Salto, Uruguay's third-largest city by population, has developed its tourism offerings for decades around the thermal spas that surround it. Museums, theaters, and attractions for travelers have been built over time, but thermal activity remains of course the primary draw for visitors to Salto. These tourist destinations are renowned in general for their pleasant and agreeable character but also for their health benefits. Here are the three most famous thermal spas in Salto, and likely in Uruguay overall.
The thermal spas bordering Uruguay's third-largest city are all supplied by the same natural freshwater reservoir. The world's third-largest! Indeed, the Guaraní Aquifer extends over 1,190,000 km² and contains a volume of approximately 40,000 km³ of freshwater. This immense underground water table lies beneath four South American countries: Brazil, Argentina, Paraguay, and Uruguay. Although the aquifer dedicates only 3.8% of its surface to the latter compared to 71.4% for Brazil for example, Uruguay benefits greatly from its characteristics to develop its hot springs and therefore its thermal spas.
These waters preserved for millennia beneath the earth's surface contain a high level of minerals, which gives them healing properties for humans. This composition allows for the treatment of several types of skin conditions as well as bone-related ailments such as arthritis. The temperature of the baths ranges between 35 and 42 degrees, which also promotes muscle recovery and reduces the risk of soreness. Uruguay has around 150 wells used to extract this mineral water that is transferred to the country's various thermal spas. Here is a presentation of the most famous ones located in or near Salto.
The Heat of Daymán
The country's various thermal spas are located predominantly in the west, above the Guaraní Aquifer and a few kilometers east of the Río Uruguay, the country's largest river, stretching over 1,800 km. The closest to Salto is the Daymán thermal spa, which turns out to be the hottest in the country. Temperatures can reach 46 degrees! The pure and highly mineralized water attracts many tourists who sometimes prefer its tranquility to the excitement created by the hot springs of Salto Grande, another spa in the city that houses a water park. In any case, these locations are very close and you'll have no trouble testing both if you have time.
The Isolation of Arapey
About sixty kilometers north of Salto lies the Arapey thermal spring. This one stands out for the small population inhabiting the village, which hovers around 300 residents annually. Nonetheless very touristy, this spa is ideal for access and use during low season. The temperature won't change and will always oscillate between 38 and 40 degrees. Here there's no stress—you can simply enjoy your immersed moments and unwind in peace.
The Prairies of Guaviyú
Located midway between Salto and Paysandú, the Guaviyú thermal spa sits within a most natural landscape. Six pools with a maximum depth of 2 meters offer a completely open view of the surrounding countryside, allowing you to contemplate them while seated on smooth stones as the warm water relaxes and works its effects on muscles, skin, and bones. This water is highly dosed in calcium, magnesium, potassium, and fluoride, which amplifies the healing effects.
