The era of the ’60s and the ’70s marked a hike in the number of visitors who traveled to this city, the reason for which was the mineral-rich lake. The water in the lake was believed to treat a variety of ailments including several skin conditions, rheumatism, and even diabetes for that matter. What also helped improve tourism was the Ferrocarril Sarmiento train service that started in 1972 which made it easier for tourists to travel from Buenos Aires to Villa Epecuen. Almost as much as 20,000 tourists would visit the town each summer when the tourism was at its peak.
