The cultural identity of Pica is shaped by indigenous traditions, Spanish colonial influences, and centuries of agricultural innovation. Archaeological evidence indicates that pre-Columbian cultures thrived in Pica thanks to the availability of fresh water—a rare resource in the Atacama Desert. When Spanish explorers arrived in the 16th century, Pica became a strategic agricultural center supplying citrus fruits and other goods to surrounding settlements.
The earliest inhabitants of the Pica oasis were the **Atacameño** and **Aymara** peoples, both known for their sophisticated irrigation techniques. Their terraces and canals allowed crops to flourish in the dry climate, enabling the oasis to become a vital trading hub between the Andes and the Pacific coast.
During the colonial era, Spanish settlers expanded agricultural production and introduced new citrus species. Pica's lime production soon became famous across the region. Even today, traditions such as **fiestas religiosas**, adobe architecture, and agricultural festivals reflect the blend of indigenous and colonial cultural heritage.
Pica may be small, but its attractions offer a deep connection to nature, culture, and relaxation. Below are the most popular attractions that make Pica a unique destination in the Tarapacá Region.
The Termas de Pica are one of the most iconic attractions in the area. These natural geothermal waters emerge at temperatures between 30°C and 38°C, offering visitors a soothing escape from the desert environment. The two main pools—**Cocha Resbaladero** and **Cocha Cabuza**—are surrounded by rock formations, creating a natural spa atmosphere.
The agricultural fields surrounding Pica are filled with lime orchards producing the world-famous limón de Pica. These small limes have a strong aroma and acidic flavor, making them a favorite ingredient in Chilean cuisine and cocktails such as **Pisco Sour de Pica**.
"The limón de Pica is more than a fruit—it's a cultural symbol of the Tarapacá Region and a representation of resilience in the world's driest desert."
Just a few kilometers from Pica lies **Matilla**, another oasis settlement. Matilla is known for its picturesque vineyards and the historic Church of San Antonio, built in the early 18th century. Visitors often combine a trip to Pica and Matilla due to their close proximity and shared cultural heritage.

Historically, indigenous communities mastered the art of groundwater management, allowing citrus and vegetables to flourish. A modern study from the Tarapacá agricultural authority found that Pica’s underground aquifers have unusually stable mineral content and temperature, making irrigation efficient and agriculture surprisingly sustainable.
Today, Pica exports limes, mangoes, and figs across Chile. Despite the arid climate, its oasis continues to serve as an example of how traditional knowledge and modern sustainability techniques can coexist.
The best time to visit Pica is between **April and November**, when temperatures are mild and there is virtually no rain. December to March can still be pleasant, but travelers should be aware of occasional tropical rainfall from the Bolivian Winter.
