Arenillas, situated in the southwestern corner of Ecuador within the El Oro Province, is a city of significant strategic and ecological importance due to its proximity to the Peruvian border. Located on an arid coastal plain at an elevation of only 15 meters above sea level, the town serves as a key link for cross-border trade and logistics. Historically, the region gained prominence during the 1941 Peruvian-Ecuadorian War, as it was a site of major military engagements. Arenillas was formally established as a canton on November 11, 1955. One of the area's most notable features is the Arenillas Ecological Reserve, which covers over 13,000 hectares and protects one of the last remaining stands of tropical dry forest on the coast. The city is also home to the Tahuín Dam, a critical infrastructure project that provides water for the irrigation of extensive banana and cacao plantations while serving as a popular recreational spot. The climate is characterized by high temperatures and low rainfall, shaping the local biodiversity. Today, the economy relies on international trade with Peru, agriculture (particularly citrus fruits and tobacco), and a thriving shrimp farming industry in the coastal sectors of the canton.
