I am in Argentina as a tourist, so every 90 days I have to cross the border into another country and get my passport stamped and then when I cross back into Argentina I can stay another 90 days without problems. This past weekend,I was lucky to have Rolando drive me to Salto, Uruguay which is about 12 hours from Cordoba by car. We only went for a 2-day trip and traveling all those hours is very tiring but in the end it was worth it. In Salto, Uruguay they have hot springs. On Sunday morning, we took advantage of this and swam and relaxed in the hot spring pools. It was a sunny day but the air was very crisp and cold, so being inside the hot water made it even better! My skin felt great afterwards! When we left on Sunday afternoon there was a tour bus entering with lots of people coming to enjoy all the medicinal properties of the hot spring waters (which are listed in this link I provided)
