We splurged and spent a day at the spa outside of Mendoza. Highlights included mud baths, pools of several temperatures, a giant buffet lunch (including tons of asado — Argentine barbecue), and a wonderful swim in the nearby river canyon. This kind of thing is super popular with Argentines, as evidenced by the busload of vacationing locals we spent the day with, and the throngs who come out on their own to enjoy bbqs and picnics all up and down the river bank. It was pretty great. Here are a few images.
