Oficina Salitrera Humberstone y Santa Laura

UNESCO World Heritage ghost towns showcasing the remains of Peru's nitrate mining era with preserved workers' villages, machinery, and period infrastructure. These hauntingly beautiful abandoned sites tell the story of early 20th-century industrial labor in the Atacama.

Things to do

• Explore the Central Plaza — Walk through the heart of the abandoned workers' settlement where the clock tower and administrative buildings stand as monuments to early 20th-century industrial life.
• Tour the Mining Machinery — Examine preserved steam engines, ore carts, and extraction equipment that demonstrate the scale and technology of nitrate production during the Pampas mining boom.
• Visit the Workers' Housing — Wander through restored and semi-restored residential quarters with original furniture and personal artifacts that reveal how miners and their families lived during the site's operational years.
• Examine the Theater — Discover the ornate social hall where workers gathered for entertainment and community events, now a haunting reminder of leisure in the desert.
• Inspect the Processing Plant — View the industrial infrastructure including boilers, vats, and refining equipment that processed raw nitrate into exportable products.
• Photograph the Church — Capture images of the whitewashed wooden chapel that once served the spiritual needs of the community and remains one of the site's most photogenic structures.

Food to try

• Pastel de choclo — A traditional Chilean corn pie with meat filling, commonly prepared in Tarapacá and available in nearby towns like Iquique as a hearty lunch option.
• Empanadas de pino — Baked pastries filled with seasoned ground beef, onions, and olives, a staple throughout northern Chile that makes for convenient on-site sustenance.
• Ceviche from Iquique — Fresh fish marinated in citrus, a Peruvian-influenced dish reflecting the region's coastal proximity, best enjoyed in nearby port towns after visiting the ghost town.
• Pan de campo — Traditional Chilean country bread baked fresh daily, a simple but essential accompaniment to meals throughout the Atacama region.
• Agua de algarrobo — A sweet beverage made from carob pods native to the Atacama Desert, offering refreshment in the arid climate and reflecting local agricultural heritage.

Local customs & good to know

• Bring abundant water and sun protection — The Atacama Desert location means extreme sun exposure and virtually no shade; carry at least 3 liters of water per person and high-SPF sunscreen to stay safe during exploration.
• Respect the preservation efforts — UNESCO World Heritage designation means the site is carefully maintained; stay on marked paths, do not remove artifacts, and follow ranger guidance to protect this irreplaceable historical record.
• Visit early morning or late afternoon — Daytime temperatures in the Atacama exceed 35°C; visiting at cooler times of day improves comfort and photo quality while reducing dehydration risk during your 2–3 hour tour.
• Learn the nitrate industry history beforehand — Understanding the context of the Chilean salitrera boom (1880–1930s) and the labor conditions enriches your interpretation of the abandoned structures and personal stories left behind.
