moon. There are also dry lakes where the composition of salt makes a white covering layer of the area. It presents diverse saline outcrops which appear like man-made sculptures. There are also a great variety of caverns. When the sun sinks it defines the landscape while the wind blows among the rocks and the sky passes from pink color to purple and finally black. Valle de la Luna is a part of the Reserva Nacional los Flamencos and was declared a Nature Sanctuary in 1982 for its natural environment and strange lunar landscape, from which its name is derived. The Atacama desert is also considered one of the driest places on earth, as some areas have not received a single drop of rain in hundreds of years. A prototype for a Mars rover was tested there by scientists because of the valley's dry and forbidding terrains.

The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of 66 radio telescopes in the Atacama Desert of northern Chile, which observe electromagnetic radiation at millimeter and submillimeter wavelengths. The array has been constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau – near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment. This location was chosen for its high elevation and low humidity, factors which are crucial to reduce noise and decrease signal attenuation due to Earth's atmosphere. ALMA provides insight on star birth during the early Stelliferous era and detailed imaging of local star and planet formation.

The Atacama Cosmology Telescope (ACT) was a cosmological millimeter-wave telescope located on Cerro Toco in the Atacama Desert in the north of Chile. ACT made high-sensitivity, arcminute resolution, microwave-wavelength surveys of the sky in order to study the cosmic microwave background radiation (CMB), the relic radiation left by the Big Bang process. Located 40 km from San Pedro de Atacama, at an altitude of 5,190 metres (17,030 ft), it was one of the highest ground-based telescopes in the world.

The Cosmology Large Angular Scale Surveyor (CLASS) is an array of microwave telescopes at a high-altitude site in the Atacama Desert of Chile as part of the Parque Astronómico de Atacama. The CLASS experiment aims to improve our understanding of cosmic dawn when the first stars turned on, test the theory of cosmic inflation, and distinguish between inflationary models of the very early universe by making precise measurements of the polarization of the Cosmic Microwave Background (CMB) over 65% of the sky at multiple frequencies in the microwave region of the electromagnetic spectrum.

The Church of San Pedro de Atacama is a Catholic church in San Pedro de Atacama, Chile. Constructed during the Spanish colonial period, it is reportedly the second oldest church in Chile. Indigenous adobe material was used in the church's construction, whose appearance is characterized as simple and elegant. The church was built in the seventeenth century, underwent modifications in the eighteenth century, and additions were made in the nineteenth century. The church was declared a historical monument in 1951.

Puritama Hot Springs is a series of eight large pools of geothermal spring water located at the bottom of a canyon in the Atacama Desert, in the Antofagasta Region in the north of Chile. It is located at an altitude of 3,475 meters above sea level, 30 km northeast of the town and commune of San Pedro de Atacama and 348 km northeast of Antofagasta, and is a popular tourist attraction.
