The Atacama Desert — the driest on Earth: El Tatio geysers, Valle de la Luna, flamingo lagoons, and skies free of clouds year-round.
The main base for exploring the Atacama Desert — the driest desert on Earth — San Pedro de Atacama is a town of around 11,000 people in northern Chile, at an elevation of 2,408 m. A small adobe-brick town surrounded by otherworldly landscapes: salt flats, active volcanoes, geysers at 4,300 m, pink flamingo lagoons at 4,000 m, and the Valley of the Moon. The Atacama has the clearest skies on the planet for astronomy (the world's largest radio telescope, ALMA, is located nearby). The town is also a crossing point into Bolivia (Uyuni) and Argentina.
The cuisine is Chilean and Atacameño: empanadas, llama (lama), queso de la Atacama, pisco sour. Lunch at a café runs 12–22 USD, dinner at a restaurant 25–50 USD. Tours are the main expense: a typical day tour costs 50–80 USD. A litre of petrol is around 1.20 USD; taxis (scarce) 5–15 USD; bicycle hire 8–15 USD per day. Prices are as of 2026.
El Loa Airport (CJC) in Calama, 100 km away, is served by LATAM, Sky, and JetSMART from Santiago (2 hours, 80–150 USD). Shuttle from Calama to San Pedro: 12–18 USD; taxi: 40–60 USD. Long-distance bus from Santiago takes 22–24 hours (40–70 USD). Cross-border tours to Bolivia — San Pedro to Uyuni, 3 days (200–300 USD) — are popular.
March–November is the dry season (the Atacama is the world's driest desert): daytime temperatures 5–25 °C, nights cold (down to 0 °C). December–February is the Altiplano's summer rainy season — rainfall is light but possible. The altitude of 2,408 m should be taken seriously: avoid alcohol and heavy exertion for the first 24 hours. The El Tatio geysers sit at 4,320 m, where morning temperatures can reach −10 °C even in summer.
