The driest town in the world's driest non-polar desert sits under one of the clearest night skies on the planet, with an annual astronomy festival, salted crust drives across the Salar de Atacama, and pisco sours at 2,400 metres.
San Pedro de Atacama is a town of 3,000 people in the Antofagasta Region of northern Chile at an altitude of 2,438 metres, surrounded by the Atacama Desert, which receives less than one millimetre of rainfall per year in some areas. The European Southern Observatory chose this region for the ALMA telescope array precisely because of the atmospheric conditions: zero humidity, zero light pollution, and 330 clear nights per year. From the edge of town after dark, the Milky Way is visible with the naked eye on any clear night.
The town is a base for exploring the surrounding landscape: the Salar de Atacama (a vast salt flat 10 kilometres south), the Valle de la Luna (a geological replica of lunar terrain), the CONAF-managed flamingo lagoons, and the El Tatio geyser field (4,300 metres, accessible by pre-dawn four-wheel drive). The Atacama Desert Festival and Carnaval Atacameño in August draw on Atacameño indigenous culture and celebrate the surrounding landscape with music, traditional dress, and community events. The permanent feature is the night sky: guided stargazing tours run from the Perché No observatory and SPACE on Tocopilla Street nightly.

Day-by-day breakdown
Valle de la Luna is 13 kilometres west of San Pedro on the road to Calama. Entry is 5,000 CLP. The valley's salt and clay formations create a landscape that genuinely resembles the moon's surface at certain light angles. Visit at sunset (the standard tour option from most agencies) for the best colours. Stargazing tours depart from town at 9pm; book in advance. Tours cost 30,000–50,000 CLP and include telescope observation time with an astronomer guide.
El Tatio is at 4,300 metres: dress accordingly (temperatures before sunrise at the geyser field are -5°C to -10°C in all seasons). Tours depart at 4am from San Pedro. The geysers are active between 6am and 9am; steam columns reach up to 6 metres. Tour operators include breakfast at the site and stop at the thermal pools on the way down for a hot swim. Full-day tours including Machuca village return by 1pm.
The August carnival draws on the Lickanantay (Atacameño) indigenous traditions: traditional dress, Andean music (charango, zampoña, and bombo instruments), and communal food preparation. Events centre on the Plaza de Armas. Traditional Andean foods including humitas (corn tamales), empanadas, and llama stew are sold from stalls. The atmosphere is community-oriented rather than tourist-facing.
The Salar de Atacama is 10 kilometres south of town: a 3,000-square-kilometre salt flat. The CONAF-managed Laguna Chaxa within the salar is home to three flamingo species. Entry to the salar CONAF sector is 5,000 CLP. The flamingos are present year-round; early morning and late afternoon are the best observation times. Most tours combine the salar with Toconao village, an adobe settlement known for its fig orchards.
